Question

i have a small doubt.......... antarctica is a cold place with very less people living but the rest of the world has billions of people living. now my question is that even if nobody is living in antarctica then also why the ozone layer has a hole over antarctica and not over any other place . please donot ignore my question.

Answer 1

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. Special reactions that occur on PSCs, combined with the relative isolation of polar stratospheric air, allow chlorine and bromine reactions to produce the ozone hole in Antarctic springtime. The term “ozone hole” came about as a description of the very low total ozone values that encircled the Antarctic continent in satellite images for many weeks .Currently, the formation and severity of the Antarctic ozone hole are documented each year by a combination of satellite, ground-based, and balloon observations of ozone.
so it is not in any way related to the population of that place. IT is not always as a result of human activities.
