What is the main physical reason for high rainfall in the Western Ghats?
Answer and explanation
Correct answer: They lift moist monsoon winds
The governing concept is orographic, or relief, rainfall. During the southwest monsoon, moisture-laden winds from the Arabian Sea move towards the west coast. The Western Ghats form a significant elevated barrier, forcing these winds to rise along their windward slopes. As the air rises, it cools, condensation occurs, and heavy rainfall develops on the western side. Therefore option D is correct. The Ganga Plain is far from the relevant barrier, Thar's sandy winds do not produce this mechanism, and the Ghats are not underwater. Rainfall is especially high where moist air meets steep relief, which explains the physical cause.
