A mountain range or hill range is a series of mountains or hills ranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets.
Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within 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 the Alpide Belt. The Pacific Ring of Fire includes the Andes of South America, extends through the North American Cordillera along the Pacific Coast, the Aleutian Range, on through Kamchatka, 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 includes Indonesia and Southeast Asia, through the Himalaya, Caucasus Mountains, Balkan Mountains fold mountain range, the Alps, and ends in the Spanish mountains and the Atlas Mountains. The belt also includes other European and Asian mountain ranges. The Himalayas contain the highest mountains in the world, including Mount Everest, which is 8,848 metres (29,029 ft) high and traverses the border between China and Nepal.
Mountain ranges outside these two systems include the Arctic Cordillera, the Urals, the Appalachians, the Scandinavian Mountains, the Great Dividing Range, the Altai Mountains and the Hijaz Mountains. If the definition of a mountain range is stretched to include underwater mountains, then the Ocean Ridges form the longest continuous mountain system on Earth, with a length of 65,000 kilometres (40,400 mi).
The mountain systems of the earth are characterized by a tree structure, where mountain ranges can contain sub-ranges. The sub-range relationship is often expressed as a parent-child relationship. For example, the White Mountains of New Hampshire and the Blue Ridge Mountains are sub-ranges of the Appalachian Mountains. Equivalently, the Appalachians are the parent of the White Mountains and Blue Ridge Mountains, and the White Mountains and the Blue Ridge Mountains are children of the Appalachians.
The parent-child expression extends to the sub-ranges themselves: the Sandwich Range and the Presidential Range are children of the White Mountains, while the Presidential Range is parent to the Northern Presidential Range and Southern Presidential Range.
The position of mountains 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 the air descends on the leeward side, it warms again (in accordance with 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.
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 which are buried and turned into sedimentary rock. Erosion 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 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, 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 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 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 Boösaule Montes, Dorian Montes, Hi'iaka Montes and Euboea Montes.
The Alborz (listen Persian: البرز), also spelled as Alburz, Elburz or Elborz, is a mountain range in northern Iran that stretches from the border of Azerbaijan along the western and entire southern coast of the Caspian Sea and finally runs northeast and merges into the Aladagh Mountains in the northern parts of Khorasan. This mountain range is divided into Western, Central, and Eastern Alborz Mountains. The Western Alborz Range (usually called the Talysh) runs south-southeastward almost along the western coast of the Caspian Sea. The Central Alborz (the Alborz Mountains in the strictest sense) runs from west to east along the entire southern coast of the Caspian Sea, while the Eastern Alborz runs in a northeasterly direction towards the northern parts of the Khorasan region southeast of the Caspian Sea. Mount Damavand, the highest mountain in Iran measuring 5,610.0 m (18,405.5 ft), is located in the Central Alborz Mountains.Allegheny Mountains
The Allegheny Mountain Range , informally the Alleghenies and also spelled Alleghany and Allegany, is part of the vast Appalachian Mountain Range of the Eastern United States and Canada and posed a significant barrier to land travel in less technologically advanced eras. The barrier range has a northeast–southwest orientation and runs for about 400 miles (640 km) from north-central Pennsylvania, through western Maryland and eastern West Virginia, to southwestern Virginia.
The Alleghenies comprise the rugged western-central portion of the Appalachians. They rise to approximately 4,862 feet (1,483 m) in northeastern West Virginia. In the east, they are dominated by a high, steep escarpment known as the Allegheny Front. In the west, they slope down into the closely associated Allegheny Plateau, which extends into Ohio and Kentucky. The principal settlements of the Alleghenies are Altoona, State College, and Johnstown, Pennsylvania; and Cumberland, Maryland.Andes
The Andes or Andean Mountains (Spanish: Cordillera de los Andes) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The Andes also have the 2nd most elevated highest peak of any mountain range, only behind the Himalayas. The range is 7,000 km (4,300 mi) long, 200 to 700 km (120 to 430 mi) wide (widest between 18° south and 20° south latitude), and has an average height of about 4,000 m (13,000 ft). The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and Argentina.
Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus – some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Sucre, Mérida and La Paz. The Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes.
The Andes Mountains are the world's highest mountain range outside Asia. The highest mountain outside Asia, Argentina's Mount Aconcagua, rises to an elevation of about 6,961 m (22,838 ft) above sea level. The peak of Chimborazo in the Ecuadorian Andes is farther from the Earth's center than any other location on the Earth's surface, due to the equatorial bulge resulting from the Earth's rotation. The world's highest volcanoes are in the Andes, including Ojos del Salado on the Chile-Argentina border, which rises to 6,893 m (22,615 ft).
