What causes higher rainfall on the western slope and lower rainfall on the eastern slope of the Western Ghats?
Answer and explanation
Correct answer: Orographic rainfall and rain-shadow effect
The correct answer is A. During the southwest monsoon, moisture-laden winds from the Arabian Sea encounter the Western Ghats. The mountains force the air to rise; as it rises, it cools, condenses, and produces heavy orographic rainfall on the western, windward slope. After crossing the crest, the air has lost much of its moisture and descends toward the Deccan Plateau, creating a comparatively dry leeward region called the rain-shadow area. Glacial melt, snowfall, coral deposition, sea waves, sandstorms, and desertification do not explain this west-east rainfall contrast. The governing concept is therefore relief rainfall followed by a rain-shadow effect.
