Formation of the ozone hole is maximum over
(1) Africa
(2) India
(3) Antarctica
(4) Europe
Answer: (3) A continent-sized hole (thinning) has been formed over Antarctica as a result of damage to the ozone. Most ozone is formed in the stratosphere over the equation and spread by winds around the globe. Icy particles in polar stratospheric clouds catalyze the release of chlorine (from CFC) which destroys ozone. The thinning of ozone is maximum because winter there is exceptionally cold.
