Ozone needs constant sunlight to replenish itself, especially now when it is being destroyed by CFCs which will remain in the atmosphere for at least another 50 years, even after we stop releasing them.
The North and South Poles have six months of darkness, so during that time no ozone is produced. The South Pole is much colder than the North Pole and the frozen clouds also help to release the chlorine from the CFCs. This is why the ozone hole is largest at the South Pole, the Antarctic.
The ozone at poles is damaged. It is due to cold temperature there.
The ozone layer is damaged primarily over Antarctica and the Arctic regions. This damage is known as the ozone hole, caused by the release of chlorofluorocarbons (CFCs) into the atmosphere. Efforts have been made to reduce the use of CFCs in order to allow the ozone layer to recover.
The thinnest layer of ozone is at the poles. It is because the depletion is abundant at the poles.
The ozone layer is damaged by the CFC's and the halogens. There halogens affect the ozone by reacting with it.
Ozone layer is a complete layer. Only the ozone at the poles is destroyed.
Depletion of ozone layer is near the poles. It is actually at the poles. It is because of low weather.
The big hole(whole) in the ozone layer is over poles. The poles carry these holes.
The ozone layer is damaged over the poles. It is due to the low temperature.
Yes, the ozone layer is being damaged by the humans. CFC's are main reason for depletion of ozone layer.
Ozone layer depletion is the thinning of ozone layer. It is most evident over the poles on earth.
The hole in the ozone layer happen to be closer to the poles. It is because the ozone depletion occurs in very low temperatures which can only be obtained at the poles.
The ozone layer at poles is depleting. It is because of cold degrees of temperature there.
