Question

why is the western part of Rajasthan arid in spite of the Aravalli Hills?



please help me in my homework.​

Answer 1

Answer:

The Aravallis system lies winds parallel to the direction of S.W. monsoon winds coming from Arabian Sea. ... So this mountain system is unable to check these winds and hence, western Rajasthan is practically dry.

Answer 2

Answer:

The western part of Rajasthan is desert. It gets an annual rainfall less than 20 cm. This is due to the following reasons :

(i) Rajasthan is under the influence of S.W. summer monsoons. The Aravallis system lies winds parallel to the direction of S.W. monsoon winds coming from Arabian Sea. So this mountain system is unable to check these winds and hence, western Rajasthan is practically dry. The southern parts get some rainfall.

(ii) This area lies at a great distance from the Bay of Bengal. The Bay of Bengal monsoon becomes dry and lose its moisture when it reaches Rajasthan.

(iii) This area is away from the Himalayan region. So it does not come under the influence of monsoon giving rain in the sub-Himalayan region.
