Heya!!

The atmosphere is vital for life on the earth. 
It helps sustain life in many ways. 
The  atmosphere acts as a blanket by trapping the terrestrial radiation and keeping the earth warm. 
If it were not for this, all the life forms on Earth would have been either burnt during the day or frozen to death during the night.

• While the atmosphere permits the solar radiation to enter the biosphere, it prevents the harmful ultra violet rays, from entering the biosphere.

• The mass of air also moves about to maintain the natural thermal balance making the   planet earth livable.

• The atmosphere contains oxygen, the gas living beings need to breathe to stay alive.

• The moisture it contains is an essential part of the water cycle.

• Green plants need the carbon dioxide present in the atmosphere for making food.
