Question

Ozone whole depletion is only over antartica and not other places? Well why, or actually how?
i was unable to understand the answer by watching the video.....somehow....

Answer 1

chemicals (e.g. chlorofluorocarbons (CFCs)). When CFCs are hit by ultraviolet light, they release chlorine. Chlorine reacts with ozone, destroying it to produce chlorine monoxide and diatomic oxygen.

These reactions are most effective when they occur on the surface of ice crystals, in the stratosphere. There are more ice crystals when it is most cold.

Antarctica is colder than the Arctic circle because the ratio of land to water is higher.

Therefore ozone depletion over the South Pole is greater than ozone depletion over the North Pole.the unique weather phenomenon. As Robert mentioned that the temperatures drop pretty low due to the land water ratio.The ozone hole is caused by the effect of pollutants in the atmosphere destroying stratospheric ozone. During the Antarctic winter something special happens to the Antarctic weather.

First, strong winds blowing around the continent form, this is known as the "polar vortex" - this isolates the air over Antarctica from the rest of the world.
