As the Sun is the major contributor to the temperature, it is often directly proportional to the received radiation from the Sun with faces receiving more sunlight having a higher heat buildup. In narrow valleys between steep mountain faces, the weather conditions may differ significantly on both
1071-495: A notable increase in the rate of glacier retreat across the region as a result of climate change. The rate of retreat varies across regions depending on the local conditions. Since 1975, a marked increase in the loss of glacial mass from 5–13 Gt/yr to 16–24 Gt/yr has been observed with an estimated 13% overall decrease in glacial coverage in the Himalayas. The resulting climate variations and changes in hydrology could affect

In other Indic scripts, it is generally preferred to use a ligature or a half form to write a syllable or a cluster containing a dead consonant, although writing it with a visible virama is also possible. The Tamil script does not differentiate voiced and unvoiced plosives . Instead, plosives are articulated with voice depending on their position in a word, in accordance with the rules of Tamil phonology . In addition to

It uses diacritics to map the much larger set of Brahmic consonants and vowels to Latin script , and thus the alphabets of various languages, including English. Apart from the usual numerals, Tamil has numerals for 10, 100 and 1000. Symbols for day, month, year, debit, credit, as above, rupee, and numeral are present as well. Tamil also uses several historical fractional signs. /f/ , /z/ , /ʂ/ and /ɕ/ are only found in loanwords and may be considered marginal phonemes, though they are traditionally not seen as fully phonemic. Tamil has two diphthongs : /aɪ̯/ ஐ and /aʊ̯/ ஔ ,

In Malaysia, 543 primary education government schools are available fully in Tamil as the medium of instruction . The establishment of Tamil-medium schools has been in process in Myanmar to provide education completely in Tamil language by
11169-420: The Indian state of Tamil Nadu and one of the 22 languages under schedule 8 of the constitution of India . It is one of the official languages of the union territories of Puducherry and the Andaman and Nicobar Islands . Tamil is also one of the official languages of Singapore . Tamil is one of the official and national languages of Sri Lanka, along with Sinhala . It was once given nominal official status in
11322-606: The Sutlej River in the east to the Kali River in the west. The region comprises parts of Sivalik and Great Himalayas. At lower elevations below 2,400 m (7,900 ft), the region has a temperate climate and consists of permanent settlements. At elevations higher than 4,300 m (14,100 ft), permanent snow caps cover the Great Himalayas with the highest peaks being Nanda Devi at 7,817 m (25,646 ft) and Kamet at 7,756 m (25,446 ft). The region
11475-675: The Tamil kingdoms are in inscriptions from the 3rd century BCE during the time of the Maurya Empire. The Chola dynasty ruled from before the Sangam period (~3rd century BCE) until the 13th century in central Tamil Nadu. The heartland of the Cholas was the fertile valley of the Kaveri . The Pandyan dynasty ruled parts of South India until the late 17th century. The heartland of the Pandyas was
11628-590: The Tamil language, Kannada still preserves a lot from its roots. As part of the southern family of Indian languages and situated relatively close to the northern parts of India, Kannada also shares some Sanskrit words, similar to Malayalam. Many of the formerly used words in Tamil have been preserved with little change in Kannada. This shows a relative parallel to Tamil, even as Tamil has undergone some changes in modern ways of speaking. According to Hindu legend, Tamil or in personification form Tamil Thāi (Mother Tamil)
11781-696: The Tamils who settled there 200 years ago. Tamil language is available as a course in some local school boards and major universities in Canada and the month of January has been declared "Tamil Heritage Month" by the Parliament of Canada . Tamil enjoys a special status of protection under Article 6(b), Chapter 1 of the Constitution of South Africa and is taught as a subject in schools in KwaZulu-Natal province. Recently, it has been rolled out as
11934-530: The Tethys ocean. The upliftment of the Himalayas occurred gradually and as the Great Himalayas became higher, they became a climatic barrier and blocked the winds, which resulted in lesser precipitation on the upper slopes. The lower slopes continued to be eroded by the rivers, which flowed in the gaps between the mountains and the folded lower Shivalik Hills and the Lesser Himalayas were formed due to
