122-402: Rocking stones (also known as logan stones or logans ) are large stones that are so finely balanced that the application of just a small force causes them to rock. Typically, rocking stones are residual corestones formed initially by spheroidal weathering and have later been exposed by erosion or glacial erratics left by retreating glaciers . Natural rocking stones are found throughout

244-800: A Cornish expression for the movement that someone makes when inebriated: Such stones are common in Britain and other places around the world. For example, in Galicia , rocking stones are called pedras de abalar ; some examples of these are along the Costa da Morte , particularly around Muxía ; they include the Pedras de Barca . Pliny the Elder (23–79) wrote about a rock near Harpasa (in Caria , Asia Minor) "that can be moved with one finger, but that also resists

366-420: A laboratory or factory . Mining in a wider sense comprises extraction of any resource (e.g. petroleum , natural gas , salt or even water ) from the earth. Mining of rock and metals has been done since prehistoric times. Modern mining processes involve prospecting for mineral deposits, analysis of the profit potential of a proposed mine, extraction of the desired materials, and finally reclamation of

488-430: A phono-semantic match . Archaeological studies from 2021 found evidence of settlement on the islands before the arrival of Norse settlers, uncovering burnt grains of domesticated barley and peat ash deposited in two phases: the first dated between the mid-fourth and mid-sixth centuries, and another between the late-sixth and late-eighth centuries. Researchers have also found sheep DNA in lake-bed sediments dating to

610-584: A claim as one of the oldest continuously running parliaments in the world. The islands' endonym Føroyar , as well as its English name Faroe Islands (alt. Faeroe or the Faroes ), derive from the Old Norse Færeyjar . The second element oyar ('islands') is a holdover from Old Faroese ; sound changes have rendered the word's modern form as oyggjar . Names for individual islands (such as Kalsoy and Suðuroy ) also preserve

732-402: A fourth class of rocks alongside igneous, sedimentary, and metamorphic. Rock varies greatly in strength, from quartzites having a tensile strength in excess of 300 MPa to sedimentary rock so soft it can be crumbled with bare fingers (that is, it is friable ). (For comparison, structural steel has a tensile strength of around 350 MPa. ) Relatively soft, easily worked sedimentary rock

854-532: A group of islands north of Scotland of very similar character to the Faroe Islands in his work De mensura orbis terrae ("Of the measure of the worlds of the earth"). In this text, Dicuil describes "a group of small islands (...) Nearly all of them (...) separated by narrow stretches of water" that were "always deserted since the beginning of time" and previously populated by heremitae ex nostra Scotia (" hermits from our land of Ireland/Scotland") for almost

976-433: A huge impact on the cultural and technological development of the human race. Rock has been used by humans and other hominids for at least 2.5 million years . Lithic technology marks some of the oldest and continuously used technologies. The mining of rock for its metal content has been one of the most important factors of human advancement, and has progressed at different rates in different places, in part because of

1098-607: A hundred years before being displaced by the arrival of Norse "pirates". Church argued that these were likely the eremitic Papar that had similarly resided in parts of Iceland and Scotland in the same period. Writers like Brøgger and Peter Andreas Munch had drawn the same connections from Dicuil's writings, with the latter arguing that these Papar were also the ones to bring sheep to the islands. A ninth-century voyage tale concerning Irish saint Brendan , one of Dicuil's contemporaries, details him visiting an unnamed northern group of islands; this has also been argued to be referring to

1220-598: A lever, but used to move quite easily, before a band of sailors from the nearby Halifax garrison rocked it into a more stable configuration in the 1890s, and before its base was worn down by excessive rocking in the 1980s and '90s when a park was developed around it at Kidston Lake , in the Spryfield area of the municipality. It used to be a popular picnic destination; in Victorian times, people would travel from Halifax, climb upon it and spread their lunches, while enjoying

1342-457: A millennium, was dissolved and replaced by a Danish judiciary, and the post of løgmaður ( lawspeaker ) was likewise replaced by a Danish-appointed amtmand (equivalent to a governor-general). As part of its mercantilist economic policy, Denmark maintained a monopoly over trade with the Faroe Islands and forbade the Faroese from trading with other countries. The trade monopoly in

1464-552: A new sewer system in the neighbourhood dislodged the rock, so it no longer balances. A rocking stone in Pembrokeshire is described in Gibson 's edition of Camden's Britannia , from a manuscript account by George Owen : Cromwell 's soldiers rendered the rocking stone of Pembrokeshire immovable after Mr. Owen had described it. They reportedly destroyed it because they felt it encouraged superstition. Another rocking stone

1586-495: A period of high volcanic activity in the Early Palaeogene around 50–60 million years ago. The islands are built up in layers of different lava flows (basalt) alternating with thin layers of volcanic ash (tuff). The soft ash and the hard basalt thus lie layer upon layer in narrow and thick strips. The soft tuff or ash zones erode away relatively quickly, and the hard lump of basalt above the eroded tuff falls away, forming

1708-583: A push made with the whole body." Ptolemy ( circa 90–168) wrote about the Gygonian rock, which he wrote "can only be moved with an asphodel and remains immovable by force." There are stones in Iona called na clachan-bràth , within the precincts of a burial ground, and placed on the pedestal of a cross, and have been according to Pennant , the supports of a tomb. A massive 90 to 95 ton glacial erratic boulder near Halifax , Nova Scotia, can still be rocked with

1830-430: A republic in 1944 served as a precedent and a model in the mind of many Faroe Islanders. The Løgting held an independence referendum on 14 September 1946 , resulting in a very narrow majority for independence; 50.73% voted in favour and 49.27% against; the margin was only 161 votes. The Løgting subsequently declared independence on 18 September 1946; this declaration was annulled by Denmark on 20 September, arguing that

