What instrument is UV RAYS used?
UV rays are not produced by any musical instrument. UV rays are a form of electromagnetic radiation that comes from the sun and can cause skin damage and other health issues.
How is ozone in the stratosphere the same as the troposphere?
No. The ozone is stratosphere is good ozone. The ozone in troposphere is bad ozone.
Name three daily changes which might affect plants and animals?
What are the layers called that protect us from uv rays?
The "ozone" layer is particularly important for absorbing UV rays since the molecular bonds in ozone vibrate at the frequency of UV radiation and absorb it quite well. The ozone layer lies near the bottom of the stratosphere.
Note that UV radiation spans a range of frequencies. UV-A is the least absorbed/reflected UV radiation. Mostly the atmosphere lets it through. UV-B is absorbed mostly by the ozone in the atmosphere - mostly in the ozone layer in the stratosphere, but there is ozone at all layers of the atmosphere. UV-C is absorbed by the oxygen and nitrogen in the atmosphere - so very little of that makes it through; the atmosphere is about 78% nitrogen and 21% oxygen.
No, it can thin the layer though.
The hydrogen carried with a coronal mass ejection does depress ozone levels (more towards the south pole), but this happens days later than the accompanying solar flare.
The largest "hole" we have ever known about occurred the same year as the largest known solar flare activity. This happened in 1859.
What protects the earth from meteorites and deadly rays?
The ozone layer present in the stratospheric region of the atmosphere protects the earth from the dangerous rays coming from the sun. These radiations are known as ultraviolet radiations and can cause problems like skin cancer and eye cataract in humans.
What does ozone mean in science?
Oxygen molecule, generally it is O2 and is what we breath in. As in Oxygen goes into our body to carry out aerobic respiration.
What is the highest level of ozone?
In the ozone layer, ozone typically reaches as high as 9 ppm. In an oxygen fed ozone generator, ozone concentration can reach in excess of 300 mg/SL (>15000 ppm). Ozone can been liquified up to 100% concentration.
What can you do to protect ourselves from the uv rays that get through the ozone layer?
To protect yourself, curb CFC's. They are the ones causing depletion.
Can polluton make the ozone layer thinner?
No. CFCs from man are causing the hole in the ozone layer.
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.
Another view:
Unfortunately many people confuse the natural hole that we see annually in the ozone layer over the Antarctic, with the possibility of ozone depletion over the entire planet. CFC's, while not a significant factor are not a major factor in this annual event that has always occurred since the atmosphere first contained oxygen.
Looking at the complete picture we see the major reasons for the hole include:
1. Natural chemical reactions (this is why the hole is so much larger in the Antarctic then the dimple in the Arctic
2. Seasonal variations in sunlight. (Ozone is naturally decays into oxygen, so we need sunlight to create more ozone) This is why the hole only occurs during the long winter months
3. Special isolation issues associated with the Antarctic
4. ozone depleting chemicals from nature and man. (anything with chlorine. like salt water)
5. Volcanic aerosols and stratospheric clouds.
The lack of sunlight hitting the Antarctic causes this very natural event and is exacerbated by the other conditions. This is also why the ozone returns to normal within weeks of daylight returning to the area. We know that this hole has been happening for many years before the invention of CFC's by man. In fact, the largest single thinning of this layer happened with zero CFC's present. Solar discharges in 1859 caused the single largest thinning of the ozone layer. In just this one event, it managed to thin the layer by 5%.
Check out the related peer review article below that explains the nature of the hole and why it is predominately a natural event.
Ozone is made both by Nature (ozone layer, lightning, waterfalls, and as an oxidant produced to fight infection), by Man (oxidant used for many industrial, and commercial uses), and by both together (ozone pollution).
Oxygen gas is O2 . Ozone is O3. The ozone-producing reaction is 3O2 ---> 2O3 . This reaction is endothermic - it needs energy input from outside. Most ozone existing on earth is produced very high in the atmosphere; the necessary energy comes from ultraviolet radiation in raw sunlight. A much smaller amount of ozone is produced in the lower atmosphere by the action of electric arcs (sparks) on oxygen. This production of small quantities of ozone is what gives electric sparks their characteristic smell.
Can airplanes fly in the Ozone layer or the Ionosphere?
yes. They normally don't, because it was found they were damaging it. But they do fly through it when flying between continents (Moscow to New York, for example). The ozone layer dips pretty low over the poles.
What causes the depletion layer?
Depletion layer The area in a P-N junction that is free of (i.e., depleted of) current carriers.
Where is the ozone layer thin?