12087-605: The Tibetan Himalayas and the plateau beyond. It also played a role in the formation of Central Asian deserts such as the Taklamakan and Gobi . The monsoon is triggered by the different rates of heating and cooling between the Indian Ocean and Central Asia, which create large differences in the atmospheric pressure prevailing above each. As the Central Asian landmass heats up during the summer compared to
12240-534: The Western Himalayas. The high altitude mountainous areas are mostly barren or, at the most, sparsely sprinkled with stunted bushes. The Himalayas are home to various medicinal plants such as Abies pindrow used to treat bronchitis , Andrachne cordifolia used for snake bites , and Callicarpa arborea used for skin diseases . Nearly a fifth of the plant species in the Himalayas are used for medicinal purposes. Climate change , illegal deforestation , and introduction of non native species have had an effect on
12393-716: The ancient definition. The ancient Tamilakam thus included the present-day Kerala . However, it excluded the present-day Tamil-inhabited territory in the North-East of Sri Lanka . From around 600 BCE to 300 CE, Tamiḻakam was ruled by the three Tamil dynasties: the Chola dynasty , the Pandyan dynasty and the Chera dynasty . There were also a few independent chieftains, the Velirs ( Satyaputra ). The earliest datable references to
12546-442: The ancient language ( sankattamiḻ ), a modern literary and formal style ( centamiḻ ), and a modern colloquial form ( koṭuntamiḻ ). These styles shade into each other, forming a stylistic continuum. For example, it is possible to write centamiḻ with a vocabulary drawn from caṅkattamiḻ , or to use forms associated with one of the other variants while speaking koṭuntamiḻ . In modern times, centamiḻ
12699-455: The animal species found in the region are unique and endemic or nearly endemic to the region. Other large animal species found in the Himalayas include Asiatic black bear , clouded leopard , and herbivores such as bharal , Himalayan tahr , takin , Himalayan serow , Himalayan musk deer , and Himalayan goral . Animals found at higher altitudes include brown bear , and the elusive snow leopard , which mainly feed on bharal. The red panda
12852-720: The bend of the Indus River along the Pakistan-Afghanistan border region in the north-west to the Satlej river basin in India in the south-east. Most of the region lies in the Kashmir territory disputed between India and Pakistan with certain portions of the Indian state of Himachal Pradesh . The Indus forms the division between the Western Himalayas and the Karakoram range to the north. The Western Himalayas include
13005-510: The cold winds from Central Asia , and plays a significant roles in influencing the monsoons . The vast size, varying altitude range, and complex topography of the Himalayas result in a wide range of climates, from humid and subtropical to cold and dry desert conditions. The mountains have profoundly shaped the cultures of South Asia and Tibet . Many Himalayan peaks are considered sacred across various Indian and Tibetan religions such as Hinduism , Buddhism , Jainism , and Bon . Hence,
13158-453: The condensation occurs at higher altitudes in the north, there is more precipitation in the Great Himalayas in the west during the winter rains and the precipitation reduces towards the east. In January, the Kumaon region receives about 3 in (76 mm) of rainfall compared to about 1 in (25 mm) in the Eastern Himalayas. The Himalayan region has a highly sensitive ecosystem and
13311-689: The culture associated with the Neolithic complexes of South India, but it has also been related to the Harappan civilization . Scholars categorise the attested history of the language into three periods: Old Tamil (300 BCE–700 CE), Middle Tamil (700–1600) and Modern Tamil (1600–present). About of the approximately 100,000 inscriptions found by the Archaeological Survey of India in India are in Tamil Nadu. Of them, most are in Tamil, with only about 5 percent in other languages. In 2004,
13464-952: The dialect of Madurai , and iṅkaṭe in some northern dialects. Even now, in the Coimbatore area, it is common to hear " akkaṭṭa " meaning "that place". Although Tamil dialects do not differ significantly in their vocabulary, there are a few exceptions. The dialects spoken in Sri Lanka retain many words and grammatical forms that are not in everyday use in India, and use many other words slightly differently. Tamil dialects include Central Tamil dialect , Kongu Tamil , Madras Bashai , Madurai Tamil , Nellai Tamil , Kumari Tamil in India ; Batticaloa Tamil dialect , Jaffna Tamil dialect , Negombo Tamil dialect in Sri Lanka; and Malaysian Tamil in Malaysia. Sankethi dialect in Karnataka has been heavily influenced by Kannada . The dialect of
