Ozone reaction happen only i sunlight. Like ozone depletion takes place in PSC's.
Photochemical Smog is any chemical reaction that takes place with the presence of sunlight. The most common example is Ground-level Ozone, caused by reactions of common pollutants along with their reaction to the sunlight.

No. The ozone layer is unaffected by storms that happen "miles" below it. The ozone hole closes when sunlight with UV-C finally makes it to that region of the atmosphere and ozone is made, rather than diffusing in from regions that do get UV-C.
Nitrogen oxide is formed after reaction with ozone. It is also an ozone depleting substance.
Because Earth's axis is tilted, once a year, each pole spends some long time without sunlight. Ozone decays with time, so the only ozone found there must diffuse in from areas that *do* get sunlight, that *do* make ozone with that sunlight.
Ozone protects us from harmful part of sunlight. It protects from the harmful UV rays of the sun.
The layer is heated. Some oxygen, nitrogen, and ozone molecules are destroyed. Ozone is made. This is how the ozone layer returns after the polar winters deplete the layer. Lack of sunlight is the major issue with ozone depletion and the ONLY method that allows the ozone to return.
The ozone is naturally create. Sunlight and thunder help in its formation.
CFC's are a source of ozone depletion. It is due to their reaction with ozone.
CFC's react with ozone. They deplete the ozone layer.
The main reason behind ozone hole is the reaction of the chlorine molecules from CFC's. These molecules initiate a chain reaction which then destroy the ozone molecules to form the ozone hole.
