Ozone is a gas in the lower level of stratosphere. It is a kind of super-charged oxygen (O3). It makes a layer in the atmosphere which acts as a cover to the Earth against ultraviolet radiation of the Sun. The canopy of ozone layer is with variable extent less dense near the surface of the Earth compared to the height of 30 km.
Some pollutants in the atmosphere like chlorofluoro-carbons (CH3) cause the depletion of ozone layer. These CFCs and other similar ‘gases when reach to the stratosphere they are broken down by the ultraviolet radiation and as a result they liberate free atoms of chlorine or bromine. These atoms are highly reactive with ozone and disrupt the stratospheric chemistry. The reactions deplete ozone layer.
