Question

Give a geographical reason for the following:

Residual mountains are also called mountains of denudation.

Answer 1

Residual mountains are called mountains of denudation because they are the remnants left after long periods of erosion and weathering. These mountains have been worn down by denudation processes (such as wind, water, and ice), which gradually lowered their original height. As a result, they have rounded tops and gentler slopes compared to their original form, making them a product of denudation. An example is the Nilgiri Hills.
