Ozone formation is a natural process. It is a chemical process. When oxygen is treated with UV radiations oxygen gets converted into ozone.
The formation of the ozone layer
The formation of the ozone layer
The formation of depletion layer of ozone is due to human made ODS. They react with the ozone layer and then deplete it.
UV rays formed the ozone layer. They also destroyed the ozone.
See "How did the ozone hole occur?"
Ozone depletion is the formation of holes in ozone layer, It is caused by CFC gases.
Ozone has nothing to contribute in cloud formation. It is all done in the troposphere 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.
Troposphere
Ozone production occours in stratosphere. It is present as ozone layer.
Thinning of ozone layer occurs due to UV. UV is fatal for life also.
