OZONE layer: It is a thin layer of Earth ATMOSPHERE, which protects us from ultra-violet rays resides at the stratosphere. Ozone is made of THREE molecules of oxygen (O3).Ozone depletion i.e. gradual thinning of Earth’s ozone layer in the upper atmosphere caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities.The depletion of the ozone layer RESULTS in an increase in the earth's atmospheric temperature.Chlorofluoro Carbons (CFCs) and some Halogens are the chemicals that break the ozone into simple oxygen.CFCs are found in aerosols, paints, and refrigerants. Nowadays government bans CFCs compounds.Ozone gas is a poisonous gas.Explanation:THEREFORE, Pollutants that are responsible for the depletion of the ozone layer are chlorofluorocarbons.
