Q. Consider the following statements regarding Himalayan and Peninsular rivers:

1. Most of the Himalayan rivers are perennial, while most Peninsular rivers are rainfed.
2. The gradient of Himalayan rivers is steeper than that of Peninsular rivers.
3. The Peninsular rivers cause more erosion on their course as compared to the Himalayan rivers.

Which of the above statements is / are correct?
Answer: Only 1 and 2
Notes: Statements 1 and 2 are correct as Himalayan rivers are mainly perennial and glacier-fed, while Peninsular rivers are primarily rainfed. The gradient, or slope, of the Himalayan rivers is naturally steeper, leading to faster flows. However, Himalayan rivers, not Peninsular rivers, cause more erosion due to their greater discharge and steeper gradients. Thus, statement 3 is incorrect.
