Question

Formation of ozone hole is maximum over

(a) Europe

(b) Africa

(c) India

(d) Antarctica.

Answer 1

Formation of ozone hole is maximum over (d) Antarctica due to it's lower temperature, formation of antarctic polar vortex and formation of polar stratospheric clouds.

Lower temperature: lower temperature leads to the formation of ice particles. These ice particle can trap some ozone depleting molecules life CFC. It also responsible for polar stratospheric clouds.

Antarctic polar vortex: this can lead to the separation of the air on antarctic from the rest of the earth. So the depleted stratospheric ozone layer can not be healed by the ozone residing to the another part of the stratosphere of the earth. It isolates the air on antarctic from rest of the air of earth's environment.

Polar stratospheric clouds: these can store gases that can lead to depletion of ozone.