Inferences of how much ozone is overhead depends on how much UV-B arrives at Earth's surface. Once every 13,000 years, the pole facing the Sun (summer there) moves from being closest to the Sun, to being farthest from the Sun (precession). Right now, it is the South pole's turn to be closest in summer. So some effect will be simply that there could be the same amount of ozone, and Australia will still get more UV-B. Additionally, the magnetic field of the Earth directs more hydrogen (aka. cosmic rays) from the Sun to the South pole. Hydrogen oxidizes to water vapor, and water vapor performs a one-two punch... depleting some ozone. This is why the ozone hole is larger at the South pole than at the North pole, even depressing ozone levels as far away as Australia. Then throw in the depleting effects of Man, over-the-pole aircraft flights, release of chlorine- and bromine-containing gases, and Nature's own efforts via volcanos, and all countries see an increase in UV-B arriving at Earth's surface.

Why there is more concentration of ozone in antarctic area?
A number of reasons stand out:
# It is far from civilization, with its ozone-as-smog, # It has an annual "feature", an ozone "hole" that is larger and "deeper" than its northern counterpart, # It is now manned year-round, # It belongs to no nation, so there are no "diplomatic" issues involved in multi-national studies, and # It is largely based on a continent, with real land underneath.
Why the ozone layer is important to our earth's atmosphere?
There are several things to be argued about the ozone layer, including the fact that humans are causing it to be destroyed, but the main thing is the ozone layer is such a hot topic because it is the only thing between us and being fried by solar radiation.
What type of things destroy the atmosphere?
We harm the atmosphere in many ways. We smoke, and build things that put chemicals in the are harming the atmosphere. People could make things to keep from polluting the air. We are intelligent people, we can do anything we set our minds to.
Why should you continue to monitor the ozone?
It is a measure of depleting chemicals. We have staff near the South Pole, and they can do this monitoring too.
See "What makes scientists think the ozone layer is thinning?"
How many elements are ozone part?
There is one element, oxygen, in ozone. Each molecule of ozone contains three atoms of oxygen.
What would happen if we lost the ozone layer?
Nothing. More would be made right away, since it is very unstable and is constantly replaced (at some level).
What does ozone Action day means?
An Ozone Action Day is a term used to describe a day on which the local weather forecast predicts that ground-level ozone concentrations will reach unhealthy levels. Ozone is a gas that is naturally present in the upper atmosphere (stratosphere), but when it is present at ground level, it can be harmful to human health and the environment.
During an Ozone Action Day, air quality agencies typically issue alerts to warn the public about the expected high ozone levels. These alerts are intended to inform people about the potential health risks associated with exposure to high ozone concentrations and to encourage them to take action to reduce their exposure.
Ozone Action Days are most common during the summer months when temperatures are high, and the sun is strongest. Ground-level ozone is created when emissions from vehicles, industrial facilities, and other sources react with sunlight. The heat and sunlight can exacerbate the formation of ozone, leading to higher concentrations on certain days.
The purpose of Ozone Action Day is to alert people of the potential health risks associated with exposure to ozone pollution, so they can take steps to protect themselves and their families. For example, people with respiratory issues, such as asthma, may want to limit their outdoor activities on an Ozone Action Day. Similarly, people who are sensitive to ozone may want to avoid going outside during the hottest part of the day, when ozone levels are typically highest.
To reduce ozone pollution and the number of Ozone Action Days, there are steps that individual, organizations and government can take such as:
Reducing car usage and driving more efficiently
Avoiding idling vehicles when possible
Walking, biking or taking public transportation
Conserving energy by turning off lights and appliances
Supporting local and national policies that promote clean air
Planting trees, grass and other plants that absorb pollutants
In summary, An Ozone Action Day is a term used to describe a day on which the local weather forecast predicts that ground-level ozone concentrations will reach unhealthy levels. The purpose of Ozone Action Day is to alert people of the potential health risks associated with exposure to ozone pollution, and to encourage them to take actions to reduce their exposure and to reduce ozone pollution. Therefore, it's important to be aware of the air quality forecast, especially on the warmer months, and take actions to protect yourself and your community.
Depletion is when something goes down. For example: Let's say you had many people and a large amount of food. Over time that food will start to deplete (go down), until there is nothing left.
How. Far does the stratosphere extend?
the stratosphere is 50 kilometers away from the earth's surface, and the troposphere is 12 kilometers away from earth's surface. that means that the stratosphere is 38 kilometers. Hope i helped!
Why is the ozone layer important to the earth's atmosphere?
The ozone is an important layer found in the stratospheric layer of the Earth. It is important because it protects us from the UV (Ultraviolet) rays of the sun. However the ozone layer is getting depleted due to the emission of harmful gases like CFCs (Chlorofluorocarbons)
