Where is the majority of Earth's ozone located?

Explanation:
Ozone is most abundant in a specific atmospheric layer that protects life by absorbing harmful UV radiation. In the stratosphere, roughly 10 to 50 km above the surface, ozone concentrations are highest, forming the ozone layer with a peak around 20–25 km. The conditions there favor ozone buildup, while the troposphere has ozone too but in much smaller amounts and it often acts as a pollutant near the ground. Above the stratosphere, in the mesosphere and exosphere, ozone is present only in trace amounts.
