Why ozone layer depleted in poles rather there is no pollution there?
Pollution is not a ozone layer issue. The "hole" in the ozone layer is a thinning of the layer (mostly above the South Pole) that occurs each year for a short period (about 4 months total cycle) because the sun is unable to hit the layer. Ozone is a very unstable element and with energy from the sun it degrades into simple oxygen (O2). The layer is normally about 3 mm thick and once a year, when the sun can not hot the layer, it degrades to about 1 mm.There is some trace amounts of a few items such as CFC's in this area. These gases do have the ability to react with ozone.
In which year was the ozone layer biggest?
The ozone layer covers the entire planet twice a year, every year. That is when it is biggest.
What year did the hole in the ozone get discovered?
The discovery of the hole in the ozone layer was officially announced in 1985. British scientists reported that the ozone layer above Antarctica was significantly depleted. This discovery led to global concern about the effects of ozone depletion on the environment.
Is there any improvement of ozone layer in recent year?
Yes, there is. Ozone layer is replenishing.
How fast is the ozone layer growing each year and why?
The ozone layer is growing slow. This is due to ozone depletion by CFC's.
How fast is the ozone layer disappearing?
There is no clear evidence that the ozone layer is monotonically disappearing. Sometimes the hole is larger than others, and we believe the Kyoto protocol (banning CFCs) limited the damage we were doing to the ozone layer. Eventually those CFCs will leave the tropopause, but there will still be an ozone hole. In the winter at the poles, there is little UV to make new ozone. So if there is any water vapor, ozone will be naturally depleted.
What happened with the ozone layer?
As an indicator of ozone layer health, the "ozone hole" was at near record size last year. No real indicator that the ozone layer is healing. But if someone doesn't jump up and down on the panic button continuously, it is very easy for the anti-greens to make up snide remarks like the one shown above. Please see the link below for an ozone layer watch site.
When was the ozone layer discoverd?
The ozone layer was discovered in the year 1913 by the scientists Charles Fabry and Henry Buisson.
What year do scientists think the ozone layer will have rebound?
Scientists hope the ozone layer will have recovered by around 2050.
Has size of the hole in the ozone layer changed in recent year?
Yes, it has. Size of ozone layer changes according to the use of CFC's.
What is the size of the ozon layer this year of 2008?
The size of ozone layer in year 2008 was moderate. It was recovering.
Does a thick unchanging layer of the ozone cover the entire earth?
No, the ozone layer is not a single thick layer covering the entire Earth. Instead, it is a region of the stratosphere that contains higher concentrations of ozone gas. The thickness and concentration of this ozone layer vary depending on factors such as location and time of year.
