This is a thinning (by about 2/3, of the ozone over the Antarctic during the spring time, towards the end of the long winter night in the south pole. There is no actual hole in the layer.
This has occurred for centuries, in fact the thinnest we know the layer has ever been is in 1858, before man started using cfc's.
A similar thinning occurs, to a much smaller extent in the Arctic during the end of it's winter night also. The thinning is much smaller in the Arctic and NASA even reffers to this thin area as the "Dimple" due to the small size.
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.
Thinning of ozone layer is the depletion of ozone molecules by natural or man made factors. The place where this thinning is prominent is called ozone hole.
The thinning of ozone layer is the falling of concentration of ozone concentration in the ozone layer below a certain concentration. It is termed as ozone depletion.
CFC's are causing ozone thinning. They react with ozone and deplete it.
The thinning of ozone layer is the falling of ozone molecules below a concentration level. This thinning has been named ozone hole. It is caused due to the ozone depleting substances.
The thinning of ozone layer is termed as ozone depletion. it is the falling of concentration of ozone layer below a certain limit.
It is depletion of the ozone layer
That is called ozone depletion, my friend
CFC's cause thinning of ozone. They react with ozone to deplete it.
Thinning of ozone can be reversed by reducion of CFC's. If CFC's are reduced, there will be no more thinning.
The weakening of ozone layer is due to its thinning. The ozone is thinning because of the attack of ozone depleting substances on it.
The thinning of ozone layer. When this thinning reaches a certain concentration then it is ozone hole.
It can be reversed but not quickly. Ozone thinning will be reversed gradually and slowly.
CFC's cause thinning of ozone. They react with ozone to deplete it.
CFC's are responsible for thinning of ozone. They react with ozone to thin it.
Thinning of ozone can be reversed by reducion of CFC's. If CFC's are reduced, there will be no more thinning.
The thinning of ozone layer is the depletion of certain amount of molecules of ozone in the ozone layer. This is a harmful phenomenon.
The weakening of ozone layer is due to its thinning. The ozone is thinning because of the attack of ozone depleting substances on it.
The thinning of ozone layer. When this thinning reaches a certain concentration then it is ozone hole.
The reduction in concentration of ozone molecules is the thinning. It is caused by CFC's.
CFC's are causing its thinning. They react with ozone to deplete it.
It can be reversed but not quickly. Ozone thinning will be reversed gradually and slowly.
The thinning of ozone layer is mainly due to man made ozone depleting substances. They react with ozone and decompose it.
The thinning of ozone overall is called ozone depletion. It can be due to a number of factors.
If the ozone is thinning, it will lead to ozone hole. It allows the harmful UV to pass through.