13617-399: The differences between Tamil and Malayalam demonstrate a pre-historic divergence of the western dialect, the process of separation into a distinct language, Malayalam, was not completed until sometime in the 13th or 14th century. Additionally Kannada is also relatively close to the Tamil language and shares the format of the formal ancient Tamil language. While there are some variations from
13770-647: The district of Palakkad in Kerala has many Malayalam loanwords, has been influenced by Malayalam's syntax, and has a distinctive Malayalam accent. Similarly, Tamil spoken in Kanyakumari District has more unique words and phonetic style than Tamil spoken at other parts of Tamil Nadu. The words and phonetics are so different that a person from Kanyakumari district is easily identifiable by their spoken Tamil. Hebbar and Mandyam dialects, spoken by groups of Tamil Vaishnavites who migrated to Karnataka in
13923-475: The downwarping of the intermediate lands. Minor streams ran between the faults within the mountains until they joined the major river systems in the plains. Intermediate valleys such as Kashmir and Kathmandu were formed from temporary lakes that were formed during pleistocene , which dried up later. The Himalayan region is made up of five geological zones– the Sub-Himalayan Zone bound by
14076-482: The early historic period of South India . Tamiḻakam was divided into political regions called Perunadu or "Great country" ("nadu" means country). There were three important political regions which were Chera Nadu , Chola Nadu and Pandya Nadu . Alongside these three, there were two more political regions of Athiyaman Nadu (Sathyaputha) and Thamirabharani Nadu (Then Paandi) which were later on absorbed into Chera and Pandya Nadu by 3rd century BCE. Tondai Nadu which
14229-508: The eastern Assam Himalayas. The Nepal Himalayas forms the centre of the Himalayan curve and extend for 800 km (500 mi) between the Kali and Teesta Rivers . The Great Himalayas in the region form the highest part of the entire Himalayas and consist of many of the eight-thousanders including Everest, Kanchenjunga at 8,586 m (28,169 ft), and Makalu at 8,463 m (27,766 ft). These mountains host large glaciers that form
14382-495: The ecosystem. At higher altitudes, Eastern and Western Himalayan subalpine conifer forests consisting of various conifers occur. Chir pine is the dominant species which occurs at elevations from 800–900 m (2,600–3,000 ft). Other species include Deodar cedar , which grows at altitudes of 1,900–2,700 m (6,200–8,900 ft), blue pine and morinda spruce between 2,200–3,000 m (7,200–9,800 ft). At higher altitudes, alpine shrubs and meadows occur above
14535-630: The fertile valley of the Vaigai River . They initially ruled their country from Korkai , a seaport on the southernmost tip of the Indian Peninsula, and in later times moved to Madurai . The Chera dynasty ruled from before the Sangam period (~3rd century) until the 12th century over an area corresponding to modern-day western Tamil Nadu and Kerala . The Vealirs ( Vēḷir ) were minor dynastic kings and aristocratic chieftains in Tamiḻakam in
14688-417: The flora and fauna of the region. Changes might decrease the territory available for local wildlife and reduction in prey for the predators . This puts the animals in conflict with humans as humans might encroach animal territories and the animals might venture into human habitats for search of food, which might exacerbate the economic loss of the local population. The Himalayan nations are signatories of
14841-521: The flora of the range. The increase in temperature has resulted in shifting of various species to higher elevations, and early flowering and fruiting. Many of the animal species are from the tropics, which have adapted to the various conditions across the Himalayan range. Some of the species of the Eastern Himalayas are similar to those found in East and South East Asia , while the animals of
14994-405: The formation of the Tibetan plateau . During miocene (20 mya), the increasing collision between the plates resulted in the top layer of metamorphic rocks getting peeled, which moved southwards to form nappes with trenches in between. As the mountains received rainfall, the waters flowing down the mountains eroded and steepened the southern slopes. The silt deposited by these rivers and streams in
15147-699: The hill country . Tamil or dialects of it were used widely in the state of Kerala as the major language of administration, literature and common usage until the 12th century CE. Tamil was also used widely in inscriptions found in southern Andhra Pradesh districts of Chittoor and Nellore until the 12th century CE. Tamil was used for inscriptions from the 10th through 14th centuries in southern Karnataka districts such as Kolar , Mysore , Mandya and Bengaluru . There are currently sizeable Tamil-speaking populations descended from colonial-era migrants in Malaysia , Singapore , Philippines , Mauritius , South Africa , Indonesia, Thailand, Burma , and Vietnam . Tamil
