INDIAN GEOGRAPHY

Detailed explanation-1: -The western coast of India receives very high rainfall in summer mainly due to the Western Ghats. Due to the greater width of the mountains, the rain-bearing winds have to necessarily travel a longer distance and have more time for the drops to coalesce and precipitate as rainfall, resulting in higher rainfall.

Detailed explanation-2: -Eastern region of Western Ghats lie in the rain shadow region. Western Ghats are very tall that it blocks moisture-laden south-west winds to reach eastern slopes and hence receives scanty rainfall. Thus western slopes of Western Ghats receive more rainfall than eastern slopes.

Detailed explanation-3: -The correct option is D Orographic.

Detailed explanation-4: -The winds from Arabian Sea climb the slopes of the Western Ghats from 900-1200 m. Soon, they become cool, and as a result, the windward side of the Western Ghats receive very heavy rainfall ranging between 250 cm and 400 cm.

Detailed explanation-5: -As the summer (wet) monsoons approach the West Coast of India, they rise up the western Ghats (mountains) and the air cools. This cool air is less able to hold moisture and it is released as rainfall. This is called OROGRAPHIC RAINFALL.
