Why can the Western Ghats be called a rainfall barrier?
Answer and explanation
Correct answer: They force moist south-west monsoon winds upward
The correct answer is B. The Western Ghats stand close to the Arabian Sea and intercept moisture-laden south-west monsoon winds. As these winds are forced to rise along the mountain slopes, they cool, condense, and produce orographic or relief rainfall on the windward side. After crossing the crest, the air descends and becomes relatively drier, contributing to a rain-shadow effect in parts of the Deccan Plateau. Option A refers to the wrong wind system, while C and D do not explain the rainfall mechanism. The Ghats act as a barrier because of their height, orientation, and position across the path of moist monsoon winds.
