Question 10

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.

  1. Both A and R are true and R is the correct explanation of A.
  2. Both A and R are true but R does not explain A.
  3. A is true but R is false.
  4. A is false but R is true.
Answer

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

Explanation — Meanders are the result of both erosion and deposition work of rivers. Meanders generally form under conditions of a gentle slope and sufficient water in rivers. The river flow is diverted by an obstruction allowing the river to do lateral erosion work.
