Why are the holes in the Ozone WHERE they are (over Antarctica & not over America/other heavy pollution areas)

Answer 1

The spinning effect of the earth.


xxB

Answer 2

The S pole and Ozone hole are associated because the conditions are correct there to form a yearly ozone hole at the end of the Antarctic winter. Ozone destruction does occur in other places but mostly in Antarctica by the method briefly described below.
During the winter months there is a wind pattern called the polar vortex and this prevents most of the air over Antarctica mixing with the rest of the world. Also during winter, when there is no sunlight, ice crystals build up in clouds high above Antarctica. When the sunlight hits them in spring (October in Antarctica) ozone destroying chemical reactions occur with CFCs (also trapped in the polar vortex since they are spread throughout the atmosphere). The polar vortex also breaks down and the 'hole' (or air with less ozone) is mixed around the world.

Answer 3

Because the holes are not caused by pollution. They are a result of the paucity of UVA & UVB radiation at those latitudes. (the surface area presented to the Sun is sometimes 0, depending on latitude & season)

Answer 4

its to do with the ice i think but i'm not sure. anyway nw europe and ne america do have ozone depletion. But the holes i think are diminshing due to less cfc use.

Answer 5

Seattle and Texas. George Bush's head sticks out of one and Al Gore's sticks out of the other.

Answer 6

they are the most effected by the solar radiation as the earth's magnetic field has its poles there.

Answer 7

there are no more holes, they are repaired because we use no more CFC's or that is what people want you to belive, they might just have reparied them self

Answer 8

All to do with rotation and gravity....
