Ozone is formed in upper atmosphere by the reaction of ultraviolet (UV) radiations on oxygen (O2) molecule.
The damage to ozone layer is a cause of concern to us as due to its damage, more ultraviolet rays reach the earth’s surface causing various health hazards.
O2 → O + O
O2 + O → O3(Ozone)
A cause of this damage is the presence of large amount of chlorofluorocarbons in the atmosphere.
