Cfcs Cause Deterioration of the Ozone Layer

Cfcs Cause Deterioration of the Ozone Layer

     The deterioration of the ozone layer , caused by Cfcs, endangers the
lives of humans'.  Cfcs have a diminishing effect on the ozone layer.
Furthermore, the  deterioration of the ozone cause an increase of  Ultraviolet
(UV) radiation which can have a negative effect on human skin and eyes.  As a
writer for newsweek, I have investigated the scenario and found the following
information.
     The earth's atmosphere is a blanket of air that surrounds the planet.
This atmospheric air is made up of many different gases, 78% nitrogen, 21%
oxygen, and 1% of a dozen or more other gases like carbon dioxide, helium, and
ozone.
     This atmosphere extends many miles out from the earth's surface.
However, this layer is not a uniform layer, from top to bottom.  As one moves
out from the planet's surface the atmosphere becomes progressively dense. This
atmosphere can be divide into four major regions.
     The first region is the troposphere which extends about 6.5 miles above
the planet's surface.  The troposphere contains the oxygen that we breath and is
where a majority of our weather takes place.
     Beyond the troposphere is the second region of the atmosphere, the
stratosphere.  The stratosphere extends from roughly 6.5-30 miles from the
earth's' surface.  The air on this region is much less dense than in the
troposphere, and it's a lot drier.  The stratosphere is the area that contains
the majority of the ozone layer.
     Past the stratosphere is the mesosphere which extends to 50 miles above
the planet.  The last region is the thermosphere.  The thermosphere's outermost
edge is roughly 600 miles above the surface of the earth.  Beyond it, the
airless vacuum of space begins.
     Oxygen is made up of two oxygen atoms that are bonded together.  In the
periodic table it is represented by O2.
     Like  oxygen, ozone is a gas that is made up of oxygen atoms.  However,
a molecule of ozone is made up of three atoms of oxygen bonded together,
therefore, O3, represents ozone.  The ozone makes up only .01% of the atmosphere.
Furthermore, 90% of the ozone is found in the stratosphere.  It is concentrated
in a layer between 7 and 22 miles above the earth's surface.
     The massive depth of the ozone in the stratosphere would lead you to
believe that it  is very thick, it is not.  If it were condensed, the ozone
layer would only be a few millimeters thick (Rowland and Molina 1994. p.23).
     The ozone is made in th...
