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.
Major ozone problems occur in stratosphere. It is where the ozone is located.
The ozone depletion refers to the thinning of ozone layer due to a no. of factors which include the man made and the natural ones. The natural depletion does not contribute to the ozone hole as the rate of formation of ozone hole is in equilibrium with the depletion. However due to the use of the harmful chlorofluorocarbons by the human beings the rate of depletion of ozone is increasing considerably thus leaving the rate of formation far behind. This difference in the formation rate and depletion rate leads to ozone hole.
Ozone depletion occurs by CFC's. they react with ozone to deplete it.
See "How did the ozone hole occur?"
Ozone production occours in stratosphere. It is present as ozone layer.
No they don't. Animals do nothing to harm ozone.
Yes.
Stratospheric ozone is present in ozone layer. It occurs because of UV.
During the creation of ozone, the UV decomposed the oxygen. This oxygen then was created to ozone.
The ozone hole can be found at cold areas. Thus ozone hole can be found out at the poles mainly.
The ozone hole exists above Antarctica from August to November
It is because of the CFC's. They react with ozone and deplete it.