1952-527: A short distance to the south. Snow also is seen at a much higher frequency than on outlying islands nearby. The area receives on average 49 frosts a year. The collection of meteorological data on the Faroe Islands began in 1867. Winter recording began in 1891, and the warmest winter occurred in 2016–17 with an average temperature of 6.1 °C (43 °F). The Faroes belong to the Faroe Islands boreal grasslands ecoregion. The natural vegetation of

2074-562: A source area and then transported to the place of deposition by water , wind , ice , mass movement or glaciers (agents of denudation ). About 7.9% of the crust by volume is composed of sedimentary rocks, with 82% of those being shales, while the remainder consists of 6% limestone and 12% sandstone and arkoses . Sedimentary rocks often contain fossils . Sedimentary rocks form under the influence of gravity and typically are deposited in horizontal or near horizontal layers or strata , and may be referred to as stratified rocks. Sediment and

2196-661: A survey sponsored by NATO , the British Museum (Natural History) and the Carlsberg Foundation, is preserved in the Ulster Museum (catalogue numbers: F3195–F3307). It is one of ten exsiccatae sets. A few small plantations consisting of plants collected from similar climates such as Tierra del Fuego in South America and Alaska thrive on the islands. The bird fauna of the Faroe Islands

2318-713: A texture are referred to as foliated ; the remainders are termed non-foliated. The name of the rock is then determined based on the types of minerals present. Schists are foliated rocks that are primarily composed of lamellar minerals such as micas . A gneiss has visible bands of differing lightness , with a common example being the granite gneiss. Other varieties of foliated rock include slates , phyllites , and mylonite . Familiar examples of non-foliated metamorphic rocks include marble , soapstone , and serpentine . This branch contains quartzite —a metamorphosed form of sandstone —and hornfels . Though most understanding of rocks comes from those of Earth, rocks make up many of

2440-518: A tropical system. The climate varies greatly over small distances, due to the altitude, ocean currents, topography, and winds. Precipitation varies considerably throughout the archipelago. In some highland areas, snow cover may last for months with snowfalls possible for the greater part of the year (on the highest peaks, summer snowfall is by no means rare), while in some sheltered coastal locations, several years pass without any snowfall whatsoever. Tórshavn receives frosts more often than other areas just

2562-603: A westward ice mass have eroded the intervening mountain range into a narrow ridge. The Faroe Islands are a self-governing country under the external sovereignty of the Kingdom of Denmark. The Faroese government holds executive power in local government affairs. The head of the government is called the Løgmaður ("Chief Justice") and serves as Prime Minister and head of the Faroese Government. Any other member of

2684-670: A witch. The Brimham rocking stone in Yorkshire is said to rock only for the efforts of an honest man. The rocking stone at Land's End was said to have been placed there by a giant who used it to rock himself to sleep. It was claimed that the Logan Stone in Treen could cure childhood diseases. The children were rocked on the Logan Stone in certain seasons. People say that the charm was broken when Lieutenant Goldsmith dislodged

2806-502: Is Lítla Dímun . The islands are rugged and rocky with some low peaks; the coasts are mostly cliffs. The highest point is Slættaratindur in northern Eysturoy , 882 metres (2,894 ft) above sea level . The Faroe Islands are made up of an approximately six-kilometres-thick succession of mostly basaltic lava that was part of the great North Atlantic Igneous Province during the Paleogene period. The lavas were erupted during

2928-475: Is 11 feet (3.4 m) long, 4 feet (1.2 m) deep, and 6 feet (1.8 m) wide. It was toppled by Shrubsall, the governor of Pendennis, and his men about 1650 during Cromwell's Commonwealth. One rumoured motivation for the dislodging was a purported prophecy of Merlin , who supposedly said that Men Amber would stand until England had no king. Rev. Dr. William Stukeley wrote: William Borlase in his 1754 book Antiquities of Cornwall , claimed that Men Amber

3050-493: Is a SSSI for Geology in its own right. Often wear, erosion, or human intervention has resulted in the dislodging of rocking stones. A well-known rocking stone or logan stone was located at Sharpitor near Lustleigh on Dartmoor . It was also called the Nutcrackers Stone, sometimes seen on Ordnance Survey maps. The huge stone once lay overhanging Lustleigh Cleave until 1951, when it was deliberately pushed down

3172-522: Is a local domestic sheep breed, the Faroe sheep (depicted on the coat of arms ), and there once was a variety of feral sheep , which survived on Lítla Dímun until the mid-nineteenth century. Grey seals ( Halichoerus grypus ) are common around the shorelines away from human habitations. Several species of cetacea live in the waters around the Faroe Islands. Best known are the long-finned pilot whales ( Globicephala melaena ), which still are hunted by

3294-466: Is dominated by seabirds and birds attracted to open land such as heather , probably because of the lack of woodland and other suitable habitats. Many species have developed special Faroese sub-species such as the common eider , common starling , Eurasian wren , and black guillemot . The pied raven , a colour morph of the North Atlantic subspecies of the common raven , was endemic to

3416-458: Is formed through the cooling and solidification of magma or lava . This magma may be derived from partial melts of pre-existing rocks in either a planet 's mantle or crust . Typically, the melting of rocks is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Igneous rocks are divided into two main categories: Magmas tend to become richer in silica as they rise towards

3538-648: Is in the center of a loose collection of stones in the village of Lugar in East Ayrshire. The Lamargle stone rests on two stones. Local legend has it that the Lamargle stone used to rock, but it no longer does. The Witch's Stone or Boarstone on the Craigs o'Kyle is recorded by the author John Smith as having rocked. The Clochoderick Stone near Howwood and Kilbarchan in Renfrewshire used to rock, and it

