Question

Quizplus · Accepted Answer

Chlorofluorocarbon (CFC) gases used in refrigeration are the primary cause of the breakdown of the ozone layer. When released into the atmosphere, they react with and break down ozone molecules, leading to the thinning of the ozone layer. Carbon dioxide, sulfuric acid, and unburned hydrocarbons do not have a direct impact on the ozone layer, although they can contribute to other environmental problems such as climate change and air pollution.
