Why holes in ozone layer are formed only above the poles and not in other areas?

Answer 1

Holes are formed only over poles because of temperature. It requires cold temperature.

Answer 2

Ozone holes form predominantly above the poles due to specific conditions in the stratosphere during polar winter. These conditions lead to the release of chemicals, like chlorofluorocarbons (CFCs), that break down ozone. The polar environment allows for the accumulation of these ozone-depleting substances, resulting in the formation of ozone holes.
