1. Sub Topic- Distribution of Rainfall & Monsoon as a Unifying Bond (pg 35)

 Distribution of Rainfall
 Rainfall distribution is not the same for every part of the country. While
northeastern India and theparts of the western coast receive about 400 cm of
rainfall annually, western Rajasthan and thewestern parts of Gujarat, Punjab and
Haryana receive less than 60 cm of rainfall.
 The winds which rise from the Arabian Sea are full of moisture. These winds
strike the mountains onthe western side resulting in heavy rainfall. By the time
these winds reach the Eastern Ghats, they arealready dry as they already shed
their moisture. Hence, the Western Ghats receive more rainfall thanthe Eastern
Ghats.
 Rainfall is also low in the Eastern Ghats, interior parts of the Deccan Plateau and
the Leh region ofJammu and Kashmir.
 The other parts of the country receive moderate rainfall.
 Such a distribution of rainfall causes great climatic variations. While the eastern
parts of the countryalmost get flooded every year, the western parts of the
country experience drought like situations.
 Monsoon as a Unifying Bond
Although the monsoon winds are irregular and uncertain, they unify the entire
country. The farmers eagerly wait for the arrival of rainfall. Rainfall provides the
water required to set agricultural activities in motion. Its arrival is welcomed with
the celebration of festivals, singing and dancing.
