[tags: ultraviolet rays, ozone moleculas] - Over the years scientists have discovered the main function of the ozone layer.They have found that the ozone layer naturally shields the Earth from ultraviolet radiation that in large amounts can be harmful.Water vapor, carbon dioxide and ozone then absorb much of this radiation and remit a large proportion back towards the earth....

Stratospheric ozone is found in a broad band, extending generally from 15 to 35km above the earth.

Although the ozone layer is surprisingly thin, it acts as a protective shield to the earth, as it filters out most of the harmful solar ultraviolet radiation (in particular UV-B) that would otherwise reach our planets surface....

It is the UV-B rays, between 280 and 320nm, absorbed only by ozone, that are of the greatest concern....

[tags: Meteorology Atmosphere Research Papers] - The Ozone Layer In environmental science the green house effect is a common term for the role water vapor; carbon dioxide and ozone play in keeping the earth’s surface warmer than it would normally be.

[tags: Struggles, Chemistry, History] - The Ozone Layer The stratospheric ozone layer exists at altitudes between about 10 and 40km depending on latitude, just above the tropopause.

Its existence is crucial for life on earth as we know it, because the ozone layer controls the absorption of a portion of the deadly ultraviolet (UV) rays from the sun.

The depletion of the ozone layer has and will continue to have many detrimental effects on all living things on this planet.

A thinner layer will allow more of the sun’s ultraviolet radiation to reach the Earth’s surface.

UV-A rays, including wavelengths between 320 and 400nm, are not affected by ozone.

UV-C rays between 200 and 280nm, are absorbed by the other atmospheric constituents besides ozone.

Ozone is a highly irritant gas, which is formed in our atmosphere in the presence of sunlight from other air pollutants, including nitrogen oxides and hydrocarbons....
