Question

There is heavy rainfall on the western coast of India but very little in the Deccan because _______.

• A. the Deccan plateau is situated in the rain shadow region of the Western Ghats
• B. the region is bypassed by the south-west monsoons
• C. lack of high mountains in the Deccan
• D. of some unknown reason

Answer 1

The correct option is A the Deccan plateau is situated in the rain shadow region of the Western Ghats

The Deccan plateau is situated in the rain shadow region of the Western Ghats. There is heavy rainfall on the western coast of India but very little in the Deccan because the Deccan plateau is situated in the rain shadow of the Western Ghats. The Deccan Plateau to the east of the Western Ghats receives significantly less rainfall than the coasts. 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.
