Question

Where does the ozone hole occur?

(a) North pole

(b) South pole

(c) The arctic

(d) Stratosphere

I got this question at a job interview.

I'm obligated to ask this question of Environmental Chemistry topic in chapter Environmental Chemistry of Chemistry – Class 11

Answer 1

The correct choice is (b) South pole

The best I can explain: In the 1980s, depletion of ozone layer, known as ozone hole, over the South Pole. In the summer season, NO2 and CH4 react with chlorine monoxide and chlorine atoms forming chlorine sinks, preventing much ozone depletion. In winter season, special clouds called polar stratospheric clouds are formed over Antarctica.