The Andes are also part of the American Cordillera, a chain of mountain ranges (cordillera) that consists of an almost continuous sequence of mountain ranges that form the western "backbone" of North America, Central America, South America and Antarctica.Anti-Lebanon Mountains
The Anti-Lebanon Mountains (Arabic: جبال لبنان الشرقية, Jibāl Lubnān ash-Sharqiyyah, lit. "Eastern Mountains of Lebanon"; Lebanese Arabic: جبال الشرقية, Jbel esh-Shar'iyyeh, "Eastern Mountains") are a southwest-northeast-trending mountain range that forms most of the border between Syria and Lebanon. The border is largely defined along the crest of the range. Most of the range lies in Syria.
Its Western name Anti-Lebanon comes from the Greek and Latin Antilibanus, derived from its position opposite and parallel to the Mount Lebanon range. It ends in the south with Mount Hermon, which borders on the Golan Heights; the Golan Heights are a different geological and geomorphological entity, but geopolitically they are often regarded together with the southern slopes of Mount Hermon, both being part of the Israeli-controlled Golan region. To the west of the Anti-Lebanon lie valleys that separate it from Mount Lebanon in central Lebanon: Beqaa Valley in the north and the Hasbani River valley in the south. To the east, in Syria, lies the Eastern Plateau, location of the city of Damascus.
The Anti-Lebanon range is approximately 150 kilometres (93 miles) in length. To the north, it extends to almost the latitude of the Syrian city of Homs. To the south, the range adjoins the lower-laying Golan Heights plateau, but includes the highest peaks, namely Mount Hermon (Jabal el-Shaykh, in Arabic), at 2,814 metres, and Ta'la't Musa, at 2,669 metres. These peaks, on the Lebanese-Syrian border, are snow-covered for much of the year.
An important smuggling route between Lebanon and Syria passes through the Anti-Lebanon MountainsThe area is known for its apricot and cherry trees as well as its stone quarries.There are various endemic flora found and named after the region, (having a Latin specific epithet) including Euphorbia antilibanotica,Teucrium antilibanoticum, Valerianella antilibanotica, and Iris antilibanotica.Appalachian Mountains
The Appalachian Mountains, often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east–west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west.
Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the Appalachian Highlands physiographic division as consisting of thirteen provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, Saint Lawrence Valley, Appalachian Plateaus, New England province, and the Adirondack areas. A common variant definition does not include the Adirondack Mountains, which geologically belong to the Grenville Orogeny and have a different geological history from the rest of the Appalachians.Baldwin Hills (mountain range)
The Baldwin Hills are a low mountain range surrounded by and rising above the Los Angeles Basin plain in central Los Angeles County, California. The Pacific Ocean is to the west, the Santa Monica Mountains to the north, Downtown Los Angeles to the northeast, and the Palos Verdes Hills to the south - with all easily viewed from the Baldwin Hills.Carpathian Mountains
The Carpathian Mountains or Carpathians () are a range of mountains forming an arc throughout Central and Eastern Europe. Roughly 1,500 km (932 mi) long, it is the third-longest European mountain range after the Urals with 2,500 km (1,553 mi) and the Scandinavian Mountains with 1,700 km (1,056 mi). The range stretches from the far eastern Czech Republic (3%) in the northwest through Slovakia (17%), Poland (10%), Hungary (4%) and Ukraine (10%) Serbia (5%) and Romania (50%) in the southeast. The highest range within the Carpathians is known as the Tatra mountains in Slovakia, where the highest peaks exceed 2,600 m (8,530 ft). The second-highest range is the Southern Carpathians in Romania, where the highest peaks range between 2,500 m (8,202 ft) and 2,550 m (8,366 ft).
The divisions of the Carpathians are usually in three major sections:
Western Carpathians—Austria, Czech Republic, Poland, Slovakia and Hungary
Eastern Carpathians—southeastern Poland, eastern Slovakia, Ukraine, and Romania
Southern Carpathians—Romania and SerbiaThe term Outer Carpathians is frequently used to describe the northern rim of the Western and Eastern Carpathians.
