With reference to Ozone hole, consider the following statements:
1. Ozone hole refers to a region in the troposphere where the concentration of ozone becomes extremely low.
2. Ozone holes are most commonly found over the Antarctic region because it experiences strong polar vortex.
Which of the statements given above is/are correct?
Explanation:
Solution. Exp: Statement 1 is not correct:Ozone holes refers to a region in the stratosphere where the concentration of ozone becomes extremely low especially in the winters when polar vertex strengthens. Statement 2 is correct: Ozone holes are most commonly found over the Antarctic region because it experiences strong polar vortex.The unique cocktail of the powerful polar vortex and low temperatures generates stratospheric clouds that react with CFCs and destroy the Ozone layer in the process.
