• The chlorofluorocarbons are released into the air.
• The CFCs reach the ozone layer after passing through the stratosphere, and troposhere.
• Ultraviolet rays hit the CFC particles and turn it into chlorine monoxide.
• The chlorine monoxide molecules jump around, destroying many of the ozone molecules.

A CFC molecule has to pass through all the layers of the atmosphere, stratosphere, troposhere, ionosphere, and mesosphere. Look at the picture to see all the layers.

Did you know that one chlorine monoxide are so dangerous that 100,000 ozone molecules can be killed by a single chlorine monoxide? The use of having CFC in aerosol sprays are banned from the United States. A few years ago, scientists discovered a big hole in the ozone above Antarctica. Recently, a similar hole was discovered and it covered Scandinavia, the Arctic, and North America. Some other chemicals that destroy the ozone layer are carbon tetrachloride, methyl chloroform, and other chloride based chemicals.

In the atmosphere, small amounts of carbon dioxide make the greenhouse effect. The carbon dioxide lets the suns heat go in, but not come out. However, the amount of carbon dioxide has doubled and may cause global warming. The trees help destroy some of the carbon dioxide, but as we cut the trees down, more and more carbon dioxide goes into the atmosphere. This may result in global warming. The result of global warming may melt the ice caps and cause coastal cities to flood. For a solution, you shouldn't use many materials with CFCs in them.
