What is the Ozone Layer?
The ozone layer is a region of the Earth's stratosphere that contains a high concentration of ozone (O3) molecules. It acts as a shield, absorbing most of the sun's ultraviolet (UV) radiation that would otherwise be harmful to life on Earth.
The ozone layer is located in the stratosphere, between about 10 and 30 miles above the Earth's surface.
