Chlorine breaks off from CFCs and destroys the ozone.
Ozone is a protective layer in the upper atmosphere. It is formed, when oxygen molecules absorb short wavelength ultra violet radiations from the sun. Ozone is mostly destroyed by free radicals in the atmosphere.
When compounds like CFCs (chlorofluorocarbons) and other halocarbons are released, they are dissociated by sunlight into chloride radicals. These radicals attack ozone, thereby decreasing its concentration. This results in a thinning of the ozone layer, and in polar regions, a hole.
The holes occur at the poles, and usually in Antarctica because of the extreme cold. During the winter polar stratospheric clouds form which are able to convert gases in the atmosphere into Cl (chlorine) and ClO (chlorine monoxide). When the sun arrives at the end of winter, that is the trigger to begin. This is why the hole is largest in spring.

∙ 11y agoThe CFC's go into the stratosphere and there they cause ozone depletion by breaking down the ozone molecules. If the ozone layer keeps breaking down, then there will soon be a hole in the ozone layer which will take 50 years to heal.

CFCs once ised in many household products contributed to the creation of ozone hole true or false?
it does not cause the creation of the ozone.
How did the hole in ozone layer occur and is it related to global warming?
The hole in the ozone layer came about because of the artificially produced gases CFCs (chlorofluorocarbons). These contained chlorine and bromine which destroyed ozone. CFCs are now banned. The ozone hole has very little to do with global warming.
Can the hole of the Ozone Layer be repaired?
The ozone hole can be repaired by curbing the use of CFCs. If there are no man made ozone destroying substances, the ozone layer will replenish itself.
What human-made chemicals cause the ozone to deplete?
The human made chemicals that destroy the ozone are CFCs. These CFCs are ones that decompose the ozone molecules.
What should you do to decrease the impact of ozone layer depletion?
In order to decrease the impact of ozone depletion, we should curb the use of CFCs. It is because in the absence of these CFCs, the ozone hole will automatically replenish.

it does not cause the creation of the ozone.
What is meant by the hole in the ozone layer what role does CFCs have in it?
The thinning of ozone layer is called as ozone hole. CFC's are the ones that create the ozone hole.
How did the hole in ozone layer occur and is it related to global warming?
The hole in the ozone layer came about because of the artificially produced gases CFCs (chlorofluorocarbons). These contained chlorine and bromine which destroyed ozone. CFCs are now banned. The ozone hole has very little to do with global warming.
What can CFCs cause ozone depletion?
CFC's react with ozone to cause depletion. they decompose the ozone layer.
What causes the ozone hole to expand?
As the CFCs are carried to Antarctica there is a big ozone hole. Chlorine and bromine atoms from CFCs (chlorofluorocarbons) separate and destroy ozone molecules, but remain active for several years continuing their destruction. So if more CFCs will be produced in the world more CFCs will be carried to Antarctica by the polar winds and more depletion and the rate of depletion will exceed the rate of formation of ozone molecules resulting in the expansion of ozone hole over Antarctica.
Why are humans causeing the hole in the ozone layer?
Humans are causing the hole in ozone layer by using CFCs. These CFC are the factors responsible for depletion of ozone.
What cause the ozone to break down?
CFCs
Can the hole of the Ozone Layer be repaired?
The ozone hole can be repaired by curbing the use of CFCs. If there are no man made ozone destroying substances, the ozone layer will replenish itself.
What human-made chemicals cause the ozone to deplete?
The human made chemicals that destroy the ozone are CFCs. These CFCs are ones that decompose the ozone molecules.
What group of chemicals have contributed to the hole in the ozone layer?
CFCs, or chlorofluorocarbons.
What should you do to decrease the impact of ozone layer depletion?
In order to decrease the impact of ozone depletion, we should curb the use of CFCs. It is because in the absence of these CFCs, the ozone hole will automatically replenish.
How can we affect CFCs?
CFC's are compounds which cause ozone depletion. They decompose ozone.
