When the UV radiations from sun strike the O2 molecules, it causessplitting of O2. Oxygen molecules react with oxygen atoms in the upper atmosphere to form ozone. ... Ozone layer is also naturally broken down but there is a balance between its formation andnatural depletion.
Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). ... CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone's ultraviolet radiation-absorbing capacity.
