Answer 1

1. Western Ghats, Western Coasts of India and the northeastern region comprising Mawsynram, Cherrapunji and parts of Assam and Arunachal Pradesh get more than 4000 mm of rainfall.

These regions lie on the leeward side of the Western Ghats and Eastern Ghats. It rains less here and a rain shadow region is formed.
   2. Some parts of Gujarat and Rajasthan are also semi-arid, as the Aravallis lie parallel and do not obstruct the South-west Monsoon winds.
