These winds enter the country and strike the mountains and the hills, causing
heavy rainfall. India receives three fourths of the total rainfall during this
season. Since these winds enter from the South West direction of the country
they are known as South - West Monsoon winds. The temperature decreases 2°C to
6°C on an average from that in the summer season. This season is also termed as
pre - monsoon or season of advancing monsoon.)

31. Explain
the Importance of Monsoon: (A large number of Indian people depend on
agriculture for their livelihood. Thus, monsoon rains act as a unifying factor
and yield good crops for them. India is an agricultural country. Its economy is
greatly influenced by monsoon that results in adequate amount of crop
production and facilitates its export. The monsoon season prevails in the
country for a short duration. This leads to scarcity of water at certain times.
Sudden heavy downpour may cause floods in the country. Again, little or no
rainfall may lead to droughts. Thus, management of monsoon water by
constructing dams, irrigation canals, etc. is important in our country.)
