Question

Why there is ozone depletion mainly over Antarctica?

Hello Friend .............

Here is your answer...........

The severe depletion of the Antarctic ozone layer known as the “ozone hole” occurs because of the special atmospheric and chemical conditions that exist there and nowhere else on the globe. The very low winter temperatures in the Antarctic stratosphere cause polar stratospheric clouds (PSCs) to form.

Ozone layer depletion mainly occurs in Antarctica because Antarctica has very low temperature. In addition to this the chemicals and atmospheric condition that exists there is not found anywhere else in the world.