3660-494: Is next in importance. About 65% of the Earth's crust by volume consists of igneous rocks. Of these, 66% are basalt and gabbro , 16% are granite, and 17% granodiorite and diorite . Only 0.6% are syenite and 0.3% are ultramafic . The oceanic crust is 99% basalt, which is an igneous rock of mafic composition. Granite and similar rocks, known as granitoids , dominate the continental crust . Sedimentary rocks are formed at

3782-522: Is reflected today in the Faroese genetic makeup and a number of loanwords from Old Irish. A traditional name for the islands in Irish , Na Scigirí , possibly derives from Eyja-Skeggjar , ("Island-Beards"), a nickname given to island dwellers. According to Færeyinga saga , many of the Norwegian settlers in particular were spurred by their disapproval of the monarchy of Harald Fairhair , whose rule

3904-571: Is said that the Druids used it to judge people. The accused was made to sit on the stone and by the way it moved, the Druids judged the innocence or guilt of the individual. It is also said to be the burial place of Rhydderch Hael , King of Strathclyde, who was the victor at the Battle of Arderydd near Arthuret in the Borders. His victory brought Christianity to Strathclyde. This stone is very unusual and

4026-505: Is the strange and virtuous property, It moves obsequious to the gentlest touch Of him whose breast is pure; but to a traitor, Tho' ev’n a giant’s prowess nerv’d his arm, It stands as fixt as Snowdon. However, another reason that the Logan Rock of Treen is remembered is that it was the center of a famous drama. In April 1824, Lieutenant Hugh Goldsmith, R. N. (nephew of the famous poet Oliver Goldsmith ), and 10 or 12 of his crew of

4148-453: Is the study of Earth and its components, including the study of rock formations. Petrology is the study of the character and origin of rocks. Mineralogy is the study of the mineral components that create rocks. The study of rocks and their components has contributed to the geological understanding of Earth's history, the archaeological understanding of human history, and the development of engineering and technology in human society. While

4270-506: The Folketing . Until 2007, there were seven electoral districts, which were abolished on 25 October of that year in favour of a single nationwide district. Administratively, the islands are divided into 29 municipalities ( kommunur ) within which there are 120 or so settlements . There are also the six traditional s ýslur : Norðoyar , Eysturoy , Streymoy , Vágar , Sandoy , and Suðuroy . While no longer of any legal significance,

4392-764: The Hoyvík Agreement . In the Nordic Council , they are represented as part of the Danish delegation. In certain sports, the Faroe Islands field their own national teams. They did not become a part of the European Economic Community in 1973, instead keeping autonomy over their own fishing waters; as a result, the Faroe Islands are not a part of the European Union today. The Løgting, albeit suspended between 1816 and 1852, holds

4514-516: The Kingdom of Denmark . The official language of the country is Faroese , which is closely related to and partially mutually intelligible with Icelandic . Located a similar distance from Iceland , Norway , and the United Kingdom , the islands have a total area of about 1,400 square kilometres (540 sq mi) with a population of 54,676 as of August 2023. The terrain is rugged, and

4636-631: The Treaty of Kiel along with Greenland and Iceland , and the Løgting was subsequently replaced by a Danish judiciary. Following the re-establishment of the Løgting and an official Faroese orthography , the Faroese language conflict saw Danish being gradually displaced by Faroese as the language of the church, public education and law in the first half of the 20th century. The islands were occupied by

4758-534: The Union Party ( Sambandsflokkurin ), founded in 1906, which supported Faroese literature but opposed its usage in education; and the Self-Government party ( Sjálvstýrisflokkurin ), which sought to introduce Faroese as the official language in all public spheres and additionally demanded increased political autonomy for the islands. The Faroese language gradually won out; laws and protocols of

4880-417: The history of geology includes many theories of rocks and their origins that have persisted throughout human history, the study of rocks was developed as a formal science during the 19th century. Plutonism was developed as a theory during this time, and the discovery of radioactive decay in 1896 allowed for the radiocarbon dating of rocks. Understanding of plate tectonics developed in the second half of

5002-635: The subpolar oceanic climate (Cfc) is windy, wet, cloudy and cool. Despite the northerly climate, the temperatures are moderated by the Gulf Stream and average above freezing throughout the year, hovering around 12 °C (54 °F) in summer and 5 °C (41 °F) in winter. As a result of its northerly latitude and proximity to the Arctic Circle , the islands experience perpetual civil twilight during summer nights and very short winter days. The capital and largest city, Tórshavn , receives

5124-657: The 16th and 17th centuries, arguing that the West Norse-speaking settlers, whose word for sheep was sauðr instead of the East Norse fær , could not have coined it from this exact origin. Debes surmised that it could have derived from fjær ('far'), while Hammershaimb leaned towards fara ('to go, to travel'). Others have theorised an Old Irish origin: relating it to the etymologies of neighbouring Orkney and Shetland , Scottish writers James Currie and William J. Watson suggested respectively

5246-399: The 20th century. Rocks are composed primarily of grains of minerals, which are crystalline solids formed from atoms chemically bonded into an orderly structure. Some rocks also contain mineraloids , which are rigid, mineral-like substances, such as volcanic glass , that lack crystalline structure. The types and abundance of minerals in a rock are determined by the manner in which it

5368-576: The British during the Second World War , who refrained from governing Faroese internal affairs: inspired by this period of relative self-government and the declaration of Iceland as a republic in 1944 , the islands held a referendum in 1946 that resulted in a narrow majority for independence. The results were annulled by Christian X , and subsequent negotiations led to the Faroe Islands being granted home rule in 1948. While remaining part of

