The ozone in the ozone layer is said to be depleting the most at the poles itself.Though there is no population there and no industries but still the max depletion is said to be there. It is because of a no. of reasons:
1) The CFC's which are released over the regions of the mid latitudes are carried by the westerlies or the westerly winds which flow from the equator to the poles. On their way they carry most of the CFC'r which come their way and thus making them active only at the poles.
2) The temperature required for the depletion of ozone is very low. Actually the phenomenon of the ozone depletion is carried on the polar stratospheric clouds or PSC's which exist only at very low temperatures. These polar stratospheric clouds act as a base for all the ozone depleting reactions. And the temperature required for the formation of these PSC's is only acquired at the poles thus making the place suitable for the depletion of ozone.
Thus these factors re the ones that contribute towards the formation of ozone hole on the poles.
Ozone is disappearing. It is because of the increasing CFC's.
Scientists believe that the ozone layer is disappearing because there is a large hole in it. This hole was not there years ago.
the ozone layer is basically..disappearing. this is happening because of pollution in our atmosphere.
Ozone is disappearing. It allows harmful UV to come through.
Yes, the ozone layer is not disappearing, but it has been depleted in certain areas due to the release of harmful chemicals like chlorofluorocarbons (CFCs). Efforts have been made to reduce these emissions and protect the ozone layer.
They think ozone is disappearing. It is because of increased UV radiations.
The ozone layer is disappearing from Antarctic. It is because of the westerly winds that carry CFC's.
Ozone layer is disappearing. I is because of the increased UV content on earth.
Ozone layer is disappearing because CFC gases which are pollutants are responsible for the depletion of ozone layer. CFC convert ozone to oxygen and make it useless for the absorption of UV radiation.
By considering the concentrations of ozone in the recent times it can be surely said that the ozone is disappearing from the ozone layer present in the stratospheric region of the atmosphere. This disappearing of ozone is the main cause of the phenomenon of ozone hole. this ozone hole is nowadays becoming a serious worry on the foreheads of the modern scientists as this ozone hole could allow the harmful ultraviolet radiations to reach the surface of earth and cause harmful problems to the human race which include the skin cancer, suppression of immune system, eye cataract etc.
In order to prevent depletion, ban the use of CFC's. You can use HCFC's.
Ozone disappearing is a problem as it allows UV rays to allow enter the earth. They are fatal for life on earth.
