What is the Ozone Hole?
The ozone hole is a well-defined, large-scale destruction of the ozone layer over Antarctica that occurs each Antarctic spring. The word “hole” is misnomer; the hole is really a significant thinning, or reduction in ozone concentrations, which results in the destruction of up to 70% of the ozone normally found over Antarctica. The A hole or A thinning of the ozone layer is a result of a heat catalyzed reaction between Chloroflorocarbon and Ozone that breaks it down into atmospheric oxygen (O2) and an oxygen radical. Once ozone is broken down, it takes a much more energy and time to react back into its original form.
