What is ozone thinning?

Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 4

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.

Answer 5

CFC's are causing ozone thinning. They react with ozone and deplete it.

Answer 6

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.

Answer 7

The thinning of ozone layer is termed as ozone depletion. it is the falling of concentration of ozone layer below a certain limit.

Answer 8

It is depletion of the ozone layer

Answer 9

That is called ozone depletion, my friend
