Ozone Layer Environment

The ozone layer is a layer in the Earth's atmosphere which contains relatively high concentrations of ozone (O3). This layer absorbs 93-99% of the sun's high frequency ultraviolet light, which is potentially damaging to life on Earth. It is mainly located in the lower portion of the stratosphere from approximately 10 km to 50 km above Earth's surface.
