Why is the biggest ozone hole in Antartica which is a non polluting continent?

Answer 1

This occurs because of unique characteristics of the cold polar vortex that forms over the Antarctic in winter. As the winter wears on more and more of these reservoir compounds are converted in the polar vortex. When spring finally comes the concentration of reservoir compounds may be near zero while free CI has increased considerably. Spring brings the sun to the Antarctic and the process of ozone destruction begins and is accelerated by abundance of free CI, producing an ozone hole.
The same process does not occur in the northern hemisphere to the degree it does in the south due to differences in the Antarctic and arctic winters. However O zone holes have been observed in the arctic as well, indicating a worsening of the state of the ozone layer.

Answer 2

Take a cup of water, pour some sugar in it and swirl the water around for a minute or so. How's the undissolved sugar distributed? Is it in a little pile in the center of the bottom of the cup? That's grossly oversimplified, but the same basic idea - the air over the poles doesn't mix very well with the swirling air belts that go around the world. Pollutants including chlorofluorocarbons tend to accumulate there, and as a result ozone production gets cut back severely and the 'hole' doesn't get flushed out. Same with water-borne pollutants - long-lasting stuff is still showing up there from a long time ago (DDT, for instance).

Answer 3

actually there is hardly any population in antartica to produce pollutants like CFCs etc to deplite the ozone layer. but due advanced , developed coutry like america produces a large amount of pollution. the gases travel a long way and accumalates near antartica and thus the ozone layer here gets deplited.

Answer 4

I think
taking in to account the direction and the axis over which the earth spins
and also the directions of the air in the atmosphere

the pollution by the world rowdies

reach antartica automatically

Answer 5

Ozone is destroyed in the Antarctic spring by chlorine formed during the sunless winter. The chlorine is generated by an unusual reaction between stable molecules, on the surface of small stratospheric cloud particles which can only form in the intense cold of the polar winter. The stable molecules obtain their chlorine from CFCs which have previously been broken up in sunlit regions

Answer 6

Some people have danced around the answer, but not exactly. The deterioration of the ozone layer was caused by CFCs (chlorofluorcarbons). After being produced around the world, the world's natural meteorological patterns shift the CFCs up to the poles. There, several factors combine to make ozone-CFC reactions highly favourable.

I can't describe it very well, but this site will answer any questions you have.

Answer 7

I have no idea but it is an interesting point, why would Antartica with no industrial life have so little ozone, when loss in ozone is caused by the release of Co2 gas. What dose this say about the liberal global warming theroy... not alot dose it?

Answer 8

Contribution of the inhabited continents to the nature. Result of our greed. We learn our lessons only when it burns a hole in our head.

Answer 9

buzz

it is said that the ozone layer is thinnest above Antarctica, though the reason for that is unknown. so when the attack on CFCs came then the weakest link got destroyed first.

Answer 10

it is the place where the polar caps are most
and the polar caps from mainly from there starts to melt
