Answer to Question #28531 in Other Geography for dinesh chandra
why are Himalayas called young fold mountains ?
The Himalayan mountains began forming about 70 million years ago and continue to increase in elevation even today. That makes them among the youngest of mountain chains on the Earth, compared to older mountain ranges like the Aravallis in India, and the Appalachian in the USA. They are fold mountains because they’re formed by folding of the rocks along the edges of both continents from the force, pressure, and heat of the collision of the two continental plates involved, the Asian and the Indoaustralian.
