ATMOSPHERIC AIR
Gases in the atmosphere are held in an envelope around the earth by gravity. The atmosphere is 80 km thick and is divided into four layers, namely troposphere, stratosphere, mesosphere, and thermosphere. About 75% of mass is found in the layer nearest to earth, the troposphere. Components of the Atmospheric Air Atmospheric air definition
