Chlorine directly absorbs UV radiation, preventing it from reaching ozone.

Chlorine catalyzes the conversion of ozone ($O_3$) back into oxygen ($O_2$), without being consumed in the process.

Chlorine combines with ozone to form stable, harmless compounds.

Chlorine increases the rate at which ozone is naturally produced.

A process that cools the Earth's surface.

A natural process where heat is trapped near Earth's surface.

A phenomenon caused solely by human activities.

The depletion of the ozone layer.
