Ozone Layer
The ozone layer is a crucial layer in the Earth's atmosphere that absorbs and blocks out harmful ultraviolet light that can damage Earth.
3,889 Questions
The ozone hole is the thinning of ozone layer. It is formed due to use of CFC's.
What is the difference between stratospheric ozone and photochemical ozone?
Stratosphere ozone is good ozone. Photo chemical ozone is pollutant.
Why people don't believe in the ozone layer?
People do not believe in ozone layer as they haven't seen it. It is located far above in atmosphere.
How far do greenhouse gases extend into the atmosphere?
Greenhouse gases extend very high. They extend in the troposphere.
Would ozone in front of a source of UV light form a shadow on a suitable indicator screen?
Yes, ozone absorbs UV light, so it would block the UV rays from reaching the indicator screen. As a result, a shadow may be observed on the indicator screen where the ozone is present in front of the UV light source.
How did the formation of the ozone layer permit organisms to colonize land?
they stopped the harmful sun rays from penetrating and thus made the conditions for more suitable for life...
Why are scientists concerned about ozone depletion?
Scientists are concerned about the ozone layer as the reduction of ozone could cause a number of problems. These are eye cataract and skin cancer.
Does the hole in the ozone layer let heat out?
Yes, it can. The absence of ozone causes all the rays to pass through.
Where is thinning of ozone most evident?
The thinning of ozone layer is most pronounced at the poles of the earth. It is because of the low temperature of the low temperature there.
The ozone depleting reactions are carried on the polar stratospheric clouds i.e. the PSC's. these PCS's require minimum temperature for their formation which is possible only on the poles.
Will recovery of the ozone layer be a rapid or a slow process if so why?
It can be slow or fast. It depends upon how CFC's are released.
Where is the big whole in the ozone layer?
The big hole(whole) in the ozone layer is over poles. The poles carry these holes.
What makes lightning when it is thundering?
When it is thundering, there is lightening. Lightening creates ozone.
Does cigarette smoke affect the ozone l?
Yes,cigarette smoking affect ozone. But the amount is very low.
What is atmosphere and ground ozone?
The good ozone is a pollutant. While the atmospheric ozone is useful as it protects us from Uv rays.
What are the pirmary culprits in ozone layers breakdown and how did they get in the stratosphere?
CFC's are the primary culprits for depletion. The get in the stratosphere by the westerly winds.
What is a bigger deal the greenhouse effect or the destruction of the ozone?
Hard question. Global warming will flood low lying areas, destroying some arable land and producing other arable land. The legal system will be challenged, because waterways (which will be moving) are commonly a boundary for property definitions. So it will make lots of jobs for lawyers. Intensities and frequency of storms will increase, so again the insurance companies and lawyers make out. Ozone depletion could possibly increase cataracts, cancer (in people and our food supplies), and mutations. But the denialists are busy making excuses to cover Big Industry, so there is no way we can pin them down. No jobs for lawyers, no jobs for farmers / ranchers, no food for the masses, no place to hide except underground... like the Morlocks. Or not.
How much thinner has the ozone gotten?
The variances are great. The largest hole was back in 1856, before CFC's were in wide use. The equator has seen almost zero loss at any time. The poles show loss during thir winter seasons. Scientists know this is due to a loss of sun in that area. They believe CFC's may help make this hole larger during the winter.
Where can you purchase a UV sterilizer?
You can get a great deal on a UV sterilizer in your local electrical store. Failing that, you can try local ads in your paper, or sites such as Craigslist, Amazon or eBay.
What is the result of losing the ozone layer?
Answer is: "Loss of 70% of the Earth's Oxygen Generating Layer that is known as Phytoplankton"; is bad News indeed.
What is another name for bad ozone?
Bad ozone is the common name. The name for bad ozone is ground level ozone. It is because most of it is present as a ground level pollutant.
What are the objects found on troposphere?
Troposphere is the layer closest to earth. All the cloud formation happens in troposphere only.
Ozone is a molecule made of 3 oxygen atoms. It is formed by the action of UV light on Oxygen high up in the upper atmosphere. Ozone filters out UV light from reaching the surface of the earth and thus acts as Earth's sun screen.
Ozone is destroyed by the presence of man made CFC gasses in the atmosphere (propellants used for spray cans and as the refrigerant is fridges). The CFC gases destroy the Ozone and thus where the Ozone layer is thinnest (over the poles where the Sun's UV light is weakest) the Ozone disappears and a hole is formed.
