The ozone layer or ozone shield refers to a region of Earth`s stratosphere that absorbs most of the Sun`s UV radiation. It contains high concentrations of ozone (O3) relative to other parts of the atmosphere, although it is still very small relative to other gases in the stratosphere. The ozone layer contains less than ten parts per million of o.....

An atmospheric layer that contains a high proportion of oxygen that exists as ozone. It acts as a filtering mechanism against incoming ultraviolet radiation. It is located between the troposphere and the stratosphere, around 9.5 to 12.5 miles (15 to 20 kilometers) above the earth's surface.

An atmosphere layer at about 20 to 30 miles high (32 to 48 km), normally characterized by high ozone content, which blocks most solar UV radiation from entering the lower atmosphere.

A part of the Earth`s atmosphere that absorbs a proportion of ultraviolet light in incoming radiation, thus protecting the earth from its harmful effects. However, the ozone layer is being depleted by certain chemicals, so more ultraviolet light is reaching the Earth`s surface, contributing to global warming and to an increase in cataracts and skin...

a layer of air 15-50 km above the Earth's surface, where most atmospheric ozone is found. It absorbs some of the ultraviolet radiation of the Sun, and in doing so grows warmer and serves to lessen the ultraviolet received at the earth's surface. It is being depleted to some extent by a complex sequence of reactions involving man-made emissions from...

is a thin layer of stratoshere - between about 15 kilometres out and 50 kilometres out from the earth. The ozone layer was formed by oxygen from plants reacting with ultraviolet light of the sun. Concentration of ozone is heaviest between 25-35 km, but is almost certainly being depleted by pollution with CFCs.

An atmospheric layer that contains a high proportion of oxygen that exists as ozone. The ozone is created by a series of processes beginning with the splitting up of the oxygen molecule to single oxygen atoms. It acts as a filtering mechanism against incoming ultraviolet radiation. It is located between the troposphere and the stratosphere, around ...

About 90% of the ozone in the Earth's atmosphere is found in a layer between 22 and 30 km above the surface. This layer is within a region of the atmosphere called the stratosphere. The stratosphere is a stable layer of the atmosphere where exchanges with the lower atmosphere or troposphere are minimal. Ozone is naturally formed here through the ac...
