Ozone layer depletion is directly related to which atmospheric layer?
Answer and explanation
Correct answer: Stratosphere
Option B is correct because the greatest concentration of atmospheric ozone is found in the stratosphere, especially in the ozone layer several kilometres above Earth’s surface. Ozone absorbs harmful ultraviolet radiation, and chemicals such as chlorofluorocarbons can participate in reactions that destroy ozone there. The troposphere contains some ozone as a pollutant, but it is not the main protective ozone layer. Mesosphere and exosphere are not the direct focus of ordinary ozone-layer depletion, so C and D are incorrect.
