Describe the relationship between cfcs and the earth’s protective ozone layer

The relationship between CFCs and ozone layer is that the release of CFCs in the atmosphere harms or depletes the ozone layer

Explanation:

CFCs or chlorofluorocarbons are made up of chemical compounds like carbon,fluorine and chlorine. They are used as important refrigerants and solvents in the manufacturing of refrigerators, ACs, coolers and aerosols sprays. When it is released in the environment due to improper appliance disposal or leakages it goes high up in the atmosphere where it is broken down by the UV rays and then the chlorine atoms released after this process attack the ozone molecules and destroy them. Therefore, depleting the ozone layer.