15300-432: The introduction of new aspectual auxiliaries and more complex sentence structures, and with the emergence of a more rigid word order that resembles the syntactic argument structure of English. In 1578, Portuguese Christian missionaries published a Tamil prayer book in old Tamil script named Thambiran Vanakkam , thus making Tamil the first Indian language to be printed and published. The Tamil Lexicon , published by
15453-456: The last ice age , and give rise to some of the world's major rivers such as the Indus , Ganges , and Tsangpo – Brahmaputra . Their combined drainage basin is home to nearly 600 million people including 52.8 million living in the vicinity of the Himalayas. The region is also home to many endorheic lakes. The Himalayas have a major impact on the climate of the Indian subcontinent. It blocks
15606-461: The latter of which is restricted to a few lexical items. Tamil employs agglutinative grammar, where suffixes are used to mark noun class , number , and case , verb tense and other grammatical categories. Tamil's standard metalinguistic terminology and scholarly vocabulary is itself Tamil, as opposed to the Sanskrit that is standard for most Indo-Aryan languages . Much of Tamil grammar
15759-458: The livelihoods of the people in the Himalayas and the plains below. Despite its greater size, the Himalayas does not form a water divide across its span because of the multiple river systems that cut across the range. While the mountains were formed gradually, the rivers concurrently cut across deeper gorges ranging from 1,500–5,000 m (4,900–16,400 ft) in depth and 10–50 km (6.2–31.1 mi) in width. The actual water divide lies to
15912-590: The lower ranges on the southern slopes speak Indo-European languages. The inhabitants of the Western Himalayas include the Kashmiri people , who speak Kashmiri in the Vale of Kashmir and the Gujjar and Gaddi people , who speak Gujari and Gaddi respectively in the lower altitudes of Jammu and Himachal Pradesh in India. The last two are pastoral and nomadic people, who own flocks of cattle and migrate across
16065-468: The lowlands and grassland meadows in the mid altitudes. The composition and texture of the soils in the Himalayas also vary across regions. In the Eastern Himalayas , the wet soils has a high humus content conducive for growing tea . Podzolic soils occur in the eastern range of the Indus basin between the Indus and Shyok Rivers . The Ladakh region is generally dry with saline soil while fertile alluvial soils occur in select river valleys such as
16218-419: The main valley glaciers were 60–112 km (37–70 mi) long during the ice age. The glacier snowline (the altitude where accumulation and ablation of a glacier are balanced) was about 1,400–1,660 m (4,590–5,450 ft) lower than it is today. Thus, the climate would have been at least 7.0–8.3 °C (12.6–14.9 °F) colder than it is today. Since the late 20th century, scientists have reported
16371-411: The majority of the languages belonging to the first two categories. The Tibetan Himalayas are inhabited by Tibetan people , who speak Tibeto-Burman languages. The Great Himalayas are mostly inhabited by nomadic groups and tribes, with most of the population in Lesser Himalayas , and Shivalik Hills . People towards the Great Himalayas in the north parts mostly speak Tibeto-Burman, while populations in
16524-404: The margins. The mountains act as heat islands and heavier mountains absorb and retain more heat than the surroundings, and therefore influences the amount of heat needed to raise the temperature from the winter minimum to the summer maximum. However, soil temperatures mostly remain the same on both the sides of a mountain at altitudes higher than 4,500 m (14,800 ft). Temperatures in
16677-433: The most ancient term used for designating the Tamil territory. The earliest sources to mention it include Purananuru 168.18 and Patiṟṟuppattu Patikam 2.5. The Specific Preface ( cirappuppayiram ) of the more ancient text Tolkāppiyam mentions the terms tamil-kuru nal-lulakam ("the beautiful world [where] Tamil is spoken") and centamil ... nilam ("the territory ... of refined Tamil"). However, this preface, which
16830-423: The name comes from tam-miḻ > tam-iḻ "self-speak", or "our own speech". Kamil Zvelebil suggests an etymology of tam-iḻ , with tam meaning "self" or "one's self", and " -iḻ " having the connotation of "unfolding sound". Alternatively, he suggests a derivation of tamiḻ < tam-iḻ < * tav-iḻ < * tak-iḻ , meaning in origin "the proper process (of speaking)". However, this
