Chlorofluorocarbons (CFCs) were emitted during the 20th century from aerosols, refrigerators and other appliances. When CFCs reach the ozone layer (up to ten years later) the chlorine molecules separate and destroy ozone molecules. The chlorine survives and lives to fight again. CFCs can remain in the atmosphere for up to 75 years. CFCs are no longer being emitted to the atmosphere and scientists hope the ozone layer will have repaired itself by 2060.

∙ 9y agoChlorofluorocarbons are so hardy, they survive being lofted to the upper atmosphere, where the only thing that can break them down, UV, releases the chlorine from the molecule. The chlorine is then free to break down ozone, and be reactivated to do it over and over again.
Chlorofluorocarbons may be harming the ozone layer by adding more ozone molecules, blocking ultraviolet light, or by destroying ozone molecules.

Why is ozone considered a pollutant in the ozone layer?
Ozone in the ozone layer is not at all a pollutant but it is something without which no ozone layer may have existed. Ozone can be considered as a pollutant in the stratospheric region but in the stratosphere or the ozone layer it is of full or complete use. No harms there.
What can lead to the depletion of the ozone layer of earth?
Ozone layer depletion is the depletion of ozone. It has very bad affect on environment,
What part is the ozone layer?
There are no parts to the ozone layer. Ozone is found in all layers of the atmosphere, with near zero concentrations at very high altitudes and near the Earth's surface. The lower portion of the stratosphere reaches peak ozone concentration (9-10 ppm), and this is usually referred to as the ozone layer. In the winter at one of Earth's poles, an ozone hole forms. The size of the is a function of contaminants that may be found at those altitudes that accelerate the otherwise natural decay of ozone.
Why is ozone layer disappearance a problem?
The ozone layer is not disappearing. The ozone layer may or may not be thinning.A thinning ozone layer results in increased rates of cancer and mutation, and reduced crop yields and loss of arable land.
What is the effect of CFCs on the ozone layer?
The CFCs are broken down, releasing chlorine in the process. The chlorine then breaks down the ozone in the stratosphere to form oxygen. When the ozone is broken down at a quicker rate than it can reform, holes in the ozone layer may appear. This allows more UV radiation to reach the surface of the earth and it is an issue in the southern hemisphere.CFC's react with ozone layer. This reaction causes their decomposition.
Chloroflourocarbons may be harming the ozone layer by?
CFC's may be harming the ozone layer. They do it by depleting the ozone, decomposing into single atoms.

What chemicals may be thinning out the ozone layer?
CFC's that is chlorofluorocarbons are responsible for thinning out ozone layer. These chemicals start a chain reaction within the ozone layer.
What can lead to the depletion of the ozone layer of earth?
Ozone layer depletion is the depletion of ozone. It has very bad affect on environment,
CFC's may cause ozone depletion by?
CFC's may cause ozone depletion by reacting with ozone. They react and decompose them to form other chlorine and fluorine compounds thus depleting the ozone layer.
What is harming the ozone layer?
This has been answered under other categories: # Water vapor both blocks one path of ozone formation, and provides a faster decay path for ozone. Water vapor arrives in the "ozone layer" from both natural and Man-caused sources. # CFCs have been shown to catalytically destroy ozone, and stick around long enough to do it again and again. CFCs are entirely Man-caused. Other catalysts may source from volcanos, etc.
Why is damaged to the ozone layer cause of concerned?
The ozone layer stops harmful radiation from reaching the Earth's surface. Depletion of the ozone layer increases the risk of skin cancer. It may also affect the ecosystem in unpredictable ways.
Could the ozone layer be present in homes?
Ozone may be present in extreme trace amounts and it is air pollution, but the ozone layer can only be in one place; 10 to 50 kilometres up in the atmosphere.

What problems may occur if ozone layer disappeared?
If the ozone is destroyed, it will cause mass extinction. Mankind will perish.
