Question

Assertion (A) – The rivers flowing from mountains to plains tend to loose their speed. Reason (R) - The slopes become gentler over plains.​

Answer 1

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

Answer 2

The correct answer is Both A and R are correct and R is the correct explanation of A

Assertion (A) – The rivers flowing from mountains to plains tend to loose their speed.

All the rivers that originate from mountainous region flow with great speed initially.

However, as they enter the plains, they start losing their speed and flow very calmly.

Thus, assertion is correct.

Reason (R) - The slopes become gentler over plains.

In mountainous regions, the slope is very steep. Hence, the rivers flow at great velocity.

But, in the plains, the slope is not so high. Therefore, the rivers lose their speed.

Thus reason statement correctly explains the assertion statement.
