Higher rainfall on the western slope of the Western Ghats and relative dryness in interior Deccan are linked with what?
Answer and explanation
Correct answer: Orographic rainfall and rain shadow
The governing concept is relief rainfall, also called orographic rainfall, and the rain-shadow effect. Moisture-laden southwest monsoon winds from the Arabian Sea strike the Western Ghats and are forced to rise. Rising air cools, condenses and produces heavy rain on the western, windward slope. After crossing the crest, the air descends, becomes relatively warmer and drier, and gives the interior Deccan a rain-shadow condition. Therefore option A explains both observations. Glacial deposition and snowfall are not the normal controls here, while coral formation, lagoons, sandstorms and deltas describe unrelated environments. The contrast is caused by the mountain barrier and wind direction.
