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.

depleting ozone molecules through a chemical reaction once they reach the stratosphere. This reaction breaks down ozone molecules into oxygen molecules, leading to a thinner ozone layer that allows more harmful UV radiation to reach the Earth's surface.

∙ 10y 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.

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,
Why is ozone considered a pollutant in the ozone layer?
Ozone is considered a pollutant in the ozone layer when it is in high concentrations because it can cause damage to living organisms and materials. In the stratosphere, where the ozone layer is located, excess ozone can lead to health issues for humans, harm ecosystems, and reduce crop yields.
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 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.
What happens when a meteor hits the ozone layer?
When a meteor hits the ozone layer, it can cause localized heating and disruption of the ozone molecules. This can lead to a temporary thinning of the ozone layer in that specific area, which may allow more harmful UV radiation to reach the Earth's surface. Over time, the ozone layer can repair itself and return to its normal state.
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,
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 ozone considered a pollutant in the ozone layer?
Ozone is considered a pollutant in the ozone layer when it is in high concentrations because it can cause damage to living organisms and materials. In the stratosphere, where the ozone layer is located, excess ozone can lead to health issues for humans, harm ecosystems, and reduce crop yields.
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.
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.
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.

Over time, the ozone layer can repair itself and return to its normal state.
What problems may occur if ozone layer disappeared?
If the ozone is destroyed, it will cause mass extinction. Mankind will perish.
