Give a geographical reason for each of the following:

(i) The northern plains of India do not freeze in winter.

(ii) In spite of Aravali Range, Rajasthan receives scanty rainfall.

(iii) Patna receives heavier rain than Delhi.

(i) The northern plains of India do not freeze in winter because the Himalayas form a climatic barrier separating the Indian subcontinent from the rest of Asia. They prevent the cold Siberian winds from entering India.

(ii) The state of Rajasthan receive scanty rainfall because it lies in the rain-shadow region of the Aravali Mountains. The Aravali Hills run parallel to the Arabian Sea branch, and thus do not form any barrier to intercept the winds. The winds thus passes through Rajasthan without causing any rainfall.

(iii) Patna receives heavier rain than Delhi because Patna is on the eastern side as compared to Delhi and places situated on the eastern side receive heavier rainfall than the places situated on the western side of the country.
