Abstract


Our atmosphere is divided into different strata above the earth’s surface. The region closest to earth’s surface is the troposphere that is extended upto 10-16 km above the surface. This layer or strata is followed by stratosphere which extends upto nearly 50 km. Above it is the mesosphere region, which covers about 50-85 km from surface of the earth. Beyond the mesosphere lies the thermosphere which goes from 85-500 km away from the earth’s surface. The chemical composition in these layers varies considerably and so does the chemical reactions.
