Ozone depletion in ongoing, and has been since the 1700s. Some processes require visible light (so "daytime"), some do not ("anytime").
Ozone started depleting because of CFC's. They react with ozone.
The depletion of ozone depletion is a seasonal phenomenon. It occurs mainly in winters.
The ozone depletion is not a natural process. If the man made processes depleting the ozone are stopped then there will be no depletion of ozone to cause an ozone hole.
The ozone depletion is the lowering of ozone molecules. It is the depletion of the molecules due to the depleting substances used. Freons are one such depleting substances.
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 process that causes CFC's to damage the ozone layer is called depletion. It is happening in the ozone.
See "What is the depletion of the ozone layer?" in the "Related questions" section below.
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.
