Question 16

Assertion (A): In the lower course of the river all the ideal conditions for depositional landforms exist.

Reason (R): The load-transporting capacity is drastically reduced due to sluggish flow as well as division of a river into many distributaries.

  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 — The load-transporting capacity is drastically reduced due to sluggish flow as well as division of a river into many distributaries. This is why deposition becomes dominant in the lower course of the river.
