Ozone is a gas that is composed of three atoms of oxygen.
The ozone layer serves a important purpose. It absorbs a band of ultraviolet radiation called UVB, which is particularly harmful to living organisms, such as humans. A healthy ozone layer prevents most UVB from reaching us, however. Chlorofluorocarbons, or CFCs are compounds that consist of chlorine, fluorine, and carbon. The combination of UVB in the ozone and CFCs in the same area creates a cause and effect cycle.
