Question

explain depletion of ozone layer

Answer 1

HERE IS YOUR ANSWER.........

Answer 2

The main cause of ozone layer depletion is the build-up of CFCs (chlorofluorocarbons) in the atmosphere. When the CFCs reach the upper atmosphere, high UV radiation reacts with these and releases chlorine atoms. These free chlorine atoms react with ozone thereby leading to the depletion of the ozone layer.

One chlorine atom can destroy millions of ozone atoms before it decomposes and this is why CFCs are extremely damaging to the ozone layer.It is caused by many applications like the production of refrigerants, anesthetics, aerosol sprays.
