Why did the Ozone hole form only above the poles , and not anywhere else ?

Answer 1

The reactions involving CFC's that destroy ozone only occur at temperatures lower than -180 below F. The only place on earth where the temps get this cold are over the polar areas. Ozone holes have nothing to do with CO2

Answer 2

Ozone is created by ultra violet light waves striking oxygen molecules causing them to split and making free atoms of oxygen available to bond with other molecules. SInce the amount of sunlight striking at the poles is far less than that striking the equator the greatest concentration of ozone production will be at the equator.

The earth spins rapidly. Angular momentum forces ozone above the poles to migrate towards the equatoral regions further thinning it above the poles.

There is a lot we don't understand about the ozone layer and its mechanics. How it works is in large part a mystery but we do know volcanic action and solar winds have a huge impact on it. Most of the rest of what you hear is theory at best and pop science at worst. If you watch the news closely you'll see a lot of contradictory information about the ozone layer and its status.

Answer 3

OZZONE is nothing but O2 so when CFC's are released{Chloro Floro Carbon} that harms the OZONE layer due to movement of the earth it gets moved towards the poles and it react with the OZONE layer and the HOLES are formed in Ozone layer at poles

Answer 4

That's where the CO2 tends to go.
