The ozone depletion is greatest at the poles. It is due to the cold temperatures there.
The greatest natural cause of ozone depletion is UV rays. But they also replenish it.
The CFC's have greatest effect. They react with ozone to deplete it.
Ozone depletion is not worse in cities. If you measure the effects of ozone depletion by the number of people affected, there are more people per unit area in cities. Ozone depletion affects every unit area more-or-less equally. Ozone pollution affects cities worst, since NOx is mostly produced by urban and suburban<->urban traffic.
Ozone depletion occurs in the ozone layer.
The release of chlorofluorocarbons (CFCs) and other ozone-depleting substances, primarily used in refrigeration, air conditioning, and aerosol sprays, has had the greatest effect on ozone depletion. Once in the atmosphere, these chemicals break down ozone molecules, leading to the thinning of the ozone layer.
Ozone depletion is the depletion of ozone molecules. It is happening because of CFC's.
The major cause of ozone depletion is the reaction of CFC with ozone. They decompose ozone and cause its depletion.
Depletion layer The area in a P-N junction that is free of (i.e., depleted of) current carriers.
Ozone depletion refers to the depletion of ozone molecules. These molecules are present in the ozone layer.
The solution for ozone depletion is curbing CFC's. They could prevent ozone depletion.
The atmosphere does not protect the ozone depletion. It is the region where the ozone depletion occurs.
Ozone depletion is the thinning of ozone layer below a certain concentration. This phenomenon is termed as ozone depletion.
