The Himalayas, or Himalaya (/ˌhɪməˈleɪə,hɪˈmɑːləjə/ ; Sanskrit: IPA: [ɦɪmɐːləjɐː], himá "snow", ā-laya "dwelling", "abode"[1]), are a mountain range in Asia separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the planet's highest peaks, including the highest, Mount Everest. Over 100 peaks exceeding 7,200 m (23,600 ft) in elevation lie in the Himalayas. By contrast, the highest peak outside Asia (Aconcagua, in the Andes) is 6,961 m (22,838 ft) tall.[2]
The Himalayas abut or cross five countries: Bhutan, India, Nepal, China, and Pakistan. The sovereignty of the range in the Kashmir region is disputed among India, Pakistan, and China.[3] The Himalayan range is bordered on the northwest by the Karakoram and Hindu Kush ranges, on the north by the Tibetan Plateau, and on the south by the Indo-Gangetic Plain. Some of the world's major rivers, the Indus, the Ganges, and the Tsangpo–Brahmaputra, rise in the vicinity of the Himalayas, and their combined drainage basin is home to some 600 million people; 53 million people live in the Himalayas.[4] The Himalayas have profoundly shaped the cultures of South Asia and Tibet. Many Himalayan peaks are sacred in Hinduism and Buddhism; the summits of several—Kangchenjunga (from the Indian side), Gangkhar Puensum, Machapuchare, Nanda Devi and Kailas in the Tibetan Transhimalaya—are off-limits to climbers.
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.[5] Its western anchor, Nanga Parbat, lies just south of the northernmost bend of the Indus river. Its eastern anchor, Namcha Barwa, lies immediately west of the great bend of the Yarlung Tsangpo River. The range varies in width from 350 km (220 mi) in the west to 150 km (93 mi) in the east.[6]
The name of the range hails from the Sanskrit Himālaya (हिमालय 'abode of the snow'), from himá (हिम 'snow') and ā-laya (आलय 'receptacle, dwelling').[7] They are now known as "the Himalaya Mountains", usually shortened to "the Himalayas". Following the etymology some writers refer to it as the Himalaya. This was also previously transcribed as Himmaleh, as in Emily Dickinson's poetry[8] and Henry David Thoreau's essays.[9]
The mountains are known as the Himālaya in Nepali and Hindi (both written हिमालय), Himāl (हिमाल) in Kumaoni, the Himalaya (ཧི་མ་ལ་ཡ་) or 'The Land of Snow' (གངས་ཅན་ལྗོངས་) in Tibetan, also known as Himālaya in Sinhala written as හිමාලය, the Himāliya Mountain Range (سلسلہ کوہ ہمالیہ) in Urdu, the Himaloy Parvatmala (হিমালয় পর্বতমালা) in Bengali and the Ximalaya Mountain Range (simplified Chinese: 喜马拉雅山脉; traditional Chinese: 喜馬拉雅山脉; pinyin: Xǐmǎlāyǎ Shānmài) in Chinese.
The Himalayas consist of parallel mountain ranges: the Sivalik Hills on the south; the Lower Himalayan Range; the Great Himalayas, which is the highest and central range; and the Tibetan Himalayas on the north.[11] The Karakoram are generally considered separate from the Himalayas.
