Why is the ozone hole occurring only on ANTARCTICA and Not at the places where there are TOO many CFC's?

Question

Hey so many answer whom shall i bbelieve eh?

Answer 1

There is a record hole over Antarctic this year

http://www.theozonehole.com/nasaandnoaa.htm

The Antarctic hole and thinning occurs in the Southern Hemisphere in their late winter and spring, August onwards.

The Arctic is affected similar to Antarctica but it is more a thinning of the ozone layer rather than a hole

The Arctic ozone thinning occurs in the Northern Hemisphere in our late winter and Spring so at present it is not affecting us but come February/March we will begin to feel the affects again.

Even at this time of the year though you can see that there is thinning and variation

Answer 2

First we need to realise that there was an Ozone hole before there were CFC's. Ozone is formed in all of the upper atmosphere where there is enough light and it is warm enough, it also constantly oxidises any substance that it can react with, including CFC's if they reach high enough. Over most parts of the world the rate of production of ozone is ahead of it's destruction. In winter over Antarctica the tilt of the earths axis is such that there is little light, less than over the Arctic in the Northern winter. It can also be very cold. As a result little ozone forms over the Antarctic in some winters. In spring and early summer this is described as a hole in the ozone layer. Exactly why CFC's were singled out is unclear but limiting their release seemed to be reducing the size of the hole until this year. However it was very cold over the Antarctic this winter so that would be enough to explain the discrepancy. As global warming increases the temperature of the upper atmosphere the hole should close for good.

Answer 3

The CFC have nothing to do with it. The ozone holes are natural and caused by the solar winds colliding with the magnetic . The ionized particles from the sun breaks into 2 parts. The beta particles are attracted to the north pole and the alfa particles are attracted to the south pole. The north pole is charged negative. The south pole is charged positive. This supplies a battery like charge that ionizes the Van Allan belt. As the tilt of the earth become more toward the sun the particle beams blow a hole in the ozone layer at the poles so it will not hurt anything.

Answer 4

Due 2 the rotation and revolution of the earth the concentration of the gas becomes maximum at the poles,like:when we churn butter milk the butter gets collected in the centre due to the centrifugal force.The same example applies for the above method.Hence the ozonelayer is only depleted over ANTARTICA and not other places where there is 2 many release of CFC's.
