Chlorofluorocarbons (CFCs) are known to cause the depletion of the ozone layer in the upper atmosphere.
Which statement is a correct description of this process?
CFCs are broken down by infrared radiation to release chlorine radicals.
Chlorine radicals act as catalysts in the breakdown of ozone.
The depletion of ozone increases the greenhouse effect by trapping more heat in the atmosphere.
A single chlorine radical can destroy only one ozone molecule before it is terminated.
