Which of the following statements is/are correct? 1. Himalayan rivers have their origin in the snow-covered areas, hence are dry in winter season. 2. Rivers of the Peninsular Plateau have reached maturity. 3. Himalayan rivers depict all the three stages of normal cycle of erosion. Select the correct answer using the code given below.
- A.2 only
- B.1 and 3 only
- C.2 and 3 only
- D.1, 2 and 3
Correct answer
Explanation
The correct answer is C, 2 and 3 only. Himalayan rivers are perennial, so statement 1 is wrong, while statements 2 and 3 are correct.
Himalayan rivers such as the Ganga, Indus and Brahmaputra rise from glaciers and snowfields and also get monsoon rain, so they flow all year round, including in winter. They are young rivers still cutting deep gorges in the mountains, then flowing through a mature stage in the plains and reaching an old stage with meanders and deltas near the sea, so they show all three stages of the erosion cycle. Peninsular rivers flow over an ancient, stable plateau and have broad, shallow valleys with graded courses, which marks them as mature rivers.
Option A is wrong because it leaves out statement 3, which is correct. Option B is wrong because statement 1 is false and statement 2 is left out. Option D is wrong because it includes the false statement 1.
Exam tip: Himalayan rivers are perennial and young; Peninsular rivers are seasonal and mature.
