Chlorofluorocarbons (CFCs) deplete the ozone layer because when they are released into the atmosphere, they break down and release chlorine atoms. These chlorine atoms then react with ozone molecules in the stratosphere, causing the ozone molecules to break apart, leading to ozone depletion.

How do chlorofluorocarbons build up in the atmosphere?
Chlorofluorocarbons (CFCs) build up in the atmosphere when they are released from products like refrigerants and aerosols. Once in the atmosphere, CFCs break down and release chlorine atoms, which then catalyze the destruction of ozone molecules in the ozone layer.
Is destroyed by chlorine atoms released from CFCs?
Chlorofluorocarbon i.e. CFC's are the compounds released from refrigrants and air conditioners. These being lighter than the air are carried upwards towards the atmosphere, stratosphere to be precise. These CFC's there in the presence of high energy ultraviolet rays breakdown into chlorine and fluorine which further react with ozone to form unstable compound and deplete it.
What is water vapor and CFC's used in?
Water vapor is naturally present in the Earth's atmosphere and plays a key role in the water cycle. CFCs (chlorofluorocarbons) are used in refrigeration, air conditioning, and aerosol propellants. However, CFCs have been found to deplete the ozone layer in the stratosphere, leading to the implementation of regulations to phase them out.
What is the gas in old fridges?
Old fridges typically use chlorofluorocarbons (CFCs) as the refrigerant gas. These gases have been phased out due to their harmful effects on the ozone layer.
What is the chemical chlorofluorocarbons supposed to do?
CFCs (or chloroflurorocarbons), were used in aerosols or as coolants for refrigerators. They are extremely inert, which made them very useful, however, when exposed to UV light, they formed free radicals that reacted with ozone, thereby creating the phenomenon that resulting in a hole in the ozone layer above Antartica. As a result, CFCs were banned by nations after the signing of the Montreal Protocol.
What affects does chlorofluorocarbons have had on your ozone layer?
CFCs are the chemicals that are responsible for the depletion of ozone layer. These chemicals react with ozone to deplete it.
How do chlorofluorocarbons damage ozone?
See "What is causing the depletion of the ozone layer?"
Which compound is most likely responsible for the depletion of the ozone layer?
Chlorofluorocarbons (CFCs) are primarily responsible for the depletion of the ozone layer. When CFCs are released into the atmosphere, they break down ozone molecules, reducing the ozone layer's ability to protect the Earth from harmful UV radiation.
What can destroy the ozone?
CFCs (chlorofluorocarbons) destroy ozone in the ozone layer.
Do chlorofluorocarbons have a negative effect on the ozone layer?
Yes, chlorofluorocarbons (CFCs) have a negative effect on the ozone layer. When CFCs are released into the atmosphere, they break down and release chlorine, which can destroy ozone molecules. This depletion of the ozone layer can result in increased levels of ultraviolet (UV) radiation reaching the Earth's surface, leading to harmful effects on human health and the environment.
What material causes the destruction of the ozone layer?
CFC's cause ozone destruction. They react with ozone to deplete it.
Do CFCs strengthen the ozone layer?
No, the chlorine and other chemicals in CFCs (chlorofluorocarbons) destroy the ozone molecules and weaken the ozone layer.
What does CFCs do to the ozne layer?
CFC's go in the ozone layer. They deplete the ozone.
What is the main cause of destruction of the ozone layer?
The main cause of destruction of the ozone layer is the release of man-made chemicals called chlorofluorocarbons (CFCs) into the atmosphere. When these CFCs reach the stratosphere, they break down ozone molecules, leading to a reduction in the ozone layer's thickness.
What are the two components which deplete the ozone layer?
Chlorofluorocarbons (CFCs) and halons are two components that contribute to the depletion of the ozone layer. These chemicals break down ozone molecules when they reach the stratosphere, leading to thinning of the ozone layer.
Which chemical is mainly responsible for depletion of ozone layer in the atmosphere?
Manmade chemicals like chlorofluorocarbons and bromofluorocarbons are the major depleters of the ozone layer. The chlorine and bromine separate from the CFCs (chlorofluorocarbons) and destroy the ozone molecules.
Chemical responsible for ozone layer depletion?
Chlorofluorocarbons (CFCs) are the main chemicals responsible for ozone layer depletion. Once released into the atmosphere, CFCs can reach the stratosphere where their chlorine atoms can destroy ozone molecules.
