26-719: The Ellsworth Mountains are the highest mountain ranges in Antarctica , forming a 350 km (217 mi) long and 48 km (30 mi) wide chain of mountains in a north to south configuration on the western margin of the Ronne Ice Shelf in Marie Byrd Land . They are bisected by Minnesota Glacier to form the Sentinel Range to the north and the Heritage Range to the south. The former

52-402: A mountainous region, elevated mountainous plateau or high hills . Generally, upland refers to a range of hills, typically from 300 m (980 ft) up to 600 m (2,000 ft), while highland is usually reserved for ranges of low mountains . However, the two terms are interchangeable and also include regions that are transitional between hilly and mountainous terrain. Probably

78-538: Is at work while the mountains are being uplifted until the mountains are reduced to low hills and plains. The early Cenozoic uplift of the Rocky Mountains of Colorado provides an example. As the uplift was occurring some 10,000 feet (3,000 m) of mostly Mesozoic sedimentary strata were removed by erosion over the core of the mountain range and spread as sand and clays across the Great Plains to

104-617: Is by far the higher and more spectacular with Mount Vinson (4,892 meters (16,050 ft)) constituting the highest point on the continent. The mountains are located within the Chilean Antarctic territorial claim but outside of the Argentinian and British ones. The mountains were discovered on November 23, 1935, by the American explorer Lincoln Ellsworth in the course of a trans-Antarctic flight from Dundee Island to

130-613: Is the Central Highlands area, which covers most of the central-western parts of the state. Many of these areas are highly elevated alpine regions. The Ozarks cover nearly 120,000 square kilometres (46,000 sq mi), making it the most extensive highland region between the Appalachians and Rockies. This region contains some of the oldest rocks in North America. The spine of the mountains stretches across

156-865: The Alpide belt . The Pacific Ring of Fire includes the Andes of South America, extends through the North American Cordillera , the Aleutian Range , on through Kamchatka Peninsula , Japan , Taiwan , the Philippines , Papua New Guinea , to New Zealand . The Andes is 7,000 kilometres (4,350 mi) long and is often considered the world's longest mountain system. The Alpide belt stretches 15,000 km across southern Eurasia , from Java in Maritime Southeast Asia to

182-551: The Annamite Range . If the definition of a mountain range is stretched to include underwater mountains, then the Ocean Ridge forms the longest continuous mountain system on Earth, with a length of 65,000 kilometres (40,400 mi). The position of mountain ranges influences climate, such as rain or snow. When air masses move up and over mountains, the air cools, producing orographic precipitation (rain or snow). As

208-804: The Iberian Peninsula in Western Europe , including the ranges of the Himalayas , Karakoram , Hindu Kush , Alborz , Caucasus , and the Alps . The Himalayas contain the highest mountains in the world, including Mount Everest , which is 8,848 metres (29,029 ft) high. Mountain ranges outside these two systems include the Arctic Cordillera , Appalachians , Great Dividing Range , East Siberians , Altais , Scandinavians , Qinling , Western Ghats , Vindhyas , Byrrangas , and

234-606: The Mithrim Montes and Doom Mons on Titan, and Tenzing Montes and Hillary Montes on Pluto. Some terrestrial planets other than Earth also exhibit rocky mountain ranges, such as Maxwell Montes on Venus taller than any on Earth and Tartarus Montes on Mars . Jupiter's moon Io has mountain ranges formed from tectonic processes including the Boösaule , Dorian, Hi'iaka and Euboea Montes . Highland Highlands or uplands are areas of high elevation such as

260-517: The Ross Ice Shelf . He gave them the descriptive name Sentinel Range. The mountains were mapped in detail by the U.S. Geological Survey from ground surveys and U.S. Navy aerial photography, 1958–1966. When it became evident that the mountains comprise two distinct ranges, the US-ACAN restricted the application of Sentinel Range to the high northern one and gave the name Heritage Range to

286-655: The United States (notably Western North Carolina ), highveld , used in South Africa and Roof of the World , used for Tibet . The central Afghan highlands are in the center of Afghanistan , mostly located between 2,000 and 3,000 m above sea level. They have a very cold winter, and a short and cool summer. These highlands have mountain pastures during summer ( sardsīr ), watered by many small streams and rivers. There are also pastures available during winter in

312-794: The 1,000 meters (3,300 ft) thick Permian Polarstar Formation consisting of black argillite , siltstone , sandstone , and coal. Within the Heritage Group is the Union Glacier Formation of ashflow tuff - lahar deposits, the Hyde Glacier Formation of graywacke -argillite-conglomerate, the Drake Icefall Formation of black shales and marble, the Conglomerate Ridge Formation of conglomerate and quartzite ,

338-583: The Ellsworth Mountains average around -30 °C (-20 °F). The best time for expeditions are November through January, mid-summer in the Southern Hemisphere . Arranging an outing here is a difficult task, requiring either official scientific sponsorship or considerable financial resources. Mountain range Mountain ranges are usually segmented by highlands or mountain passes and valleys . Individual mountains within

