what is difference between young mountain and old mountain​

Answer 1

Answer:

Generally, we distinguish two types of mountains, according to their age. Young mountains, created several dozen million years ago, have steep slopes and high-pointed peaks. ... Old mountains, in contrast, have rounded peaks and slopes made gentler by hundreds of millions of years of erosion.

Answer 2

There are two types of fold mountains: young fold mountains (10 to 25 million years of age, e.g. Rockies and Himalayas) and old fold mountains (over 200 million years of age, e.g. Urals and Appalachians of the USA).

The Himalayas, the Andes and the Rockies mountains are some examples of young fold mountains. The Aravali Range, the Appalachian and the Ural Mountains are some examples of old fold mountains.
