Question

mountains of the world for example the Himalayas were largely a source of securing rainfall and rivers why

Answer 1

The Himalayan range has many of the Earth's highest peaks, including the highest, Mount Everest. The Himalayas include over fifty mountains exceeding 7,200 metres (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 metres (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 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.
