The thinning of the Southern Hemisphere's ozone layer that occurs each year is due to a lack of sunlight hitting this region. The worst "hole" that we know of occurred in 1838 due to high solar activity. There are some groups that believe that cfc's are reaching this layer and causing some issues. The problems with this concept is the levels of cfc's in the atmosphere and the location and reason for the thinning of the layer.
The group of gases that are known to degrade ozone *when sunlight strikes them*, are molecules that contain chlorine or bromine. Sunlight (less energetic than UV-B) breaks off the chlorine or bromine, they end up creating an ozone decay path, and the sunlight reactivates them.
Water vapor alone, without sunlight, will destroy ozone, and reset spontaneously to destroy ozone.
So the only "group" that contains both is "ozone depleting substances".
Water vapor, any gas with a carbon-carbon double bond, and any gas with a less-than-fully-oxidized sulfur. Additionally, there are other compounds that can accept the extra oxygen for some period of time, but are otherwise unaffected when the interchange is complete (catalytic decay). CFCs are an example of the latter.
Mainly Chloroflurorocarbons (CFC's)
See the related questions section below.
The main gases causing ozone layer depletion are:
It's a small group of gasses (all of them similar) that are collectively called "chlorofluorocarbons". Mostly, they were used as refrigerants.
Manmade chemicals like chlorofluorocarbons, bromofluorocarbons and water vapor the major depleters of the ozone layer.
Chlorofluorocarbons used to be destroying the ozone layer and creating an ozone hole (until it was banned).
CFC's destroy ozone. They react with ozone to deplete it.
Greenhouse gases are destroying the ozone layer. They also cause greenhouse effect.
Greenhouse gases are the ones. They react with ozone to deplete it.
The CFC's destroy ozone layer. These are synthetic gases of earth. They are manufactured as refrigerants.
CFC's are responsible. they react with ozone and deplete it.
No, they are not. CFC's destroy the ozone layer.
Popping bubble wrap does not destroy ozone.
Ozone gas present in the stratospheric region of our atmosphere in the form of ozone layer is the one most prominent gas which is responsible for the absorption of the harmul UV radiations coming from the sun.
The ozone depleting substances are interfering with ozone. They destroy the ozone.
Popping bubble wrap does not destroy ozone.
See "What is causing the depletion of the ozone layer?"
CFCs (chlorofluorocarbons) destroy ozone in the ozone layer.
Yes, CFCs can destroy the ozone layer. They react with ozone present in ozone layer and decompose it.
Yes.CFC's destroy the ozone layer.
You don't destroy ozone layer. It is vital for life on earth.
No, it does not destroy. The ozone layer is present in stratosphere. No meteor shower can destroy it.
The chemicals that destroy the ozone layer are CFC's. These CFC's are cholorofluorocarbons which react with ozone to destroy it.
Ozone layer is formed of ozone. It is a gas.
CFC's destroy ozone. They react with ozone and deplete it.
Stratosphere contains the ozone gas. It is present as the ozone layer.
HCFC do not destroy ozone. They are an alternative to CFC's.
The ozone layer can be destroyed by CFC's. They react with ozone.
