Answer
- The area in Antarctica region with a thin ozone layer is known as ozone hole.
- $ \text{CFCs }($chlorofluorocarbons$)$ which $-$are widely used as refrigerants disturb the balance between the production and degradation of ozone.
- Ultraviolet $(UV)$ rays and chlorofluorocarbons $ \text{(CFCs)}$ release chlorine $(Cl^–)$ ions which act as catalyst in the degradation of ozone layer.
- Chloride ions also degrade the ozone layer.
- The degradation of ozone layer results in the depletion of ozone causing a hole in the ozone layer.
