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.
What else can I help you with?
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.
What polar regions contains more land?

Are the locations of the magnetic South Pole and the geographic North Pole near Antarctica or the Arctic?
Anything north is Arctic, anything south is Antarctic.
Do penguins live in the North Pole or arctic region?
Penguins do not live in the North Pole or the Arctic region. They are native to the Southern Hemisphere, predominantly found in Antarctica, with some species also inhabiting areas in Australia, South America, and Africa.
What continents does the arctic tundra belong in?
The Arctic Tundra is present in North America, Europe, and Asia. The Arctic Tundra is a type of tundra present around the Arctic Ocean's coastline.
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.
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.
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 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.
What polar regions contains more land?
it is Antarctica
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. Antarctica is a continent of approximately 14,000,000 sq km. The Arctic is a floating ice sheet.
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.
