No, not smoke. Chlorofluorocarbons (CFCs) released in the second half of last century is still damaging the ozone layer. Chlorine separates from the CFCs and attacks 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.
What else can I help you with?
What chemicals are causing the ozone layer thinning?
CFC's cause hole in ozone. They react with ozone and deplete it.
In 1985 a hole in the ...was discovered over Antarctica.?
yes, and it was the "antarctic ozone hole"ozone layer
Why is threre a hole in the ozone layer?
The hole in ozone layer is the thinning of layer of ozone. It is because of the CFC's released by humans.
What Hole is in the ozone layer?
There is not actually a hole in the ozone layer. The ozone has been reduced below some limit.
Why is there a ozone hole?
Ozone hole is the thinning of ozone layer. It is due to ODS.
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.
Why is burning garbage bad?
The chemicals in its smoke make a hole in the ozone layer. As long as there is a hole in the ozone layer, it becomes harder to fight global warming.
What does pollution do to the ozone?
Pollution depletes the ozone layer, and is causing a hole in it right above Antarctica.
Was there a hole in the ozone layer?
Yes, there was a hole in the ozone layer.
What chemicals are causing the ozone layer thinning?
CFC's cause hole in ozone. They react with ozone and deplete it.
Hole in UV layer?
There is no hole in UV but in ozone layer. And the hole in ozone layer is actually the thinning of the layer.
Are green house gas emissions good?
No, they are causing a hole in the Ozone Layer.
In 1985 a hole in the ...was discovered over Antarctica.?
yes, and it was the "antarctic ozone hole"ozone layer
Is the hole in the ozone layer causing cancer?
Yes it is causing. It causes the UV's of the sun and they cause cancer.
How do you mend the hole in the ozone layer?
See "Can the hole in the Ozone layer be fixed?"
How do chlorofluorocarbons damage ozone?
See "What is causing the depletion of the ozone layer?"
Why is threre a hole in the ozone layer?
The hole in ozone layer is the thinning of layer of ozone. It is because of the CFC's released by humans.
