The Himalayas are a chain of mountains which take origin in the Pamir Knot. They are Young fold mountains.

The Himalayas act as a natural border between the South Asian countries and the Central or East Asian countries. They have been a barrier against foreign invaders for South-Asian countries like India, Nepal, etc.

The Himalayas are a source of several perennial rivers. These rivers originate from the glaciers in the ranges and bring in the fertile silt as they flow down. They are also fresh rivers because they take origin in glaciers of the Himalayas, where the ice simply melts or breaks down into rivers.
