Question

Difference between old mountains and young mountains

Answer 1

Explanation:

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

Answer:

• In general, we divide mountains into two groups based on their age. Young mountains with steep slopes and high-pointed peaks were formed some dozen million years ago.
• Old mountains, on the other hand, have rounded tops and gentler slopes due to millions of years of erosion.

Explanation:

Young mountains

• They are of recent origin.
• They are higher than the old fold mountains.
• Most of the young fold mountains have pointed peaks.
• These have steeper slopes and deeper valleys.
• The Himalayas, the Andes and the Rockies mountains are some examples of young fold mountains.

Old  mountains

• They have been formed long ago.
• They are lower than the young fold mountains.
• These mountains generally do not have pointed peaks due to erosional activities of exogenic forces. They have rounded peaks.
• Due to the erosional activities of the exogenic forces, these mountains have gentle slopes.
• The Aravali Range, the Appalachian and the Ural Mountains are some examples of old fold mountains.
