Which of the following is true regarding the depletion of ozone in the ozonosphere?
A) The depletion is restricted to the arctic and antarctic regions.
B) It results from chemical reactions with chlorine derived from CFCs.
C) It results from the burning of fossil fuels.
D) The notion that ozone is being depleted as a result of human activity has little scientific evidence to support it.

Question

Quizplus · Accepted Answer

The depletion of ozone in the ozonosphere is primarily attributed to chemical reactions with chlorine derived from chlorofluorocarbons (CFCs) and other anthropogenic compounds. This process is more pronounced in the polar regions due to the unique meteorological conditions present there. The burning of fossil fuels, on the other hand, contributes to air pollution and climate change, but is not a direct cause of ozone depletion. Option A is incorrect because while the depletion is more severe in the poles, it occurs globally. Option D is also incorrect because there is overwhelming evidence to support the notion that human activity is causing ozone depletion.