5490-649: The Craigs of Kyle near Coylton in Ayrshire. It weighs around 30 tons and rests upon two or three stones. A large standing stone known as Wallace's stone is recorded to have stood nearby. A rocking stone is found near Loch Riecawr in South Ayrshire . In the parish of North Carrick in the Straiton District in South Ayrshire , about a quarter of a mile to the west of the White Laise, and near

5612-442: The Earth's crust, or lava cools on the ground surface or the seabed. Sedimentary rocks are formed by diagenesis and lithification of sediments , which in turn are formed by the weathering , transport, and deposition of existing rocks. Metamorphic rocks are formed when existing rocks are subjected to such high pressures and temperatures that they are transformed without significant melting. Humanity has made use of rocks since

5734-467: The Earth's surface, a process called magma differentiation . This occurs both because minerals low in silica crystallize out of the magma as it begins to cool ( Bowen's reaction series ) and because the magma assimilates some of the crustal rock through which it ascends ( country rock ), and crustal rock tends to be high in silica. Silica content is thus the most important chemical criterion for classifying igneous rock. The content of alkali metal oxides

5856-503: The Earth's surface: temperatures greater than 150 to 200 °C and pressures greater than 1500 bars. This occurs, for example, when continental plates collide. Metamorphic rocks compose 27.4% of the crust by volume. The three major classes of metamorphic rock are based upon the formation mechanism. An intrusion of magma that heats the surrounding rock causes contact metamorphism—a temperature-dominated transformation. Pressure metamorphism occurs when sediments are buried deep under

5978-478: The Faroe Islands had a parliament ( Løgting ), which was abolished in 1816, and the Faroe Islands were to be governed as an ordinary Danish amt (county), with the Amtmand as its head of government. In 1851, the Løgting was reinstated, but, until 1948, served mainly as an advisory body. The islands are home to a notable independence movement that has seen an increase in popular support within recent decades. At

6100-517: The Faroe Islands is dominated by arctic-alpine plants, wildflowers, grasses, moss, and lichen. Most of the lowland area is grassland and some is heath, dominated by shrubby heathers, mainly Calluna vulgaris . Among the herbaceous flora that occur in the Faroe Islands is the cosmopolitan marsh thistle, Cirsium palustre . Although it is often asserted that the islands are naturally treeless, several tree species, among them shrubby willows ( salix ), junipers ( juniperus ), and stunted birches, colonized

6222-557: The Faroe Islands on 30 March 1948. This agreement granted the islands a high degree of autonomy, and Faroese finally became the official language in all public spheres. In 1973 the Faroe Islands declined to join Denmark in entering the European Economic Community (EEC); as a result, the islands are not part of the European Union (EU) today (although as Danish citizens, Faroe Islanders are still considered EU citizens). Following

6344-557: The Faroe Islands was eventually abolished in 1856, after which the area developed into a modern fishing-based economy with its own fishing fleet . In 1846, the Faroe Islands finally regained formal political representation when they were allocated two seats in the Danish Rigsdag ; the Løgting itself was reinstated as an advisory body to the amtmand in 1852. An official Faroese orthography was first introduced in 1846 by Lutheran minister Venceslaus Ulricus Hammershaimb , returning

6466-412: The Faroe Islands, but now has become extinct; the ordinary, all-black morph remains fairly widespread in the archipelago. Only a few species of wild land mammals are found in the Faroe Islands today, all introduced by humans. Three species are thriving on the islands today: mountain hare ( Lepus timidus ), brown rat ( Rattus norvegicus ), and the house mouse ( Mus musculus ). Apart from these, there

6588-560: The Faroe Islands, though not nearly as conclusively. A number of toponyms around the islands refer to the Papar and the Irish, such as Paparøkur near Vestmanna and Papurshílsur near Saksun . Vestmanna is itself short for Vestmannahøvn ("harbour of the Westmen "). Tombstones in a churchyard on Skúvoy display a possible Gaelic origin or influence. Old Norse-speaking settlers arrived in

6710-528: The Faroe Islands, with cold summers and near-continuous subpolar winds. The following species from Tierra del Fuego , Drimys winteri , Nothofagus antarctica , Nothofagus pumilio , and Nothofagus betuloides , have been successfully introduced to the Faroe Islands. A non-Chilean species that has been introduced is the black cottonwood , also known as the California poplar ( Populus trichocarpa ). A collection of Faroese marine algae resulting from

6832-493: The Kingdom of Denmark to this day, the Faroe Islands have extensive autonomy and control most areas apart from military defence , policing , justice and currency , with partial control over its foreign affairs . Because the Faroe Islands are not part of the same customs area as Denmark, they have an independent trade policy and are able to establish their own trade agreements with other states. The islands have an extensive bilateral free trade agreement with Iceland, known as

6954-433: The Logan Stone. It is a Cornish tradition to make a vow and then attempt to move a rocking stone, or logan rock. It was said that no persons with treachery in their hearts could make a rocking stone move. Rock (geology) In geology , rock (or stone ) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition , and

7076-656: The Løgting were written in Faroese from 1927 onwards, schools switched to Faroese as the language of instruction in 1938, and Faroese was fully authorised as the language of the Church the following year. Finally in 1944, Faroese gained equal status with Danish in legal proceedings. In the first year of the Second World War , on 12 April 1940, British troops occupied the Faroe Islands in Operation Valentine . Nazi Germany had invaded Denmark and commenced

