Ozone forms readily in the stratosphere as incoming ultraviolet radiation breaks molecular oxygen (two atoms) into atomic oxygen (a single atom). In that process, oxygen absorbs much of the ultraviolet radiation and prevents it from reaching the Earthâs surface where we live.

Ozone is formed by photochemical reactions occurring in the stratosphere. These reactions primarily occur high in the atmosphere because the UV light that drives them is completely absorbed in the stratosphere. We call this type of UV light UV-C. The UV-C light carries enough energy to break apart the oxygen molecule.
