What causes CFCs to release chlorine?
What causes CFCs to release chlorine?
CFCs are made up of chlorine, fluorine and carbon atoms. When these CFCs are released into the atmosphere and brought up to the stratosphere by strong winds the ultraviolet radiation from the sun hits the CFC molecule. This causes a chlorine atom to break apart from the chlorine molecule.
How do CFCs break down?
Once in the atmosphere, CFCs drift slowly upward to the stratosphere, where they are broken up by ultraviolet radiation, releasing chlorine atoms, which are able to destroy ozone molecules.
Why does ozone react with chlorine?
Chlorine is able to destroy so much of the ozone because it acts as a catalyst. Chlorine initiates the breakdown of ozone and combines with a freed oxygen to create two oxygen molecules. After each reaction, chlorine begins the destructive cycle again with another ozone molecule.
