Why is the ozone layer hole formation less severe in arctic region compare to Antarctica?

The Antarctic hole is larger than the Arctic because the South Pole is far colder (-80 C) than the North. Cold conditions allow more chlorine and other radicals to destroy the ozone.
Ozone is a protective layer in the upper atmosphere. It is formed, when oxygen molecules absorb short wavelength ultra violet radiations from the sun. Ozone is mostly destroyed by free radicals in the atmosphere.
When compounds like CFCs (chlorofluorocarbons) and other halocarbons are released, they are dissociated by sunlight into chloride radicals. These radicals attack ozone, thereby decreasing its concentration. This results in a thinning of the ozone layer, and in polar regions, a hole.
The holes occur at the poles, and usually in Antarctica because of the extreme cold. During the winter polar stratospheric clouds form which are able to convert gases in the atmosphere into Cl (chlorine) and ClO (chlorine monoxide). When the sun arrives at the end of winter, that is the trigger to begin. This is why the hole is largest in spring.

Is the north pole in the arctic region or antarctic region?
You are in the arctic region.The pole in Antarctica is called the south pole.
Is the arctic or Antarctic region in the north pole?
The North Pole is in the Arctic Region.
What island is in the Arctic region but belongs to a country outside the Arctic region?
greenland
What is Antarctica made up of besides ice?
AnswerUnlike the arctic region in the north, Antarctica is a continent. It is land, and there are actually some exposed sections of the land. Most of the continent is covered by thick ice sheets. Any ice in the Arctic region is floating on water.
Is the North Pole in the Arctic or Antarctic region?
The North Pole is located in the Arctic, the South Pole is located in the Antarctic. The region around the North Pole is known as the Arctic.
Is it the Arctic or the Antarctic region that is solid ice?
The arctic is is mostly ice. Antarctica is a continent that is included in the antarctic region.
Is the north pole in the arctic region or antarctic region?
You are in the arctic region.The pole in Antarctica is called the south pole.
Does Antarctica have polar bears?
No, they are animals of the Arctic region only.
What does the word antarctica mean?
The word Antarctica means "opposite of the Arctic." It is derived from the Greek words "anti" (opposite) and "arktos" (bear), referring to the Arctic region. Antarctica is located in the Southern Hemisphere, making it the opposite of the Arctic region in the Northern Hemisphere.
What region does Antarctica associate with?
India, Africa, Australia, and South America.
Does north Antarctica have polar bears?
No, they are animals of the Arctic region only.
Which continent has more land the Arctic or Antarctica?
Antarctica has more land than the Arctic. Antarctica is a continent surrounded by the Antarctic Circle, while the Arctic is a region surrounded by the Arctic Circle and consists of mainly ice-covered ocean with some landmasses.
Which one of these is not a continent Europe the arctic or antarctica?
The Arctic is not a continent. It is a polar region located around the North Pole. Europe and Antarctica are both continents.
Are polar bears native to Antarctica?
No, there are no Polar Bears on Antarctica. Polars Bears are indigenous to the Arctic region of the Northern Hemisphere.No.
Are both the Arctic and Antarctica continents?
No, only Antarctica is considered a continent. The Arctic is an ocean region covered by sea ice and surrounded by North America, Europe, and Asia.
Which Polar region has more land?
The Antarctic region has more land than the Arctic region. Antarctica is a large continent comprised mostly of land covered in ice, while the Arctic is mostly comprised of water surrounded by land masses.
Why is the Antarctica the coldest region?
Antarctica is one of two polar regions on earth. Because the landmass there, which covers about 10% of the earth's surface, it is called a heat-sink, and is generally about 30 degrees colder than the other polar region, the Arctic. There is no landmass in the Arctic.
