Composition of Air - For thousands of years, air was considered to be a mixture of many gases. The true composition of air was not known for a long time. Air is a mixture of various gases. The main gases present in air are nitrogen (78.1% by volume) and oxygen (20.9% by volume)...

. This zone is called troposphere. Therefore, at higher altitudes, some of us find it difficult to breathe. Above the troposphere is the stratosphere. This zone is rich in ozone. Hence, it is also called ozonosphere. In ozonosphere, the sunlight converts oxygen to ozone by photochemical dissol..