16983-586: The north of the Himalayas with rivers flowing down both the sides of the mountains. Some of the major river systems and their drainage system outdate the formation of the mountains itself. The water divide is formed by the Karakoram and Hindu Kush ranges on the west and the Ladakh Range on the east, separating the Indus system from Central Asia. On the east, Kailas and Nyenchen Tanglha Mountains separate
17136-499: The north to the oceans at the cape in the south. In this region of cool waters were the four great cities of: Madurai with its towers; Uraiyur which was famous; tumultuous Kanchi ; and Puhar with the roaring waters [of the Kaveri and the ocean]. While these ancient texts do not clearly define the eastern and western boundaries of the Tamilakam, scholars assume that these boundaries were the seas, which may explain their omission from
17289-432: The northern kings Ashoka and Kharavela , also allude to the distinct identity of the region. For example, Ashoka's inscriptions refer to the independent states lying beyond the southern boundary of his kingdom, and Kharavdela's Hathigumpha inscription refers to the destruction of a "confederacy of Tamil powers". During the protohistoric period (1000-500 BCE) Sri Lanka was culturally united with southern India, and shared
17442-750: The northwest, which extend into Central Asia . Its western anchor Nanga Parbat lies south of the northernmost bend of the Indus river in Pakistan-administered Kashmir and its eastern anchor Namcha Barwa lies to the west of the great eastern bend of the Yarlung Tsangpo River in Tibet Autonomous Region of China . The Himalayas occupies an area of 595,000 km (230,000 sq mi) across six countries – Afghanistan , Bhutan , China, India , Nepal , and Pakistan . The sovereignty of
17595-436: The number of glacial lakes , some of which may be prone to dangerous floods. The region is expected to encounter continued increase in average annual temperature and 81% of the region's permafrost is projected to be lost by the end of the century. The increased warming and melting of snow is projected to accelerate the regional river flows until 2060 after which it would decline due to reduction in ice caps and glacier mass. As
17748-403: The ocean below, the difference in pressure creates a thermal low . The moist air from the ocean is pushed inwards towards the low pressure system causing the monsoon winds. It results in precipitation along the slopes due to the orographic effect as the air rises along the mountains and condenses. The monsoon begins at the end of May in the eastern fringes of the range and moves upwards towards
17901-537: The old aspect and time markers. The Nannūl remains the standard normative grammar for modern literary Tamil, which therefore continues to be based on Middle Tamil of the 13th century rather than on Modern Tamil. Colloquial spoken Tamil, in contrast, shows a number of changes. The negative conjugation of verbs, for example, has fallen out of use in Modern Tamil – instead, negation is expressed either morphologically or syntactically. Modern spoken Tamil also shows
18054-477: The past half a century. The average warm days and nights had also increased by 1.2 days and 1.7 nights per decade while the average cold days and nights had declined by 0.5 and 1 respectively. This has also prolonged the length of the growing season by 4.25 days per decade. The climate change might results in erratic rainfall, varying temperatures, and natural disasters like landslides , and floods . The increasing glacier melt had been followed by an increase in
18207-603: The precipitation is projected to increase concurrently, the annual river flows would be largely unaffected for the Eastern Himalayan rivers fed by monsoons, but would reduce the flows in the Western Himalayan rivers. Almost a billion people live on either side of the mountain and are prone to impact of the climate change. This includes the people who live in the mountains, who are more vulnerable due to temperature variations and other biota. Countries in
18360-469: The range in the Kashmir region is disputed among India, Pakistan, and China. It is bordered by the Karakoram and Hindu Kush ranges on the northwest, Tibetan Plateau in the north, and by the Indo-Gangetic Plain in the south. Its western anchor Nanga Parbat lies south of the northernmost bend of the Indus river and its eastern anchor Namcha Barwa lies to the west of the great bend of
18513-462: The range in the Kashmir region is disputed amongst India, Pakistan, and China. The range varies in width from 350 km (220 mi) in the north-west to 150 km (93 mi) in the south-east. The range has several peaks exceeding an elevation of 8,000 m (26,000 ft) including Mount Everest , the highest mountain on Earth at 8,848 m (29,029 ft). The Himalayas consist of four parallel mountain ranges from south to north:
