Quizplus · Accepted Answer

The hole in the ozone layer is primarily caused by Chlorofluorocarbons (CFCs). CFCs were commonly used in aerosol cans, refrigerants, and solvents. When released into the atmosphere, they break down into chemicals that can destroy ozone molecules in the stratosphere. The hole in the ozone layer is mainly thought to be caused by chlorofluorocarbons (CFCs) which were used in refrigerants, aerosol sprays, and foam products. When CFCs reach the stratosphere, they break down and release chlorine atoms which react with ozone, depleting its concentration, and creating a hole in the ozone layer above Antarctica.
