Most ozone resides in the stratosphere (a layer of the atmosphere between 10 and 40 km above us), where it acts as a shield to protect Earth's surface from the sun's harmful ultraviolet radiation.
The ozone layer is a region in the Earthâs atmosphere that contains high concentrations of ozone. Ozone is three molecules of oxygen bonded together, and so it has the chemical symbol O 3. The ozone layer contains more than 91% of the ozone in the Earthâs atmosphere.Because it absorbs ultraviolet radiation from the Sun, the ozone layer is vital to the evolution and survival of life on Earth.zone is three molecules of oxygen bonded together, and so it has the chemical symbol O 3.
