The ozone depletion process begins when CFCs and other ozone-depleting substances (ODS) are emitted into the atmosphere(1). Winds efficiently mix the troposphere and evenly distribute the gases. CFCs are extremely stable, and they do not dissolve in rain. After a period of several years, ODS molecules reach the stratosphere, about 10 kilometers above the Earth's surface (2).
Strong UV light breaks apart the ODS molecule. CFCs, HCFCs, carbon tetrachloride, methyl chloroform, and other gases release chlorine atoms, and halons and methyl bromide release bromine atoms (3). It is these atoms that actually destroy ozone, not the intact ODS molecule. It is estimated that one chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere (4).
There are many myths. One such is that ozone is located in ozonosphere and another is that ozone layer damages us.
The ozone depletion process began in the late 1970s and early 1980s with the discovery of the Antarctic ozone hole. This led to the realization that human activities, specifically the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances, were contributing to the thinning of the ozone layer.
Ozone depletion occurs in the ozone layer.
Global warming and ozone depletion are not related.
Ozone depletion is the thinning of ozone layer below a certain concentration. This phenomenon is termed as ozone depletion.
Ozone depletion is the process of thinning of ozone molecules below a certain concentration. The main reason behind ozone depletion is the excessive use of CFCs.
Ozone depletion is the process where ozone holes are formed due to the action of CFC's and other chemicals. It is very harmful.
Ozone depletion is the process where ozone holes are created in the ozone layer. It is caused due to the action of chloro-floro-carbons on the ozone molecule to break it down to oxygen.

The ozone depletion is caused by natural or man made processes. Man made process is the releasse of CFC's by humans.
