How is the relation between rain shadow and cold desert in Ladakh Plateau understood?
Answer and explanation
Correct answer: Dryness increases due to altitude and mountain barriers
The governing concept is the rain-shadow effect combined with high-altitude conditions. Moisture-bearing monsoon winds lose much of their water while crossing or rising over major mountain barriers. Ladakh lies on the leeward side of the Himalayas and receives very little precipitation. Its great elevation also produces low temperatures, so the region is known as a cold desert. Therefore, option A is correct. Increased marine humidity would encourage rainfall rather than dryness, while coral reefs and the Ganga Delta are coastal or fluvial features unrelated to Ladakh’s high, enclosed plateau environment.
