Question

 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.

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:

In the lower course of the river, ideal conditions for depositional landforms exist due to the sluggish flow and the reduced load-transporting capacity of the river. As the river slows down and divides into distributaries, its ability to carry sediment decreases, leading to the deposition of materials and the formation of features like deltas and levees. Thus, the reason correctly explains why deposition occurs in the lower course.
