Because the Ozone in the upper atmosphere is created by Ultraviolet (UV-C) light hitting Oxygen molecules in the air and the intensity of incident light is higher near the the equator as compared to the poles. The poles receive *no significant*UV-C when it is winter at that pole. Additionally, Earth's magnetic field redirects electrons from the solar wind to the North pole, while the positive charges are directed to the South pole. The positive charges are largely protons, which become hydrogen in our atmosphere. Hydrogen oxidizes to water vapor, and water vapor both blocks one path of ozone formation (via N2O* as a temporary placeholder for an oxygen atom), and accelerates the decay of ozone (via formation of H2O2). This explains why the south polar hole is much larger than the north polar hole.

∙ 12y agoCFCs and related halocarbon gases are the main cause of ozone depletion all over the world. CFCs released from Western countries take several years to reach the stratosphere where the ozone layer is. During that time winds spread them all over the world. In the presence of ultraviolet light these gases release chlorine and bromine atoms which destroy some of the ozone in the ozone layer. This is called ozone depletion. The ozone hole is a related but different phenomenon.
The hole is Antarctica occurs in the spring (September to December). It begins with this overall ozone thinning, but it is assisted by the presence of polar stratospheric clouds (PS clouds). During the extreme cold of winter, with no sun for six months, polar winds create a vortex which traps and chills the air; the temperature is below -80 Celsius. The ice in these PS clouds provides surfaces for the chemical reactions that destroy the ozone. This needs light to kick-start the reactions.
In spring the sun rises above the horizon and provides energy which starts the photochemical reactions. The clouds melt and the trapped compounds are released. Ozone in the lower stratosphere is destroyed and the ozone hole appears.
By the end of spring warmer December temperatures break up the vortex, destroy the PS clouds and sunlight begins creating ozone again and the hole begins to repair.
(A similar hole in the Arctic [but smaller because of warmer temperatures] occurs during spring.)
A:The use of chlorofluorocarbon gases such as freon had the unexpected side-effect of catalysing the dissociation of ozone molecules in the upper atmosphere. This happens faster in the cold region over the poles because ice particles contribute to this process.See the related questions section below.

∙ 12y agoThere is a smaller ozone hole at the North Pole, but the hole in Antarctica is largest because the South Pole is much colder than the North Pole (-80 C).
Wiki User
∙ 13y agoBecause it is in the middle of a continent and at a high elevation. While the North Pole is in the middle of an ocean which keeps temperatures higher.

∙ 9y agoThe ozone hole is formed over south pole. It is because of the CFC's that are carried by westerly winds.

∙ 8y agoOzone hole depletion is more towards the poles. It is because ozone depletion is abundant in cold areas.

∙ 8y agoThe ozone depletion is more severe over the south pole.It was because of the CFC's carried to south pole by westerlies.

Where is the biggest hole in the earths ozone layer?
Ozone layer is depletion is happening in the stratosphere of the earth's atmosphere. It is majorly concentrated over Antarctica's atmosphere.
Is there a hole at the North Pole?
Not a hole, but there was a large ozone layer hole right above the South Pole. That ozone hole has diminished in size in the last few years, effectively "healing".
Where are all of the ozone holes located?
There are many holes in the ozone layer, the largest is above the south pole.
Where is the large hole in the ozone layer found?
The largest hole in our ozone layer is over the South Pole, over Antarctica.
Where is the hole in the ozone found?
Ozone layer is depletion is happening in the stratosphere of the earth's atmosphere. It is majorly concentrated over Antarctica's atmosphere.
Why is the hole of the ozone layer at the south but the north uses gas?
The ozone hole is south. It is because of the westerlies that carry CFC's.
How South Africa is restoring ozone layer?
South Africa is restoring the ozone layer by banning CFC's. They have stopped its use.
Is the ozone layer opening?
No at the moment. The ozone hole at the south pole has formed and is closing. The hole at the north pole probably has not started forming yet.
How big will the ozone layer get?
The ozone layer is largest when it is spring / fall at both poles. It is smallest when it is winter at the South pole.
How ozone layer recover in summer in south poles?
Ozone layer forms in summer. therefore it initiates its recovery at that time.
Which state of Australia is most likely to be affected by the ozone layer?
The state of South Australia is the place in Australia most likely to be affected by the ozone layer. This is because of the hole in the ozone layer.
Where is the biggest hole in the earths ozone layer?
Ozone layer is depletion is happening in the stratosphere of the earth's atmosphere. It is majorly concentrated over Antarctica's atmosphere.
Why and where is the hole in the ozone layer?
The hole in ozone is over the south pole. Antarctica has the largest.
Is there a hole at the North Pole?
Not a hole, but there was a large ozone layer hole right above the South Pole. That ozone hole has diminished in size in the last few years, effectively "healing".
Is there any hole in the ozone layer now currently?
The ozone hole is in the south pole. It is over Antarctica.
Where are all of the ozone holes located?
There are many holes in the ozone layer, the largest is above the south pole.
Which hemesphere is the hole in the ozone layer?
The hole is in the southern Hemisphere. It is at the south pole.
