Ozone provides protection from ultraviolet radiation.

Explanation:

Ozone which is a form of Oxygen #O_3# absorbs about 98% of harmful ultraviolet radiation. The ozone layer is in the stratosphere. Nitrogen also absorbs very high energy ultraviolet.

The ultraviolet breaks down Oxygen #O_2# and ozone #O_3# releasing heat. The concentrations of Oxygen and ozone are preserved by the reaction.

Ozone is very effective at preventing the more dangerous forms of ultraviolet from reaching the surface of the Earth.