364-932: The Liberty Hills-Springer Peak-Frazier Ridge Formations of quartzite-argillite, and the Minaret Formation of marble. Within the Crashsite Group is the Howard Nunataks Formation of quartzites, the Mt. Liptak Formation of quartzites, and the Mount Wyatt Earp Formation of quartzites. Major deformation of the sedimentary rocks occurred during the Gondwanide orogeny , followed by later uplift . The temperatures in

390-1136: The United Kingdom include the Southern Uplands in Scotland, the Pennines , North York Moors , Dartmoor and Exmoor in England , and the Cambrian Mountains in Wales . Many countries and regions also have areas referred to as highlands . These include parts of Afghanistan , Tibet , Ethiopia , Canada , Kenya , Eritrea , Yemen , Ghana , Nigeria , Papua New Guinea , Syria , Turkey and Cantabria . Similar terms used in other countries include high country , used in New Zealand , New South Wales , Victoria , Tasmania and Southern Queensland in Australia , and parts of

416-627: The air descends on the leeward side, it warms again (following the adiabatic lapse rate ) and is drier, having been stripped of much of its moisture. Often, a rain shadow will affect the leeward side of a range. As a consequence, large mountain ranges, such as the Andes, compartmentalize continents into distinct climate regions . Mountain ranges are constantly subjected to erosional forces which work to tear them down. The basins adjacent to an eroding mountain range are then filled with sediments that are buried and turned into sedimentary rock . Erosion

442-678: The best-known area officially or unofficially referred to as highlands in the Anglosphere is the Scottish Highlands in northern Scotland , the mountainous region north and west of the Highland Boundary Fault . The Highland council area is a local government area in the Scottish Highlands and Britain's largest local government area. Other highland or upland areas reaching 400 m or higher in

468-485: The east. This mass of rock was removed as the range was actively undergoing uplift. The removal of such a mass from the core of the range most likely caused further uplift as the region adjusted isostatically in response to the removed weight. Rivers are traditionally believed to be the principal cause of mountain range erosion, by cutting into bedrock and transporting sediment. Computer simulation has shown that as mountain belts change from tectonically active to inactive,

494-653: The endemic vertebrates are restricted to this ecoregion. The highlands of Iceland cover about 40% of the country and are mostly inhospitable to humans. They are generally considered to be any land above 500 m. The mountainous natural region of the Thai highlands is found in Northern Thailand. The Cameron Highlands is a highland area and hill station in Northern Malaysia. Shillong in India in

The Central Highlands of Sri Lanka are rain forests, where the elevation reaches 2,500 m (8,200 ft) above sea level. The Sri Lanka montane rain forests represent the montane and submontane moist forests above 1,000 m (3,300 ft) in the central highlands and in the Knuckles mountain range . Half of Sri Lanka's endemic flowering plants and 51 percent of

546-575: The neighboring warm lowlands ( garmsīr ), which makes the region ideal for seasonal transhumance . The highlands in Australia are often above the elevation of 500 m. These areas often receive snowfall in winter. Most of the highlands lead up to large alpine or sub-alpine mountainous regions such as the Australian Alps , Snowy Mountains , Great Dividing Range , Northern Tablelands and Blue Mountains . The most mountainous region of Tasmania

572-627: The rate of erosion drops because there are fewer abrasive particles in the water and fewer landslides. Mountains on other planets and natural satellites of the Solar System, including the Moon , are often isolated and formed mainly by processes such as impacts, though there are examples of mountain ranges (or "Montes") somewhat similar to those on Earth. Saturn 's moon Titan and Pluto , in particular, exhibit large mountain ranges in chains composed mainly of ices rather than rock. Examples include

598-531: The same mountain range do not necessarily have the same geologic structure or petrology . They may be a mix of different orogenic expressions and terranes , for example thrust sheets , uplifted blocks , fold mountains, and volcanic landforms resulting in a variety of rock types . Most geologically young mountain ranges on the Earth's land surface are associated with either the Pacific Ring of Fire or

624-622: The southern one; the Committee recommended the name of the discoverer for this entire group of mountains. Geologically, the Ellsworth Mountains occupy a discrete block of continental crust known as the Ellsworth-Whitmore Mountain terrane. This terrane was part of the early Paleozoic amalgamation of Gondwana and consists of a 13,000 meters (43,000 ft) thick section of folded Cambrian – Permian strata , which accumulated on Grenville -age continental crust. It

650-535: The state of Meghalaya is a hill station that is surrounded by highlands. Officers of the British Raj referred to Shillong as "The Scotland of the East". Highland continents —or terrae —are areas of topographically unstable terrain , with high peaks and valleys. They resemble highlands on Earth , but the term is applied to much larger areas on other planets. They can be found on Mercury , Venus , Mars , and

676-578: Was likely once part of the Cape Fold Belt that was detached from southern Africa during the breakup of Gondwana and later incorporated into Antarctica. The stratigraphy consists of the 7,500 meters (24,600 ft) thick Early Cambrian - Middle Cambrian Heritage Group overlain by the 3,000 meters (9,800 ft) thick Late Cambrian - Devonian Crashsite Group; the 1,000 meters (3,300 ft) thick Permo-Carboniferous Whiteout Conglomerate (black diamictite ) from Gondawanaland glaciation; and
