UV rays formed the ozone layer. They also destroyed the ozone.
The formation of depletion layer of ozone is due to human made ODS. They react with the ozone layer and then deplete it.
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.
The formation of the ozone layer
Ozone layer absorbs the UV rays of the sun. They are fatal for life on earth.
The production of CFCs in Canada has contributed to ozone layer depletion globally, not just in Canada. CFCs break down ozone molecules in the stratosphere, leading to the formation of the ozone hole. Canada's efforts to phase out CFCs through international agreements like the Montreal Protocol have helped mitigate the damage to the ozone layer.
The ozone layer forms in the stratosphere by UV rays. The stratosphere is the ideal location for its formation.
CFCs, or chlorofluorocarbons.
Ozone formation is a natural process. It is a chemical process. When oxygen is treated with UV radiations oxygen gets converted into ozone.
The use of CFC contributed to depletion of ozone. It is because they react with ozone to decompose it.
Troposphere
Ozone layer and it's depletion is pure chemistry. It's formation and depletion is due to the chemical bonds.
