The natural processes that cause an ozone hole are (in rough order): # time and temperature (ozone is unstable, and decays back to oxygen) # water vapor (works without applied UV, as it adds a decay path for ozone) #2 is why the Antarctic ozone hole is larger than the Arctic ozone hole. Earth's magnetic field is currently aligned to direct positive ions of the solar wind to the south pole. Most of these are hydrogen nucelii, which oxidize (eventually) to water vapor.
Ozone layer is caused by natural processes. It is formed by UV.
Ozone layer is created by natural processes. UV and thunder are some of them.
The thinning of ozone layer is the depletion of ozone molecules. It is caused by various man made and natural processes.
The hole in the ozone layer is the falling of the concentration of the ozone layer below a certain concentration. It is caused by various man made and natural processes.
Ozone holes are the thinning of ozone molecules. This is caused by man made or natural processes.
The ozone is a natural cycle. It is because various factors that cause ozone depletion also replenish it.
Chlorofluorocarbon (CFC) gases used in refrigeration
No it is not. It is caused by man made CFC's.
Ozone hole is created by natural and man made processes. Man made are CFC's.
Yes it does. Chlorine depletes the ozone layer.
See "What is the depletion of the ozone layer?" in the "Related questions" section below.
The man made chemicals, CFCs or chlorofluorocarbons are influence on the Ozone layer. CFCs are use in aerosol propellants, refrigerants, foams, and industrial processes.
