Question

Assertion (A): Weathering is a precondition for the formation of soil and regolith.

Reason (R): The loose rock material on the bedrock is called regolith.

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

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

Explanation:

Weathering is indeed a precondition for the formation of soil and regolith because it breaks down rocks into smaller particles forming soil and regolith. The loose rock material lying on the bedrock is called regolith, confirming that R correctly explains A.