7198-621: The March Dyke, a rocking stone named the Logan Stone exists. The Logan Stone is a grey granite rock and rests on greywacke, and can easily be moved with one hand. It is 4 feet 3 inches (1.30 m) by 4 feet (1.2 m), by 3 feet (0.91 m) high. There is a famous pair of rocking stones on the Faroese island of Eysturoy in the village of Oyndarfjørður . These are known as the Rinkusteinar. Local legend states that an old sorceress cursed two pirate ships that were menacing

However, Mr. Davies Gilbert persuaded the Lords of the Admiralty to lend Lieutenant Goldsmith the required apparatus for replacing the Logan Rock. The Admiralty sent 13 capstans with blocks and chains from the dock yard at Plymouth , and contributed £25 towards expenses. Gilbert also raised more funds. After months of effort, at 4:20 pm on 2 November 1824, in front of thousands of spectators and with

Distance from the Faroe Islands to: The islands cover an area of 1,399 square kilometres (540 sq. mi) and have small lakes and rivers, but no major ones. There are 1,117 kilometres (694 mi) of coastline. The only significant uninhabited island

7686-552: The collapse of the fishing industry in the early 1990s, the Faroes experienced considerable economic difficulties. The Faroe Islands are an island group consisting of 18 major islands (and a total of 779 islands, islets , and skerries ) about 655 kilometres (407 mi) off the coast of Northern Europe, between the Norwegian Sea and the North Atlantic Ocean , about halfway between Iceland and Norway ,

7808-523: The constituent particles, and particle size . These physical properties are the result of the processes that formed the rocks. Over the course of time, rocks can be transformed from one type into another, as described by a geological model called the rock cycle . This transformation produces three general classes of rock: igneous , sedimentary and metamorphic . Those three classes are subdivided into many groups. There are, however, no hard-and-fast boundaries between allied rocks. By increase or decrease in

7930-405: The course of volcanism and the age sequence of the layers. There are major differences in the shapes of the islands' terraces. The lowest and oldest series are thick lava deposits that can be seen on the southern part of Suðuroy, Mykines and Tindhólmur and the western side of Vágar. The basalts of the lower basalt series are often pillared, which is shown by elongated, angular and regular pillars in

8052-449: The cove, and while watching ensuing activity, the employee leaned against a boulder. Suddenly, a gust of wind occurred, and the boulder shifted, or "logged". The longest side of this mass of stone is about 15 feet (4.6 m), and the circumference of its biggest end is about 20 feet (6.1 m). It is thought to weigh about 20 tons. A rocking stone is recorded near the site of Saint Bride's Chapel. The Witch's or Boarstone stands on top of

8418-496: The earliest humans. This early period, called the Stone Age , saw the development of many stone tools. Stone was then used as a major component in the construction of buildings and early infrastructure . Mining developed to extract rocks from the Earth and obtain the minerals within them, including metals . Modern technology has allowed the development of new human-made rocks and rock-like substances, such as concrete . Geology

A number of the settlers were Norse–Gaels who did not come directly from Scandinavia, but rather from Norse communities that spanned the Irish Sea , Northern Isles , and Outer Hebrides of Scotland , including the Shetland and Orkney islands; these settlers also brought thralls of Gaelic origin with them, and this admixture

8662-606: The earth's surface by the accumulation and cementation of fragments of earlier rocks, minerals, and organisms or as chemical precipitates and organic growths in water ( sedimentation ). This process causes clastic sediments (pieces of rock) or organic particles ( detritus ) to settle and accumulate or for minerals to chemically precipitate ( evaporite ) from a solution . The particulate matter then undergoes compaction and cementation at moderate temperatures and pressures ( diagenesis ). Before being deposited, sediments are formed by weathering of earlier rocks by erosion in

8784-427: The earth, from an ore body, vein or seam . The term also includes the removal of soil. Materials recovered by mining include base metals , precious metals , iron , uranium , coal , diamonds , limestone , oil shale , rock salt , potash , construction aggregate and dimension stone . Mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in

8906-402: The end of World War II , some of the population favoured independence from Denmark, and on 14 September 1946, an independence referendum was held on the question of secession . It was a consultative referendum, the parliament not being bound to follow the people's vote. This was the first time that the Faroese people had been asked whether they favoured independence or wanted to continue within

9028-490: The fewest recorded hours of sunshine of any city in the world at only 840 per year. While archaeological evidence places the first known habitation as early as the 4th century, Færeyinga Saga and the writings of Dicuil place initial Norse settlement in the early 9th century. As with the subsequent Settlement of Iceland , the islands were mainly settled by Norwegians and Norse-Gaels , who additionally brought thralls (i.e. slaves or serfs ) of Gaelic origin. Following

9150-403: The first terrace. Volcanic activity has varied over millions of years, with periods of quiescence and various periods of quiet eruptive fissures and explosive volcanism. In a few places, mainly on Suðuroy, thin layers of coal are present, which are the remains of swamp forests from the time between volcanic eruptions. The plateau has therefore been divided into different basalt series according to

9272-621: The formation of rocking stones. Several rocking stones, or stones that used to rock at one time, are there. A rocking stone that some associate with the Druids is on Cuff Hill in Hessilhead , near Beith in North Ayrshire . It no longer rocks due to people digging beneath to ascertain its fulcrum. It is in a small wood and surrounded by a circular drystone wall. An article was published in the Cumnock Chronicle in 1907 on

9394-402: The ground; pressure is dominant, and temperature plays a smaller role. This is termed burial metamorphism, and it can result in rocks such as jade . Where both heat and pressure play a role, the mechanism is termed regional metamorphism. This is typically found in mountain-building regions. Depending on the structure, metamorphic rocks are divided into two general categories. Those that possess

