Question

The average rainfall in India is
A. 105cm
B. 90cm
C. 120cm
D. 100cm

Answer 1

Hint: Precipitations have a major impact on productivity and species richness of perennials or community. Climate changes affect biodiversity. As the climate change alters weather and temperature patterns, it will also impact animal and plant life.

Complete answer:
The average rainfall in India is 120 cm. The South-west monsoon constitutes 75% of the total rainfall from June to September, 13% of the rain by north-east monsoon from October to December, 10% of the rain by the pre monsoon cyclonic rainfall which is mainly in April and May and rest of the 2% by western disturbances from December to February.
The North-Eastern India and the western coast annually receive over about 400 cm of rainfall. But, it is less than 60 cm in the western Rajasthan, Haryana, adjoining parts of Gujarat and Punjab. Rainfall is equally less in the east of the Sahyadris and in the interior of the Deccan plateau. An area with low precipitation is around Leh in Jammu and Kashmir. The rest of the places in the country receive moderate rainfall. Snowfall is usually restricted to the Himalayan region. Owing to the nature of monsoons, annual rainfall is highly variable in each year. Variability is high in places with low rainfall such as parts of Gujarat, Rajasthan, and the leeward side of the Western Ghats. While areas receiving high rainfall are liable to be affected by the floods, the areas of low rainfall are drought-prone.

Hence, the correct answer is option (C).

Note: Mawsynram, a district of Meghalaya state in northeastern India, receives the highest rainfall. Jaisalmer receives the lowest rainfall in India.
