Question

Assertion (A): The residual mountains are an outcome of the action of erosion.

Reason (R): The residual mountains are low in height.

Options

• Both A and R are true and R is the correct reason for A.

• Both A and R are true but R is not the correct reason for A.

• A is true and R is false.

• A is false and R is true.

Answer 1

A is true and R is false.

Explanation:

Residual mountains are formed due to the action of erosion which leaves behind resistant rock masses as mountains. However, these mountains are generally high in height, not low. Therefore, the assertion that residual mountains are an outcome of erosion is true, but the reason stating they are low in height is false.
