Question

Why is the western part of India a desert region

Answer 1

So, basically these move in east towest direction. The winds shed their moisture in to eastern parts of the continent and become dry by the time they reach the western margins and so they bring no rainfall. Thus, the regionbecomes devoid of moisture which causes dry conditions leading to formation of deserts.

Answer 2

Answer:

The western part of Rajasthan is a desert region because :

• The south-west monsoon winds blow parallel to the Aravalli and are thus not obstructed by them and therefore, the rainfall is low in Rajasthan.

• Secondly, the Aravallis are low residual hills and thus do no not obstruct the westerlies and therefore the rainfall is low.
