Ozone depletion describes two related phenomena observed since the late 1970s: a steady decline of about four percent in the total amount of ozone in earth's stratosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around earth's polar regions. [toc] what is the ozone layer ozone is a naturally occurring molecule containing three atoms of oxygen ozone molecules form a gaseous layer mostly in the upper atmosphere (the stratosphere) 15-30 km above the surface of the earth. 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.

How to protect the ozone layer stratospheric ozone, otherwise known as the ozone layer, is a layer of gas (o3) that partially shields the earth from the sun's ultraviolet (uv) radiation.
The ozone layer was discovered in 1913 by the french physicists charles fabry and henri buisson its properties were explored in detail by the british meteorologist g m b dobson, who developed a simple spectrophotometer (the dobsonmeter) that could be used to measure stratospheric ozone from the. Ozone layer and causes of ozone depletion: ozone layer is a deep layer in earth's atmosphere called stratosphere that contain ozone which is a naturally occurring molecule containing three oxygen atoms. What is the ozone layer made of question date: 2005-11-08: answer 1: the ozone layer, also called the stratosphere, is composed of the ozone gas (90% of the total ozone in the atmosphere. Stratospheric ozone depletion, an environmental crisis in the 1980s, can now be considered an environmental triumph thanks to global cooperation in combating it. The ozone layer is the part of the earth's atmosphere which contains relatively high concentrations of ozone (o3) relatively high means a few parts per million - much higher than the concentrations in the lower atmosphere but still small compared to the main components of the atmosphere.

The ozone layer is a chunk of the atmosphere located anywhere between 15 km and 35 km above the surface of the earth the name is a slight misnomer as the percentage of ozone (an allotropic form of oxygen) in the layer is only a few parts per million however, over ninety percent of the free natural ozone in the atmosphere is. 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 is important because it filters harmful ultraviolet radiation as it travels from the sun to the surface of the earth these. Watch video for the first time, scientists show the ozone layer is on the road to recovery.
Thinning of the protective ozone layer can be observed using satellite measurements, particularly over the polar regions how does. In new analysis, scientists detect shrinking of the planet’s protective shield at lower levels of the stratosphere over earth’s nonpolar regions. Definition of ozone layer: belt of ozone gas 15 to 50 kilometers above the earth's surface where ozone is present in concentrations of a few parts per million.
The ozone layer or ozone shield is a region of earth's stratosphere that absorbs most of the sun's ultraviolet (uv) radiation it contains high concentrations of.
Define ozone layer: an atmospheric layer at heights of about 20 to 30 miles (32 to 48 kilometers) that is normally characterized by high ozone. Ninety percent of the ozone in the atmosphere sits in the stratosphere, the layer of atmosphere between about 10 and 50 kilometers altitude the natural level of ozone in the stratosphere is a result of a balance between sunlight that creates ozone and chemical reactions that destroy it ozone is. The ozone layer is found out in the stratosphere region of theatmosphere this layer protects us from the harmful uv rays of thesun. The function of the ozone layer is to shield the earth from the harmful ultraviolet rays of the sun and to keep the earth warm the ozone layer is composed of ozone, a molecule made up of three.
