What is the Himalaya’s contribution to the perennial nature of Himalayan rivers?
Answer and explanation
Correct answer: Rivers get water from snow and rainfall
The governing concept is the difference between perennial and seasonal rivers. Himalayan rivers receive water from more than one continuing source: monsoon rainfall feeds them during the rainy season, while snow and glacier melt continue to supply water during warmer months. This combined supply helps rivers such as the Ganga, Yamuna, and Brahmaputra flow through much of the year, though their discharge still rises and falls seasonally. Thus option D is correct. Option A is meaningless because blocking water would not create a river supply; option B describes neither the main source nor the process; and option C concerns coral formation, which has no connection with Himalayan river flow.