9516-459: The heights, often resulting in a characteristic curved landscape shape. This can be clearly seen on Vágar, the northernmost part of Streymoy and the north-western part of Eysturoy. Glacial activity has reduced plateau surfaces, especially on the northern islands, where the surfaces have been reduced to a series of narrower or wider zig-zag rows along the length of the islands: especially on the islands of Kunoy, Kalsoy and Borðoy, where an eastward and

9638-415: The help of more than 60 men and block and tackle, the Logan Rock was finally repositioned and returned to "rocking condition". Apparently, the total final cost of this enterprise was £130 8s 6d. However, it is not clear how much of the remaining £105 Goldsmith had to make up out of his own pocket. For some time after, the rock was kept chained and padlocked, but eventually these restrictions were removed, and

9760-591: The introduction of Christianity by Sigmundur Brestisson , the islands came under Norwegian rule in the early 11th century. The Faroe Islands followed Norway's integration into the Kalmar Union in 1397, and came under de facto Danish rule following that union's dissolution in 1523. Following the introduction of Lutheranism in 1538, the usage of Faroese was banned in churches, schools and state institutions, and disappeared from writing for more than three centuries. The islands were formally ceded to Denmark in 1814 by

9882-535: The invasion of Norway on 9 April 1940 under Operation Weserübung . In 1942–1943, the British Royal Engineers , under the command of lieutenant colonel William Law, built the first and only airport in the Faroe Islands, Vágar Airport . The British refrained from governing Faroese internal affairs, and the islands became effectively self-governing during the war. After the war ended and the British army left, this period and Iceland 's declaration as

10004-592: The island after the Ice Age, but disappeared later - apparently as a result of grazing impacts, possibly aggravated by a shift to relatively wetter cooler climatic conditions about the same time. A limited number of species have been successfully introduced to the region, in particular trees from the Magellanic subpolar forests region of Chile. Conditions in the Magellanic subpolar forests are similar to those in

10126-457: The islanders in accordance with longstanding local tradition. Orcas ( Orcinus orca ) are regular visitors around the islands. The domestic animals of the Faroe Islands are a result of 1,200 years of isolated breeding. As a result, many of the islands' domestic animals are found nowhere else in the world. Faroese domestic breeds include Faroe pony , Faroe cow , Faroe sheep, Faroese goose , and Faroese duck . The islands were built up during

10248-552: The islands coming under de facto Danish control. When the Protestant Reformation reached the Faroe Islands in 1538, the Faroese language was also outlawed in schools, churches and official documentation; thus Faroese remained exclusively a spoken language until the 19th century. Following the Napoleonic Wars , the union between Denmark and Norway was dissolved by the Treaty of Kiel in 1814; while Norway

10370-491: The kind of metals available from the rock of a region. Anthropic rock is synthetic or restructured rock formed by human activity. Concrete is recognized as a human-made rock constituted of natural and processed rock and having been developed since Ancient Rome . Rock can also be modified with other substances to develop new forms, such as epoxy granite . Artificial stone has also been developed, such as Coade stone . Geologist James R. Underwood has proposed anthropic rock as

10492-431: The land to prepare it for other uses once mining ceases. Mining processes may create negative impacts on the environment both during the mining operations and for years after mining has ceased. These potential impacts have led to most of the world's nations adopting regulations to manage negative effects of mining operations. Stone tools have been used for millions of years by humans and earlier hominids . The Stone Age

10614-475: The language to print after 300 years of only existing in oral form. With the return of written Faroese to the public sphere after more than 300 years, nationalism gained a foothold in Faroese society: the modern Faroese national movement is commonly agreed to have begun with the Christmas Meeting of 1888 , held to "discuss how to defend the Faroese language and Faroese traditions". This meeting led to

10736-419: The middle group near the top, lies a very large stone, so evenly, poised that any hand may move it to and fro; but the extremities of its base are at such a distance from each other, and so well secured by their nearness to the stone which it stretches itself upon, that it is morally impossible that any lever, or indeed force, however applied in a mechanical way, can remove it from its present situation. Goldsmith

10858-423: The mountain side. Very regular vertical columns are found on northern Mykines, where they can be up to 30 metres (100 ft) high. The middle basalt series consists of thin lava flows with a highly porous interlayer. This series has very little resistance to crumbling and weathering. As these erosion processes are more severe at higher altitudes than lower down, the lowlands are filled with weathering material from

10980-731: The mountains, although some coastal or low-lying areas may have very mild-winter versions of a tundra climate. The overall character of the climate of the islands is influenced by the strong warming influence of the Atlantic Ocean, which produces the North Atlantic Current . This, together with the remoteness of any source of landmass-induced warm or cold airflows, ensures that winters are mild (mean temperature 3.0 to 4.0 °C or 37 to 39 °F) while summers are cool (mean temperature 9.5 to 10.5 °C or 49 to 51 °F). The islands are windy, cloudy, and cool throughout

11102-488: The number of invalid votes (481) being greater than the narrow margin in favour made the result invalid. As a result, King Christian X of Denmark ordered that the Faroese Løgting be dissolved on 24 September, with new elections held that November. The Faroese parliamentary election of 1946 resulted in a majority for parties opposed to independence: following protracted negotiations, Denmark granted home rule to

11224-466: The old form. The name's ultimate etymological origin has been subject to dispute. The most widely-held theory, first attested in Færeyinga Saga , interprets it as a straightforward compound of fær ('sheep') and eyjar ('islands'), meaning "sheep islands", in reference to their abundance on the archipelago. Clergymen Peder Clausson and Lucas Debes began casting doubt on this theory in

