The main ozone hole is not over Arctic. It is because westerly carry CFC's over to the other pole.
The Arctic ozone hole is a region of exceptionally depleted ozone in the stratosphere over the Arctic region. This depletion is caused by the presence of certain chemicals, such as chlorofluorocarbons (CFCs) and other ozone-depleting substances. The Arctic ozone hole forms during the winter and spring months when polar stratospheric clouds enable chemical reactions that break down ozone molecules.
The second hole was found over Arctic. Opposite to that of the 1st hole.
The main ozone hole is located over Antarctica. It forms in the southern hemisphere during the Southern Hemisphere spring (September to November) due to the presence of man-made chemicals like chlorofluorocarbons (CFCs) and halons which break down ozone molecules.
Currently (2009dec23), there is no hole in the ozone layer at either pole. The maximum ozone hole size occurred in 2006. So it appears it is no longer growing.See "How did the ozone hole occur?" in the "Related questions" section below.
The hole in the ozone layer is located over the poles that is Antarctica and arctic. It is because the process of ozone depletion requires very low temperatures to initiate and that temperature is only available at the poles.

Ozone hole is mainly located over Antarctica. It is also over Australia and Arctic.
The 2nd hole was found over Arctic. It was opposite to the 1st hole and smaller.
The second hole was found over Arctic. Opposite to that of the 1st hole.
The ozone hole is mainly found over the region or antarctica and arctic because of the temperature. Ozone depletion requires very less temperature which can only be found at the poles.
Ozone hole is created over low temperatures. It is because ozone hole is over Antarctica.
The main ozone hole is located over Antarctica. It forms in the southern hemisphere during the Southern Hemisphere spring (September to November) due to the presence of man-made chemicals like chlorofluorocarbons (CFCs) and halons which break down ozone molecules.
Ozone hole was discovered by Joseph Farman. He discovered the ozone hole over Antarctica.
No the ozone hole is not constant over the time
The main impact is on poles. The ozone hole is over Antarctica.
Currently (2009dec23), there is no hole in the ozone layer at either pole. The maximum ozone hole size occurred in 2006. So it appears it is no longer growing.See "How did the ozone hole occur?" in the "Related questions" section below.
Antarctic ozone hole is the ozone hole over Antarctic. It is due to cold weather there.
