The Western Ghats receive very heavy rainfall chiefly because
Answer: A
Correct answer: they force the moist southwest monsoon air to rise
The Western Ghats run parallel to the Arabian Sea coast and stand directly across the path of the southwest monsoon. Moist air arriving from the sea is forced to rise over them; rising air expands and cools, its water vapour condenses, and rain falls on the windward slopes. This is orographic rainfall. The windward side receives over 2,500 mm a year in places, while the Deccan plateau immediately behind lies in a rain shadow and may receive under 600 mm. The transition occurs within a short distance, and it is why the interior of Maharashtra and Karnataka is so much drier than the coast a hundred kilometres away. The descending air on the leeward side warms by compression, which raises its capacity to hold moisture and makes it drying rather than raining air. The Ghats are also a global biodiversity hotspot and the source of the Godavari, Krishna and Kaveri.
