Question

Why don't the rivers falling into the Arabian Sea form deltas?

• A. The sea-coast is hard and rocky soil
• B. These rivers have a short swift course and flow down steep slopes
• C. They do not have enough of water
• D. None of these

Answer 1

The correct option is B These rivers have a short swift course and flow down steep slopes

A large number of west flowing rivers in peninsular India flow into the Arabian Sea. The slope of the Western Ghats is steep and hence these rivers have a rapid flow. Due to this, the rivers carry their silt into deep sea.

At the same time, the Narmada and Tapti rivers flow via the rift valleys and while doing so the eroded material carried by them gets deposited in the fractures of the fault zones. Thus, they don’t form deltas.

Hence option B is the correct answer.
