Which of the following is true of chlorofluorocarbons?
A)The CFC molecules react with ultraviolet light to release carbon which then destroys ozone.
B)The CFC molecules react with ultraviolet light to release fluorine which then destroys ozone.
C)The CFC molecules react with ultraviolet light to release chlorine which then destroys ozone.
D)Most of the CFC-induced ozone destruction is occurring near the equator,rather than near the poles.
E)CFCs production will be phased out by 2026,but still continues in China and the U.S.

Question

Quizplus · Accepted Answer

CFC molecules contain chlorine atoms which react with ultraviolet light to release free ozone molecules, causing a reduction in the ozone layer. This process primarily occurs in the polar regions, where colder temperatures allow for the formation of polar stratospheric clouds that facilitate the release of chlorine from CFCs. While the production of CFCs has been phased out, they have a long atmospheric lifetime and continue to be present in the atmosphere, including in China and the U.S.