The Carpathians provide habitat for the largest European populations of brown bears, wolves, chamois, and lynxes, with the highest concentration in Romania, as well as over one third of all European plant species. The mountains and their foothills also have many thermal and mineral waters, with Romania having one-third of the European total. Romania is likewise home to the second-largest surface of virgin forests in Europe after Russia, totaling 250,000 hectares (65%), most of them in the Carpathians, with the Southern Carpathians constituting Europe's largest unfragmented forest area. Deforestation rates due to illegal logging in the Carpathians are high.The most important cities in or near the Carpathians are: Bratislava and Košice in Slovakia, Kraków in Poland, Cluj-Napoca, Sibiu, and Braşov in Romania, and Uzhhorod in Ukraine.Cascade Range
The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as the North Cascades, and the notable volcanoes known as the High Cascades. The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as the Cascade Mountains. The latter term is also sometimes used by Washington residents to refer to the Washington section of the Cascades in addition to North Cascades, the more usual U.S. term, as in North Cascades National Park. The highest peak in the range is Mount Rainier in Washington at 14,411 feet (4,392 m).
The Cascades are part of the Pacific Ocean's Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. All of the eruptions in the contiguous United States over the last 200 years have been from Cascade volcanoes. The two most recent were Lassen Peak from 1914 to 1921 and a major eruption of Mount St. Helens in 1980. Minor eruptions of Mount St. Helens have also occurred since, most recently from 2004 to 2008. The Cascade Range is a part of the American Cordillera, a nearly continuous chain of mountain ranges (cordillera) that form the western "backbone" of North America, Central America, and South America.Caucasus Mountains
The Caucasus Mountains are a mountain system at the intersection of Europe and Asia. Stretching between the Black Sea and the Caspian Sea, it surrounds the eponymous Caucasus region and is home to Mount Elbrus, the highest peak in Europe.
The Caucasus Mountains include the Greater Caucasus in the north and Lesser Caucasus in the south. The Greater Caucasus runs west-northwest to east-southeast, from the Caucasian Natural Reserve in the vicinity of Sochi on the northeastern shore of the Black Sea nearly to Baku on the Caspian Sea. The Lesser Caucasus runs parallel to the Greater about 100 km (62 mi) south. The Greater and Lesser Caucasus ranges are connected by the Likhi Range, and to the west and east of the Likhi Range lie the Colchis Plain and the Kur-Araz Lowland. The Meskheti Range is a part of the Lesser Caucasus system. In the southeast the Aras River separates the Lesser Caucasus from the Talysh Mountains which straddle the border of southeastern Azerbaijan and Iran. The Lesser Caucasus and the Armenian Highland constitute the Transcaucasian Highland, which at their western end converge with the highland plateau of Eastern Anatolia in the far north east of Turkey. The highest peak in the Caucasus range is Mount Elbrus in the Greater Caucasus, which rises to a height of 5,642 metres (18,510 ft) above sea level. Mountains near Sochi hosted part of the 2014 Winter Olympics.Central Mountain Range
The Central Mountain Range is the principal mountain range on Taiwan Island. It runs from the north of the island to the south. Due to this separation, connecting between the west and east is not very convenient. The tallest peak of the range is Xiuguluan Mountain, 3,860 m (12,664 ft).Haraz River
The Haraz River (Persian: هراز) is a notable river flowing through the Mazandaran Province of northern Iran. It flows northwards, from the Alborz mountain range into the Caspian Sea.Himalayas
The Himalayas, or Himalaya (), form a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has many of the Earth's highest peaks, including the highest, Mount Everest. The Himalayas include over fifty mountains exceeding 7,200 m (23,600 ft) in elevation, including ten of the fourteen 8,000-metre peaks. By contrast, the highest peak outside Asia (Aconcagua, in the Andes) is 6,961 m (22,838 ft) tall.Lifted by the subduction of the Indian tectonic plate under the Eurasian Plate, the Himalayan mountain range runs west-northwest to east-southeast in an arc 2,400 km (1,500 mi) long. Its western anchor, Nanga Parbat, lies just south of the northernmost bend of Indus river. Its eastern anchor, Namcha Barwa, is just west of the great bend of the Yarlung Tsangpo River (upper stream of the Brahmaputra River). The Himalayan range is bordered on the northwest by the Karakoram and the Hindu Kush ranges. To the north, the chain is separated from the Tibetan Plateau by a 50–60 km (31–37 mi) wide tectonic valley called the Indus-Tsangpo Suture. Towards the south the arc of the Himalaya is ringed by the very low Indo-Gangetic Plain. The range varies in width from 350 km (220 mi) in the west (Pakistan) to 150 km (93 mi) in the east (Arunachal Pradesh). The Himalayas are distinct from the other great ranges of central Asia, although sometimes the term 'Himalaya' (or 'Greater Himalaya') is loosely used to include the Karakoram and some of the other ranges.
