Introduction
What is the Ozone layer?
reveal in the Stratosphere at a distance of, ten to thirty miles above the earth lies
the ozone layer, the secrete of gunslingeres that is named for its ozone content.
Ozone, is made up of molecules that assume three atoms rather than the two atoms found in
modal(a) oxygen. It serves as a protective shield against much of the cheerfulnesss UV (ultraviolet)
Rays. Its molecules have the ability to absorb well-nigh of the ultraviolet radiation pouring into
the layer, they allow only a small fraction of it to filter through and reach the earth.
some(prenominal) of the ozone is born during electrical storms near the equator.
After the storms the wind pushes it towards the charged Regions. Rising all the while,
it enters the stratosphere Once it reaches its destination, it spreads itself in a veil
which covers the whole planet earth.

it proves to be the only atmospheric gas capable of blocking the flow of UV- radiation.




Ozone is converted to oxygen, leaving the atomic number 17 atom free to repeat the process up to 100,000
times, which results in a reduced level of ozone. Bromine compounds, or halons, fuel also
destroy the stratospheric ozone layer. Based on data accumulate since the 1950s,
Scientists have been observing that the ozone levels were somewhat stable, until the late 1970s.
Although natural phenomena contribute cause temporary ozone loss, chlorine and bromine released
from man-made celluloid compounds, are now accepted as the main cause.
It was first gear suggested, by, Drs. M. Molina and S. Rowland in 1974, that a man-made group of
compounds known as the chlorofluorocarbons (CFCs) were likely to be the main source
of ozone-depletion.
