Atmosphere: This comprises a blanket of gaseous layer around earth. Ozone layer is one of the important constituents of stratosphere.The presence of ozone in the stratosphere prevents about 99.5 per cent of the sun’s harmful ultraviolet (UV) radiations from reaching the earth’s surface and thereby protecting humans and other animals from its effect. It has also been reported that plant proteins get easily affected by UV radiations which leads to the harmful mutation of cells.
