What is the main reason for considering the Western Ghats a rainfall barrier?
Answer and explanation
Correct answer: They lift moist winds of the Arabian Sea branch
Option B is correct because the Western Ghats form a high, fairly continuous barrier close to India’s western coast. Moisture-laden southwest monsoon winds from the Arabian Sea are forced to rise when they encounter this elevated relief. As the air rises, it cools, condensation occurs, and heavy orographic rainfall develops on the windward western slopes. After crossing the range, the air is comparatively drier, producing a rain-shadow effect over parts of the Deccan interior. The Western Ghats are not a branch of the Himalayas, they are not located wholly in a desert, and they are certainly not under the sea. Thus B explains the rainfall barrier effect.