The Himalayas are inhabited by 52.7 million people, and are spread across five countries: Nepal, India, Bhutan, China and Pakistan. Some of the world's major rivers – the Indus, the Ganges and the Tsangpo-Brahmaputra – rise in the Himalayas, and their combined drainage basin is home to roughly 600 million people. The Himalayas have a profound effect on the climate of the region, helping to keep the monsoon rains on the Indian plain and limiting rainfall on the Tibetan plateau. The Himalayas have profoundly shaped the cultures of the Indian subcontinent, with many Himalayan peaks considered sacred in Hinduism and Buddhism.Karakoram
The Karakoram is a large mountain range spanning the borders of Pakistan, India, and China, with the northwest extremity of the range extending to Afghanistan and Tajikistan. It begins in the Wakhan Corridor (Afghanistan) in the west and encompasses the majority of Gilgit–Baltistan (Pakistan) and extends into Ladakh (India), and the disputed Aksai Chin region controlled by China. It is the second highest mountain range in the world, and part of the complex of ranges including the Pamir Mountains, the Hindu Kush and the Himalayan Mountains.. The Karakoram has eight summits over 7,500 m (24,600 ft) height, with four of them exceeding 8,000 m (26,000 ft): K2, the second highest peak in the world at 8,611 m (28,251 ft), Gasherbrum I, Broad Peak and Gasherbrum II.
The range is about 500 km (311 mi) in length, and is the most heavily glaciated part of the world outside the polar regions. The Siachen Glacier at 76 kilometres (47 mi) and the Biafo Glacier at 63 kilometres (39 mi) rank as the world's second and third longest glaciers outside the polar regions.The Karakoram is bounded on the east by the Aksai Chin plateau, on the northeast by the edge of the Tibetan Plateau, and on the north by the river valleys of the Yarkand and Karakash rivers beyond which lie the Kunlun Mountains. At the northwest corner are the Pamir Mountains. The southern boundary of the Karakoram is formed, west to east, by the Gilgit, Indus, and Shyok rivers, which separate the range from the northwestern end of the Himalaya range proper. These rivers flow northwest before making an abrupt turn southwestward towards the plains of Pakistan. Roughly in the middle of the Karakoram range is the Karakoram Pass, which was part of a historic trade route between Ladakh and Yarkand but now inactive.
The Tashkurghan National Nature Reserve and the Pamir Wetlands National Nature Reserve in the Karalorun and Pamir mountains have been nominated for inclusion in UNESCO in 2010 by the National Commission of the People's Republic of China for UNESCO and has tentatively been added to the list.Kunlun Mountains
The Kunlun Mountains (simplified Chinese: 昆仑山; traditional Chinese: 崑崙山; pinyin: Kūnlún Shān, pronounced [kʰu̯ə́nlu̯ə̌n ʂán]; Mongolian: Хөндлөн Уулс, Khöndlön Uuls; Uyghur: كۇئېنلۇن تاغ تىزمىسى) are one of the longest mountain chains in Asia, extending more than 3,000 kilometres (1,900 mi). In the broadest sense, the chain forms the northern edge of the Tibetan Plateau south of the Tarim Basin.
The exact definition of this range varies. An old source uses Kunlun to mean the mountain belt that runs across the center of China, that is, Kunlun in the narrow sense: Altyn Tagh along with the Qilian and Qin Mountains. A recent source has the Kunlun range forming most of the south side of the Tarim Basin and then continuing east south of the Altyn Tagh. Sima Qian (Records of the Grand Historian, scroll 123) says that Emperor Wu of Han sent men to find the source of the Yellow River and gave the name Kunlun to the mountains at its source. The name seems to have originated as a semi-mythical location in the classical Chinese text Classic of Mountains and Seas.Teton Range
The Teton Range is a mountain range of the Rocky Mountains in North America. It extends for approximately 40 miles (64 km) in a north–south direction through the U.S. state of Wyoming, east of the Idaho state line. It is south of Yellowstone National Park and most of the east side of the range is within Grand Teton National Park.
