Question

Assertion (A): River meanders are bends of longitudinal courses.

Reason (R): Meanders are the result of both erosion and deposition under conditions of a gentle slope and sufficient water in rivers.

Options

• Both A and R are true, and R is the correct explanation of A.

• Both A and Rare true, but R does not explain A.

• A is true, but R is false.

• A is false, but R is true.

Answer 1

Both A and R are true, and R is the correct explanation of A.

Explanation:

River meanders are bends in the longitudinal course of a river. They form due to erosion on the outer banks and deposition on the inner banks, which occurs under conditions of a gentle slope and sufficient water. This process explains why meanders develop in rivers with a low gradient and ample flow, making the reason a valid explanation for the assertion.
