what is the extent of himalayas from west to east
Himalayas 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 kilometres (1,500 mi) long.[2] 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 kilometres (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 kilometres (220 mi) in the west (Pakistan) to 150 kilometres (93 mi) in the east (Arunachal Pradesh).[5] 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.
Climatic regions of India The foothills of the Himalayas, Punjab-Haryana plain adjacent to the Himalayas, Rajasthan east of the Aravalli range, Uttar Pradesh, Bihar and northern part of West Bengal and Assam experience this climate. The rainfall is received mostly in the summer and is about 65 cm in the west and increases to 250 cm annually to the east and near the Himalayas. The winters are mainly dry due to the land derived winter winds which blow down the lowlands of north India towards the Bay of Bengal. The summers are hot and temperatures can reach 46 °C in the lowlands. May and June are the hottest months. Winter months are mostly dry with feeble winds. Frost occurs for a few weeks in winter. The difference in rainfall between the east and the west gives rise to a wide difference in the natural vegetation.
