Question
CBSEENGE11011760

“The distribution of rainfall in India is not uniform.” Give three important reasons in support of this statement.

 

Solution
After observing rainfall distribution map of India, the distinguished characteristics are that the rainfall is highly unevenly distributed :

1. The rainfall declines abruptly from Bengal coast to west and north-west in the northern plains.

2. The rainfall in the peninsular plateau decreases eastward.

Such uneven distribution is determined by the following factors :

1. Presence of geographic features such as the Western Ghats, the foothills of Himalayan mountain and the N.E. hills. They receive annual rainfall more than 185 cm and it represents only 10% of country's area.

2. The direction and distance covered by monsoon branches is another factor creating variation in the rainfall distribution in the northern plains and interior Deccan Plateau. On this basis, 30% of country's area receives less than 60 cm of annual rainfall and remaining 60% of the area receives between 60 cm to the 185 cm.
