Because Earth's axis is tilted, once a year, each pole spends some long time without sunlight. Ozone decays with time, so the only ozone found there must diffuse in from areas that *do* get sunlight, that *do* make ozone with that sunlight.
The ozone hole is near the poles. It is because of the low temperatures there.
The greenhouse effect the ozone at the poles. It is the maximum at the poles.
The thinnest layer of ozone is at the poles. It is because the depletion is abundant at the poles.
The ozone hole is present over the poles. It is the thinning of the ozone layer.
Poles is the worst area for ozone depletion. It is because of the low temperatures there.
Ozone layer is thin over Australia. It is due to its location near poles.
The ozone hole is near the poles. It is because of the low temperatures there.
The ozone is problematic in poles. The poles are the one that have maximum depleted.
The ozone is depleted at the poles only. It is because of the low temperature there.
The greenhouse effect the ozone at the poles. It is the maximum at the poles.
The thinnest layer of ozone is at the poles. It is because the depletion is abundant at the poles.
The snow on poles is not responsible for ozone depletion. There is no connection.
The ozone layer at poles is depleting. It is because of cold degrees of temperature there.
Depletion of ozone layer is near the poles. It is actually at the poles. It is because of low weather.
The ozone depletion is mostly over poles. It is due to the low temperature at the poles.
All over but it is specially noticeable over the poles, and more over Antarctica, which is colder than the North Pole.
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.