18666-1034: The region tropical and subtropical , temperate , coniferous , and grasslands . Tropical and subtropical broadleaf forests are mostly constricted to the high temperature and humid regions in Eastern and Central Himalayas , and pockets of Kashmir in the west. There are about 4,000 species of Angiosperms with major vegetation include Dipterocarpus , and Ceylon ironwood on porous soils at elevations below 2,400 m (7,900 ft) and oak , and Indian horse chestnut on lithosol between 1,100–1,700 m (3,600–5,600 ft). Himalayan subtropical pine forests with Himalayan screw pine trees occur above 4,000 m (13,000 ft) and Alder , and bamboo are found on terrains with higher gradient. Temperate forest occur at altitudes between 1,400–3,400 m (4,600–11,200 ft) while moving from south-east to north-west towards higher latitude. Eastern and Western Himalayan broadleaf forests consisting of sal trees dominate
18819-777: The region. More than 800 species of birds have been recorded with a large number of species restricted to the Eastern Himalayas. Amongst the bird species found include magpies such as black-rumped magpie and blue magpie , titmice , choughs , whistling thrushes , and redstarts . Raptors include bearded vulture , black-eared kite , and Himalayan griffon . Snow partridge and Cornish chough are found at altitudes above 5,700 m (18,700 ft). The Himalayan lakes also serve as breeding grounds for species such as black-necked crane and bar-headed goose . There are multiple species of reptiles including Japalura lizards, blind snakes , and insects such as butterflies . Several fresh water fish such as Glyptothorax are found in
18972-500: The region. As of 2022 , there are 575 protected areas established by the nations in the Himalayan-Hindu Kush region, which account for 40% of the land area and 8.5% of the global protected area. There are also four biodiversity hotspots , 12 ecoregions , 348 key biodiversity areas, and six UNESCO World Heritage Sites in the region. The Himalayan region with the associated Indo-Gangetic Plain and Tibetan plateau
19125-580: The same megalithic burials, pottery , iron technology, farming techniques and megalithic graffiti . This cultural complex spread from southern India along with Dravidian clans such as the Velir , prior to the migration of Prakrit speakers. The Annaicoddai seal , dated to the 3rd century BCE, contains a bilingual inscription in Tamil-Brahmi . Excavations in the area of Tissamaharama in southern Sri Lanka have unearthed locally issued coins produced between
19278-494: The same. The Himalayan region belongs to the Indomalayan realm . The flora and fauna of the Himalayas vary broadly across regions depending on the climate and geology. The Himalayas are home to multiple biodiversity hotspots, and is home to an estimated 35,000+ species of plants and 200+ species of animals. An average of 35 new species have been found every year since 1998. There are four types of vegetation found in
19431-593: The same. This has led to increased awareness on the impact of climate change, and adaptations such as change in crop cycles , introduction of drought resistant crops, and plantation of new trees. This has also led to the construction of more dams , canals , and other water structures, to prevent flooding and aid in agriculture. New plantations on barren lands to prevent landslides, and construction of fire lines made of litter and mud to prevent forest fires have been undertaken. However, lack of funding, awareness, access to technology, and government policy are barriers for
19584-509: The second century BCE and the second century CE, some of which carry Tamil personal names written in early Tamil letters, which suggest that Tamil merchants were present and actively involved in trade along the southern coast of Sri Lanka by the late classical period. Around 237 BCE, "two adventurers from southern India" took control of the Anuradhapura kingdom. In 145 BCE Elara, a Chola general or prince known as Ellāḷaṉ took over
19737-413: The slopes and the plains below. The effect of Himalayas on the hydroclimate impacts millions in the plains as the variability in monsoon rainfall is the main factor behind wet and dry years. As the Himalayas force the monsoon winds to give up most of the moisture before ascending up, the winds became dry once its reaches the north of the mountains. This results in the dry and windy cold desert climate in
19890-451: The slopes based on seasons. Various ethnic people such as Ladakhi , Balti , and Dard live on the north of the Great Himalayas along the Indus basin in the Kashmir and Ladakh regions spread across India, Pakistan, and China. The Dard speak Dard , which is part of Indo-European languages, while the Balti and Lakadkhi people speak Balti , and Ladakhi , which are part of Tibeto-Burman. In
