Question

Quizplus · Accepted Answer

Chlorofluorocarbons (CFCs) are synthetic compounds that were once widely used in refrigeration, air conditioning, and aerosol sprays. When released into the atmosphere, they react with and deplete the ozone layer. Carbon dioxide (A) is a greenhouse gas that contributes to global warming, but it is not directly linked to the breakdown of the ozone layer. Nitrogen oxides (C) are involved in the formation of acid rain and smog, but they do not play a significant role in ozone depletion. Water vapor (D) is a natural component of the atmosphere and does not have a direct impact on the ozone layer. Infrared radiation (E) is a type of electromagnetic radiation that transfers heat, but it is not a substance that directly affects the ozone layer.
