Answer to Question 1
B
Answer to Question 2
Ozone (O3) molecules absorb ultraviolet radiation, but split into oxygen gas (O2) and molecular oxygen (O)during the process.These products recombine to once again form ozone molecules. This cycle is disrupted by pollutants such as CFCs and nitrogen oxides,CFCsbreak apart in the stratosphere and form chlorine atoms that react with ozone to form ClO and O2that will not recombine to form ozone. Nitrogen oxides in the form of NOx also destroy molecules of ozone in the stratosphere. Over the South Pole, conditions are right for pollutants to greatly diminish ozone concentrationsthrou gh chemical reactions, thus producing the Antarctic ozone hole.
