Monsoon:India 's angel



Monsoon is greatest  boon to india ,it nurtures our mind with joy by making  landscape green and source of food by irrigating agricultural land.
Summer leads to Monsoon?
Earth geography causes Summer .We know that earth tilt by 23.5 degrees from its axis rotating around the sun which makes seasons on the earth(Summer,winter).
Tilt happen in two direction.one is tilt of earth towards sun making steep sun rays  to hit on north hemisphere (Upper half part of globe )  and tilt of earth away from the sun making steep sun rays hit on south hemisphere (Lower half part of the globe).When north hemisphere tilt towards sun the countries which lie is north hemisphere(Upper half part of globe) gets steep sunlight which causes summer, at the same time south  hemisphere countries will be under winter season beacuse these regions will get shallow sunlight .

Monsoon:
In summer (april and may)  Thaar desert and middle India gets  intense  steep sun rays thus  air will  warm up and loses its density , move to  upper area of atmosphere making low pressure zone .To fill the void (gap) moisture  laden winds from the ocean will rushes to land which  leads to rain.Monsoon winds reach lands of India at the end of May.
