In which layer of the atmosphere does ozone absorb the most UV radiation?
Troposphere
Stratosphere
Mesosphere
Thermosphere
Stratosphere
Most ozone (about 90%) is found in the stratosphere, which begins at about 10โ16 kilometres above Earth`s surface and extends to an altitude of about 50 kilometres. Ozone in the stratosphere protects life on Earth from harmful ultraviolet (UV) radiation and is therefore often called good ozone.
