Question

Eventhrough, pollution occurs on continents like europe, asia, africa, australia then why ozone depletion is major in the antarctic circle?? ​

Answer 1

Answer:

Antarctic winters are very cold. The very low stratospheric temperatures lead to the formation of clouds (polar stratospheric clouds) that are responsible for chemical changes that promote production of chemically active chlorine and bromine. This chlorine and bromine activation then leads to rapid ozone loss when sunlight returns to Antarctica in September and October of each year, which then results in the Antarctic ozone hole.