20043-417: The snow-melt of the glaciers. The lower altitude lakes are replenished by a combination of rains, underground springs, and streams. Large lakes in the Himalayan basin were formed in the holocene period, when water pooled in the faults and the water supply was subsequently cut off. There are more than 4500 high altitude lakes of which about 12 large lakes contribute to more than 75% of the total lake area in
20196-409: The source of various rivers of the Ganges - Brahmaputra river system. The high altitude regions are uninhabitable with few mountain passes inbetween that serve as crossovers with the human settlements in the lower valleys. The Assam Himalaya forms the eastern most sub-section that extends eastward for 720 km (450 mi) from the Indian state of Sikkim through Bhutan and north-east India past
20349-470: The standard characters, six characters taken from the Grantha script , which was used in the Tamil region to write Sanskrit, are sometimes used to represent sounds not native to Tamil, that is, words adopted from Sanskrit, Prakrit , and other languages. The traditional system prescribed by classical grammars for writing loan-words, which involves respelling them in accordance with Tamil phonology, remains, but
20502-470: The summits of several peaks in the region such as Gangkhar Puensum , Machapuchare , and Kailash have been off-limits to climbers. The name of the range is derived from the Sanskrit word Himālay ( हिमालय ) meaning 'abode of snow'. It is a combination of the words him ( हिम ) meaning 'frost/cold' and ālay ( आलय ) meaning 'dwelling/house'. The name of the range is mentioned as Himavat ( Sanskrit : हिमवत्) in older literature such as
20655-584: The super-continent Gondwana broke up nearly 180 mya, the Indo-Australian plate slowly drifted northwards towards Eurasia for 130-140 million years. The Indian Plate broke up with the Australian Plate about 100 mya. The Tethys ocean constricted as the Indian plate moved gradually upward. As both the plates were made of continental crusts , which were less denser than oceanic crusts , the increased compressive forces resulted in folding of
20808-476: The term "Tamilakam" was divided among multiple kingdoms, its occurrence in the ancient literature implies that the region's inhabitants shared a cultural or ethnic identity, or at least regarded themselves as distinct from their neighbours. The ancient Tamil inscriptions, ranging from 5th century BCE to 3rd century CE, are also considered as linguistic evidence for distinguishing Tamilakam from the rest of South India. The ancient non-Tamil inscriptions, such as those of
20961-595: The throne at Anuradhapura and ruled for forty-four years. Dutugamunu , a Sinhalese , started a war against him, defeated him, and took over the throne. Tamil Kings have been dated in Sri Lanka to at least the 3rd century BCE. Hinduism ( Vaishnavism , Kaumaram , Shaktism , Shaivism ,), Dravidian folk religion , Jains and Buddhists have coexisted in Tamil country since at least the second century BCE. Tamil language Sri Lanka Singapore Malaysia Canada and United States Tamil ( தமிழ் , Tamiḻ , pronounced [t̪amiɻ] )
21114-612: The trees. The Eastern Himalayan alpine shrub and meadows extend between 3,200–4,200 m (10,500–13,800 ft) and the Western Himalayan alpine shrub and meadows occur at altitudes of 3,600–4,500 m (11,800–14,800 ft). Major vegetation include Juniperus , Rhododendron on rocky terrain facing the Sun, various flowering plants at high elevations, and mosses , and lichens in humid, shaded areas. Interspersed Grasslands occur at certain regions, with thorns and semi-desert vegetation at low precipitation areas in
21267-592: The tropical zone to extend farther north in South Asia than anywhere else in the world. The temperatures are more pronounced in the Brahmaputra valley in the eastern section as it lies at a lower latitude and due to the latent heat of the forced air from the Bay of Bengal which condenses before moving past the Namcha Barwa , the eastern anchor of the Himalayas. Due to this, the permanent snow line
21420-543: The trough between the Himalayas and the Deccan plateau formed the Indo-Gangetic Plain . About 0.6 mya in the pleistocene period, the Himalayas rose higher and became the highest mountains on Earth. In the northern Great Himalayas , new gneiss and granite formations emerged on crystalline rocks that gave rise to the higher peaks. The summit of Mount Everest is made of unmetamorphosed marine ordovician limestone with fossil trilobites , crinoids , and ostracods from
21573-540: The underlying rock bed. The thrust faults created between the folds resulted in granite and basalt rocks from the Earth's mantle protruding through the crust . During the paleogene period (about 50 mya), the Indian plate collided with the Eurasian plate after it completely closed the Tethys ocean gap.
