Quizplus · Accepted Answer

Chlorofluorocarbons (CFCs) have a long atmospheric lifetime of 50-100 years, which allows them to spread globally and be transported into the stratosphere. Once in the stratosphere, they break down and release chlorine atoms that can destroy ozone molecules, leading to the formation of the ozone hole.
