Consider the following statements:

1. Assertion (A): West flowing rivers of Peninsular India have no deltas.
2. Reason (R): These rivers do not carry any alluvial sediments.

Options:

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

Explanation

Option (a) is correct

• The Narmada, Tapti, and most other west-flowing rivers of Peninsular India generally do not form deltas. Instead, they enter the sea through estuaries or narrow river mouths. This is mainly because the western part of Peninsular India is characterized by hard, rocky terrain with limited loose sediment available for deposition. Moreover, these rivers have relatively short courses and carry smaller quantities of alluvial material compared to the major east-flowing rivers. As a result, sufficient sediment does not accumulate at their mouths to form extensive deltas.

Answer: (a) Both A and R are individually true and R is the correct explanation of A
