1.	In winter season, special type of clouds called polar stratospheric clouds are formed over Antarctica. As a result, less depletion of ozone layer takes place due to reactions
Answer» `CIONO_(2)+H_(2)O rarr HOCI+HNO_(3)` `CIONO_(2)+HCl rarr Cl_(2)+HNO_(3)` both (a) and (B) none of the above Solution :Polar strtospheric clouds PROVIDE surface on which `ClONO_(2)` is HYDROLYSED (in (a)), `ClONO_(2)` changes to molecular `Cl_(2)` in (b) Thus, ozone LAYER depletion is prevented.
