The Himalayas, or Himalaya (/ˌhɪməˈleɪə, hɪˈmɑːləjə/), (Sanskrit: himá (हिम, "snow") and ā-laya (आलय, "abode, receptacle, dwelling")), is a mountain range in Asia separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has many of Earth's highest peaks, including the highest, Mount Everest, at the border between Nepal and China. 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.[1]

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.[2] Its western anchor, Nanga Parbat, lies just south of the northernmost bend of the 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.[3] Towards the south, the arc of the Himalaya is ringed by the very low Indo-Gangetic Plain.[4] The range varies in width from 350 km (220 mi) in the west (Pakistan) to 150 km (93 mi) in the east (Arunachal Pradesh).[5]
The Himalayas are inhabited by 52.7 million people,[5] and are spread across five countries: Bhutan, China, India, Nepal and Pakistan. The Hindu Kush range in Afghanistan[6] and Hkakabo Razi in Myanmar are normally not included, but they are both (with the addition of Bangladesh) part of the greater Hindu Kush Himalayan (HKH) river system.[7][full citation needed]