11346-520: The opening of the North Atlantic ocean , which began about 60 million years ago, and what is today the Faroe Islands was then attached to Greenland. The lavas are underlain by circa 30 km of unidentified ancient continental crust. The climate is classed as subpolar oceanic climate according to the Köppen climate classification : Cfc , with areas having a tundra climate, especially in

11468-418: The original rock was formed. This process is called metamorphism , meaning to "change in form". The result is a profound change in physical properties and chemistry of the stone. The original rock, known as the protolith , transforms into other mineral types or other forms of the same minerals, by recrystallization . The temperatures and pressures required for this process are always higher than those found at

11590-425: The particles of clastic sedimentary rocks can be further classified by grain size . The smallest sediments are clay , followed by silt , sand , and gravel . Some systems include cobbles and boulders as measurements. Metamorphic rocks are formed by subjecting any rock type—sedimentary rock, igneous rock or another older metamorphic rock—to different temperature and pressure conditions than those in which

11712-466: The proportions of their minerals, they pass through gradations from one to the other; the distinctive structures of one kind of rock may thus be traced, gradually merging into those of another. Hence the definitions adopted in rock names simply correspond to selected points in a continuously graduated series. Igneous rock (derived from the Latin word igneus, meaning of fire, from ignis meaning fire)

11834-621: The reason for the stone being dislodged. The Ogrestone or Thurgartstone near Dunlop in East Ayrshire is thought to have been a rocking stone. However, soil has built up around the base of the Thurgatstone over the years, which now prevents any rocking motion. A rocking stone existed in 1913–1919 at Sannox on Arran, on a nearly horizontal platform next to the seashore. The Lamagee or Lamargle stone in Lugar as previously mentioned

11956-400: The rise of two of the movement's most prominent early figures: Jóannes Patursson and Rasmus Effersøe . It was initially exclusively concerned with the status of the Faroese language , but it soon gained a political dimension with the advent of the Faroese language conflict in the early 20th century. Both sides of the conflict were represented by the country's first-ever political parties:

12078-408: The rock was set free. However, it apparently no longer vibrates or "logs" as easily as it did before. Tourism dropped, and this was blamed on the condition of Logan Rock. For a while, Treen was nicknamed 'Goldsmith's Deserted Village '. Another famous rock structure, Lanyon Cromlech , was knocked down during a thunderstorm in 1815. The same machinery that was used to restore the Logan Rock in Treen

12200-648: The ruins of the Roman temples at Jerash in Jordan (the "city of 1000 pillars"), some massive pillars move back and forth in the slightest breeze. A stone used to rock on a gritstone outcrop on Warley Moor near Halifax in West Yorkshire. It had already ceased to rock when described by John Watson in 1775. Ayrshire in Southwest Scotland apparently is endowed with a geology that lends itself towards

12322-467: The sensation of rocking gently while seated upon the huge rock. The Pontypridd Rocking Stone in Wales is set within the middle of a Druidic stone circle. Bosistow Logan Rock is at the head of Pendower Cove (sometimes written as Pendour Cove) near Zennor , Cornwall. It apparently was discovered by an employee of the lord of the local manor whose duty it was to watch the coast. A ship had been wrecked in

12444-579: The term is still commonly used to indicate a geographical region. In earlier times, each sýsla had its own assembly , the so-called várting ("spring assembly"). The Faroe Islands have been under Norwegian-Danish control since 1388. The 1814 Treaty of Kiel terminated the Danish–Norwegian union, and Norway came under the rule of the King of Sweden , while the Faroe Islands, Iceland, and Greenland remained Danish possessions. From ancient times

12566-621: The universe's celestial bodies. In the Solar System , Mars , Venus , and Mercury are composed of rock, as are many natural satellites , asteroids , and meteoroids . Meteorites that fall to Earth provide evidence of extraterrestrial rocks and their composition. They are typically heavier than rocks on Earth. Asteroid rocks can also be brought to Earth through space missions, such as the Hayabusa mission. Lunar rocks and Martian rocks have also been studied. The use of rock has had

12688-479: The valley. A failed attempt to rescue the stone by pulling it back up the valley resulted in it breaking into pieces. Around 1900 there were rocking stones at Rippon tor, and Sittaford tor on Dartmoor. A 150-ton glacial erratic occurs on Rockingstone Avenue in Larchmont, New York, that was so perfectly balanced that just a small touch would allow it to rock back and forth. Unfortunately in the 1920s, blasting for

12810-629: The village, turning them to stone. A chain connected to the mainland makes it easier to see the rock's movements. Near Lugar in the Parish of Auchinleck in Ayrshire, Scotland, is the Lamargle or Lamargee rocking stone in a hollow by the Bello or Bellow Water near its junction with the Glenmore Water from which point the name Lugar Water is applied. It is made of two vertical stones, and a horizontal stone about 6 ft long, 3 ft broad, and 4 ft high. It

12932-590: The way in which it is formed. Rocks form the Earth's outer solid layer, the crust , and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere . The study of rocks involves multiple subdisciplines of geology, including petrology and mineralogy . It may be limited to rocks found on Earth, or it may include planetary geology that studies the rocks of other celestial objects. Rocks are usually grouped into three main groups: igneous rocks , sedimentary rocks and metamorphic rocks . Igneous rocks are formed when magma cools in

13054-480: The words feur ('pasture, eaten-up outfield') and fearann ('land, territory') as possible derivations, arguing that the original Celtic attestations of the islands made this more likely. Archaeologist Anton Wilhelm Brøgger concurred, elaborating on Watson's theory by positing that the Norse, having first learned of the islands from Scottish and Irish accounts as a fearann , could have coined Færeyjar as

