How is ozone hole depleted? Mention any two harmful effects of ozone depletion.
Answers
Answer:
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.
Two harmful effects of ozone depletion are :
(i) Due to depletion of ozone layer, UV radiation reaches the earth. These UV radiation causes skin cancer, damage to eyes and immune system. (ii) This depletion of ozone layer may also lead to variations in global rainfall, ecological disturbances and dwindling of global food supplies.