Early French voyageurs named the range les trois tétons ("the three nipples") after the distinct breast-like shapes of its peaks, from which the modern name is derived. It is likely that the local Shoshone people once called the whole range Teewinot, meaning "many pinnacles".The principal summits of the central massif, sometimes referred to as the Cathedral Group, are Grand Teton (13,775 feet (4,199 m)), Mount Owen (12,928 feet (3,940 m)), Teewinot (12,325 feet (3,757 m)), Middle Teton (12,804 feet (3,903 m)) and South Teton (12,514 feet (3,814 m)). Other peaks in the range include Mount Moran (12,605 feet (3,842 m)), Mount Wister (11,490 feet (3,500 m)), Buck Mountain (11,938 feet (3,639 m)) and Static Peak (11,303 feet (3,445 m)).Ural Mountains
The Ural Mountains (; Russian: Ура́льские го́ры, tr. Uralskiye gory, IPA: [ʊˈralʲskʲɪjə ˈgorɨ]; Bashkir: Урал тауҙары, Ural tauźarı), or simply the Urals, are a mountain range that runs approximately from north to south through western Russia, from the coast of the Arctic Ocean to the Ural River and northwestern Kazakhstan.
The mountain range forms part of the conventional boundary between the continents of Europe and Asia. Vaygach Island and the islands of Novaya Zemlya form a further continuation of the chain to the north into the Arctic Ocean.
The mountains lie within the Ural geographical region and significantly overlap with the Ural Federal District and with the Ural economic region. They have rich resources, including metal ores, coal, and precious and semi-precious stones. Since the 18th century the mountains have contributed significantly to the mineral sector of the Russian economy.Vosges
The Vosges (, French: [voʒ] (listen); German: Vogesen [voˈɡeːzn̩] (listen); Alsatian: Vogese) are a range of low mountains in eastern France, near its border with Germany. Together with the Palatine Forest to the north on the German side of the border, they form a single geomorphological unit and low mountain range of around 8,000 km2 (3,100 sq mi) in area. It runs in a north-northeast direction from the Burgundian Gate (the Belfort–Ronchamp–Lure line) to the Börrstadt Basin (the Winnweiler–Börrstadt–Göllheim line), and forms the western boundary of the Upper Rhine Plain.
The Grand Ballon is the highest peak at 1,424 m (4,672 ft), followed by the Storkenkopf (1,366 m, 4,482 ft), and the Hohneck (1,364 m, 4,475 ft).Western Ghats
The Western Ghats, also known as Sahyadri (Benevolent Mountains), are a mountain range that covers an area of 140,000 square kilometres (54,000 sq mi) in a stretch of 1,600 kilometres (990 mi) parallel to the western coast of the Indian peninsula, traversing the states of Kerala, Tamil Nadu, Karnataka, Goa, Maharashtra and Gujarat. It is a UNESCO World Heritage Site and is one of the eight "hottest hot-spots" of biological diversity in the world. It is sometimes called the Great Escarpment of India. It contains a large proportion of the country's flora and fauna, many of which are only found in India and nowhere else in the world. According to UNESCO, the Western Ghats are older than the Himalayas. They influence Indian monsoon weather patterns by intercepting the rain-laden monsoon winds that sweep in from the south-west during late summer. The range runs north to south along the western edge of the Deccan Plateau, and separates the plateau from a narrow coastal plain, called Konkan, along the Arabian Sea. A total of thirty-nine areas in the Western Ghats, including national parks, wildlife sanctuaries and reserve forests, were designated as world heritage sites in 2012 – twenty in Kerala, ten in Karnataka, five in Tamil Nadu and four in Maharashtra.The range starts near the Songadh town of Gujarat, south of the Tapti river, and runs approximately 1,600 km (990 mi) through the states of Maharashtra, Goa, Karnataka, Kerala and Tamil Nadu ending at Marunthuvazh Malai, at Swamithope, near the southern tip of India. These hills cover 160,000 km2 (62,000 sq mi) and form the catchment area for complex riverine drainage systems that drain almost 40% of India. The Western Ghats block southwest monsoon winds from reaching the Deccan Plateau. The average elevation is around 1,200 m (3,900 ft).The area is one of the world's ten "hottest biodiversity hotspots" and has over 7,402 species of flowering plants, 1,814 species of non-flowering plants, 139 mammal species, 508 bird species, 179 amphibian species, 6,000 insects species and 290 freshwater fish species; it is likely that many undiscovered species live in the Western Ghats. At least 325 globally threatened species occur in the Western Ghats.Wet Mountains
The Wet Mountains are a small mountain range in southern Colorado, named for the amount of snow they receive in the winter. They are a sub-range of the Sangre de Cristo Mountains, in the southern Rocky Mountains System. There are three variant names of mountain range: Cuerno Verde, Greenhorn Mountains, and Sierra Mojada.
