There are seasonal variations in the ozone layers; in springtime, there is less ozone in the ozone layer over the polar regions, esp ...
7 de oct. de 2021 · Ozone Depletion. When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules. One chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere. Ozone can be destroyed more quickly than it is naturally created.
