UV rays formed the ozone layer. They also destroyed the ozone.
No. The ozone layer has no effect on the formation of smog.
The formation of depletion layer of ozone is due to human made ODS. They react with the ozone layer and then deplete it.
Ozone has nothing to contribute in cloud formation. It is all done in the troposphere layer.
Ozone depletion is the formation of holes in ozone layer, It is caused by CFC gases.
The formation of the ozone layer
Ozone layer absorbs the UV rays of the sun. They are fatal for life on earth.
The ozone layer forms in the stratosphere by UV rays. The stratosphere is the ideal location for its formation.
Ozone formation is a natural process. It is a chemical process. When oxygen is treated with UV radiations oxygen gets converted into ozone.
Troposphere
CFCs, or chlorofluorocarbons.
Ozone is a very unstable molecule. The energy required of formation of ozone is much greater than the reverse process that is the formation of oxygen and nascent oxygen. However there is an ongoing process of formation as well as depletion in the ozone layer which makes its concentration in the ozone layer constant. However due to the CFC's the rate of depletion is increasing thus creating an ozone hole in the ozone layer.
The use of CFC contributed to depletion of ozone. It is because they react with ozone to decompose it.
