Compared with the Eastern Ghats, the continuity of the Western Ghats strengthens which effect?
Answer and explanation
Correct answer: Monsoon rainfall barrier effect on western coast
The governing concept is orographic rainfall caused by a mountain barrier. The Western Ghats run for a long, comparatively unbroken distance close to the Arabian Sea coast. Moist south-west monsoon winds are forced to rise when they meet this elevated wall. Rising air cools, condenses and produces heavy rainfall on the windward western slopes, while descending air on the eastern side is comparatively drier. Their greater continuity makes this barrier effect stronger than the generally discontinuous Eastern Ghats. Therefore option A is correct. Ganga delta formation depends on river deposition, Thar expansion depends on aridity and regional processes, and coral formation in Ladakh is geographically and environmentally impossible.
