Ozone layer - Wikipedia
The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains high concentrations of ozone (O 3 ) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.

Ozone Layer Protection | US EPA
The stratospheric ozone layer is Earth’s “sunscreen” – protecting living things from too much ultraviolet radiation. The emission of ozone depleting substances has been damaging the ozone layer.

Ozone Depletion Information and Facts, Ozone Layer, Ozone Hole
The ozone layer is a belt of the naturally occurring gas "ozone." It sits 9.3 to 18.6 miles (15 to 30 kilometers) above Earth, and serves as a shield from the harmful ultraviolet B (UVB) radiation emitted by the sun.

ozone layer | Description, Importance ... - Britannica.com
Ozone layer, also called ozonosphere, region of the upper atmosphere, between roughly 15 and 35 km (9 and 22 miles) above Earth’s surface, containing relatively high concentrations of ozone molecules (O 3).

The Ozone Hole
The Ozone Layer. The ozone layer is a layer in Earth's atmosphere which contains relatively high concentrations of ozone (O3). This layer absorbs 97-99% of the sun's high frequency ultraviolet light, which is potentially damaging to life on earth.

Basic Ozone Layer Science | Ozone Layer Protection | US EPA
Learn about the ozone layer and how human activities deplete it. This page provides information on the chemical processes that lead to ozone layer depletion, and scientists' efforts to understand them.

The Ozone Layer - NASA Advanced Supercomputing Division
"The ozone layer" refers to the ozone within stratosphere, where over 90% of the earth's ozone resides. Ozone is an irritating, corrosive, colorless gas with a smell something like burning electrical wiring.

Ozone layer shows signs of healing - CNN
The Antarctic ozone layer, which shields the Earth from harmful ultraviolet rays, shows encouraging signs that it's beginning to heal, according to research.
