Question

The maximum hole of ozone is found over
a. Arctic zone
b. Antarctic zone
c. Tropical zone
d. Subtropical zone

Answer 1

Hint: Ozone-depleting substances square measure gifts throughout the stratospheric ozonosphere as a result of they're transported nice distances by region air motions.

Complete answer:
Let us analyze the given options and find the correct solution:
a. In the regions to the north of the polar circle focused on the North Pole. Synonyms: the Arctic, North polar zone Example of the polar zone, polar region, polar zone. a part of the Earth's surface, characterized by a frigid climate, forming a cap over a pole.

b. The severe depletion of the Antarctic ozonosphere referred to as the “ozone hole” happens as a result of the special region and chemical conditions that exist there and obscurity elsewhere in the world. The drastic low winter temperatures within the Antarctic layer cause polar stratospheric clouds (PSCs) to form unique reactions that befall on PSCs, joined with the relative isolation of polar stratospheric air, enable Cl and element reactions to supply the hole in Antarctic season.

c. The tropics are regions of the planet that lie roughly within the middle of the world. The tropics between the latitude lines of the Tropic of Cancer and also the Tropic of Capricorn. The tropics embody the Equator and components of North America, South America, Africa, Asia, and Australia.

d. The climatic zone square measure geographic and climate zones set roughly finite the tropics at latitude 23° 27' and also the temperate zones, north, and south of the Equator. climatic zone climates square measure typically characterized by hot summers and delicate winters with rare frost.

Hence option: b is the correct answer.

Note: The Antarctic hole is currently on its thanks to recovery — last year's hole was the tiniest on record — however, it'll take decades for the chemicals to utterly disappear.
