Consider the following statements: 1. River Kaveri has well developed valley 2. Valley of River Alakananda is still growing 3. River Krishna is largest east flowing peninsular river Which of the statements given above is/are correct?
- A.1 only
- B.1 and 2
- C.2 and 3
- D.2 only
Correct answer
Explanation
The correct answer is B, 1 and 2. The Kaveri is an old peninsular river with a mature valley, and the Alaknanda is a young Himalayan river still cutting its valley, but the largest east-flowing peninsular river is the Godavari, not the Krishna.
Peninsular rivers flow over one of the oldest landmasses on Earth. They have long reached a graded profile, flow in broad, shallow, well-developed valleys and do little downward cutting. Himalayan rivers such as the Alaknanda rise in young fold mountains that are still being uplifted, so they keep eroding downwards and form deep V-shaped valleys and gorges. The Godavari, about 1,465 km long with the biggest basin among peninsular rivers, is called the Dakshin Ganga; the Krishna is second.
A is wrong because it leaves out statement 2. C is wrong because statement 3 is false. D is wrong because statement 1 is also correct.
Exam tip: largest peninsular river Godavari, then Krishna; largest west-flowing peninsular river Narmada.
