The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Although major portion of India , gets rainfall through
summer monsoon during months of June-September, North western states and South
India also have a winter rainfall regime. Both are due to different reasons:
The phenomena which causes rainfall in north western states
pf Punjab,Haryana,Rajasthan, Western Uttar Pradesh is called western
disturbances. These are basically the sub-tropical cyclonic depressions from
Mediterranean Sea which are carried to Indian subcontinent through jet streams.
Their arrival results in onset of winter’s season in northern parts of country.
The moisture provided by western disturbances are vital for the cultivation of
rabi crops like wheat, gram etc.
Southern India: During winters, the monsoon winds get
reversed to North eastern winds. Most of them are dry due to coming from land
mass, but the bay of Bengal branch picks the moisture from sea and yields
rainfall particularly in the eastern state of Tamil Nadu in southern India. As
eastern coasts do not receive much of rainfall in south west monsoon, this
rainfall is very important for sustaining agriculture. It helps in sowing of
rabi crop and also beneficial for plantation crops of Tea and coffee