13176-479: The world. A few rocking stones might be man-made megaliths . The word "logan" is probably derived from the word "log", which in an English dialect means to rock. In some parts of the United Kingdom, rocking stones or logan stones are called logging stones. The word "log" might be connected with the Danish word logre , which means to "wag a tail". Davies Gilbert suggested that the word "logan" comes from

13298-452: The year 500. Barley and sheep had to have been brought to the islands by humans; as Scandinavians did not begin using sails until about 750, it is unlikely they could have reached the Faroes before then, leading to the study concluding that the settlers were more likely to originate from Scotland or Ireland. These findings concur with historical accounts from the same period: archaeologist Mike Church noted that Irish monk Dicuil described

13420-400: The year with an average of 210 rainy or snowy days per year. The islands lie in the path of depressions moving northeast, making strong winds and heavy rain possible at all times of the year. Sunny days are rare and overcast days are common. Hurricane Faith struck the Faroe Islands on 5 September 1966 with sustained winds over 100 mph (160 km/h) and only then did the storm cease to be

13542-408: Was a period of widespread stone tool usage. Early Stone Age tools were simple implements, such as hammerstones and sharp flakes. Middle Stone Age tools featured sharpened points to be used as projectile points , awls, or scrapers . Late Stone Age tools were developed with craftsmanship and distinct cultural identities. Stone tools were largely superseded by copper and bronze tools following

13664-459: Was also seen as an inciting factor for the Settlement of Iceland . The founding date of the Løgting is not historically documented, though the saga implies that it was a well-established institution by the middle of the 10th century, when a legal dispute between chieftains Havgrímur and Einar Suðuroyingur, resulting in the exile of Eldjárn Kambhøttur, is recounted in detail. Christianity

13786-548: Was at Golcar Hill, near Halifax in Yorkshire. However, the Golcar Hill rocking stone will no longer easily rock because some masons wanted to find out how such a large weight could move so easily, so they chopped at it until they destroyed its balance. A very sensitive rocking stone called Men Amber (sometimes written as Men-Amber or Menamber) was on a high ridge in the parish of Sithney , near Pendennis , Cornwall. It

13908-604: Was defined particularly by Sigmundur's conflict with rival chieftain Tróndur í Gøtu , the latter of whom was converted under threat of decapitation. Although their conflict resulted in Sigmundur's murder, the Islands fell firmly under Norwegian rule following Tróndur's death in 1035. While the Faroe Islands formally remained a Norwegian possession until 1814, Norway 's merger into the Kalmar Union in 1397 gradually resulted in

14030-522: Was determined to demonstrate that nothing was impossible when the courage and skill of British seamen were engaged. The Logan Rock fell and was caught in a narrow chasm. This upset the local residents considerably, since Logan Rock had been used to draw tourists to the area. Sir Richard Vyvyan (1800–1879) was particularly unhappy. They demanded that the British Admiralty strip Lieutenant Goldsmith of his Royal Navy commission unless he restored

14152-765: Was dislodged because: Another well-known example of a rocking or logan stone is Logan Rock of Treen in Cornwall. This huge stone weighs about 80 or 90 tons. It is one of the best-known rocking stones for several reasons. For example, Modred, in William Mason 's dramatic poem " Caractacus " addressing the characters Vellinus and Elidurus, says of the Logan Rock: Thither, youths, Turn your astonish'd eyes; behold yon huge And unhewn sphere of living adamant, Which, poised by magic, rests its central weight On yonder pointed rock: firm as it seems, Such

14274-456: Was formed. Most rocks contain silicate minerals , compounds that include silica tetrahedra in their crystal lattice , and account for about one-third of all known mineral species and about 95% of the earth's crust . The proportion of silica in rocks and minerals is a major factor in determining their names and properties. Rocks are classified according to characteristics such as mineral and chemical composition, permeability , texture of

14396-543: Was introduced to the islands in the late 10th and early 11th centuries by chieftain Sigmundur Brestisson . Baptised as an adult by then- King of Norway Olaf Tryggvason , his mission to introduce Christianity was part of a greater plan to seize the islands on behalf of the Norwegian crown. While Christianity arrived at the same time as in Iceland , the process was met with much more conflict and violence, and

14518-789: Was quarried for construction as early as 4000 BCE in Egypt, and stone was used to build fortifications in Inner Mongolia as early as 2800 BCE. The soft rock, tuff , is common in Italy, and the Romans used it for many buildings and bridges. Limestone was widely used in construction in the Middle Ages in Europe and remained popular into the 20th century. Mining is the extraction of valuable minerals or other geological materials from

14640-645: Was regarded as a Druidic monument or the grave of a Caledonian hero. This stone has often been overlooked, as the OS maps give the wrong location; it sits beside the Bellow Water above its confluence with the Glenmore Water and not on Lamargle Hill. The Kyaiktiyo Pagoda in Burma is a religious shrine built on top of a huge granite boulder that is also a rocking stone. Some masses shaped by humans also exhibit similar behaviour (sometimes unintentionally). For example, in

14762-422: Was successful in repositioning Lanyon Cromlech. A wide variety of beliefs are associated with rocking stones. Because of their strange nature, rocking stones were sometimes associated with witchcraft , or Druids . The rocking stone near Nancledrea in Cornwall was said to only move at midnight when witches were out. People claimed that if one touched the rocking stone nine times at midnight, one would turn into

14884-542: Was transferred to the Swedish Crown, Denmark retained possession of Norway's North Atlantic territories, which included the Faroe Islands along with Greenland and Iceland. Shortly afterwards, Denmark asserted control and began to restrict the islands' autonomy. In 1816, the Faroe Islands was reconstituted as a county ( amt ) within the Danish Kingdom : the Løgting , having operated continuously for almost
