What Is Ozone Layer?
A layer high in the stratosphere with extra ozone that blocks most of the Sun's harmful ultraviolet light. In technical terms: The region of the stratosphere, roughly 15-35 km, where ozone concentration peaks (around 8-10 ppm); absorption of UV radiation there heats the stratosphere and produces its temperature inversion.
