Answer :
Atmosphere of the Earth is composed of many layers. The first layer is the troposphere, it extends approximately 10 kilometres upwards from the earth’s surface. The human activities such as flying of balloons, mountain climbing, and small aircraft flights take place in this layer.
The layer above the troposphere is the stratosphere which extends up to 60 kilometres. The ozone layer is present in stratosphere from about 20-30 kilometres above the earth’s surface. The ozone layer is about 3 to 5 mm thick. Ozone is composed of 3 oxygen atoms (O3). The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson.
The ozone layer has the ability to absorb harmful ultraviolet radiations (UV radiations) coming from the Sun. therefore, ozone protects life on earth from strong ultraviolet radiations. The ultraviolet rays are harmful rays that can cause skin cancer, cataracts and damage the human defence to fight diseases (immune system). Ultraviolet rays are also capable of destroying l plant life, and aquatic life.
