Uvb Radiation The Reaches The Earths Surface
982 wordsOur Radiant Planet- Depletion of the Ozone Layer Ozone is a relatively unstable form of molecular oxygen containing three oxygen atoms produced when upper-atmosphere oxygen molecules are split by ultra violet light. Stratospheric ozone is found in a broad band, extending generally from 15 to 35 km above the earth. Although the ozone layer is surprisingly thin, it acts as a protective shield to the earth, as it filters out most of the harmful solar ultraviolet radiation (in particular UV-B) that ...

Layer Of Chemicals
1,478 wordsStudy of Environmental Issues Associated with Industrialization Although our industrial ways seem to be a very progressive step into the future, there are many flaws to the way many things are today. Things have definitely changed over the past century, as we can currently do things much more efficiently then before. The cost of this efficiency may seem inexpensive in many ways, however we do not realize that the cost of these new technologies do not just include money, time and labour, but it a...

Oxygen Atoms On The Ozone Molecule
2,327 wordsCfcs Cause Deterioration of the Ozone Layer The deterioration of the ozone layer, caused by Cfcs, endangers the lives of humans'. Cfcs have a diminishing effect on the ozone layer. Furthermore, the deterioration of the ozone cause an increase of Ultraviolet (UV) radiation which can have a negative effect on human skin and eyes. As a writer for newsweek, I have investigated the scenario and found the following information. The earth's atmosphere is a blanket of air that surrounds the planet. This...

Greenhouse Effect And The Ozone Deletion
679 wordsWe are living in the midst of a great chemical experiment, and some serious consequences are becoming apparent to scientists. More than two billion pounds of chemicals are spewed into the air each year. These chemicals are brewing a disastrous stew, resulting in an atmosphere crisis. The greatest consequences of the atmosphere crisis may be the greenhouse effect (global warming) and the ozone deletion. If humankind wants to survive well into the next millennium, than we must stop this horrid des...

Cfc Destruction Of The Ozone Layer
1,315 wordsOzone Depletion Case for " Ignoring the Facts" Ozone forms a layer of the earth's atmosphere that protects us from the sun's deadly ultraviolet rays. During the last decade there has been a scare set forth by environmental enthusiasts that Chlorofluorocarbons (CFCs) destroy the ozone layer. Although there has been no evidence of any CFC destruction of the ozone layer there is an international stoppage on using CFCs, as well as an executive order set forth by Clinton to limit the sell and use of ...

Ozone Near The Earth's Surface
1,589 wordsThe Ozone Layer In environmental science the green house effect is a common term for the role water vapor; carbon dioxide and ozone play in keeping the earth's surface warmer than it would normally be. The atmosphere is primarily transparent to infrared radiation from the sun, which is mostly absorbed by the earth's surface. The earth being much cooler than the sun, remits radiation most strongly at infrared wavelengths. Water vapor, carbon dioxide and ozone then absorb much of this radiation an...

Hole In The Ozone Layer
282 wordsBut there is a significant pending problem in the ozone layer. Each year, a large hole appears in it. It is not an actual hole, like a hole in a pocket, but a thinning in the layer that shows up on satellite pictures. The 'hole' is located over Antarctica. It covers an area about the size of the United States. Experiments done in Antarctica show that the hole in the ozone layer appears to let in twice as much ultraviolet radiation as normal, according to measurements researchers made there only ...

Ozone In The Upper Atmosphere
626 wordsOzone, pronounced OH Z ohn, is a form of oxygen that is present in the earth's atmosphere in small amounts. Ozone in the upper atmosphere is a major factor in making life on earth possible. But ozone in the lower atmosphere contributes to air pollution. Ozone is used commercially in water purification process and as a bleaching agent. Ordinary oxygen molecules have two oxygen atoms, ozone has three. Ozone is produced naturally through photochemical and electric discharge reactions. Photochemical...

Ozone Layer Ozone Layer Depletion
489 wordsThe Ozone Layer Ozone layer depletion slows There is good news about the ozone layer above us. The good news about the ozone layer is not always frequent. On International Ozone Day, the report came in that the ozone levels have decreased above Montreal and other residents of southern Canada. The ozone levels have decreased to a normal level. Normal meaning the levels have dropped from the levels reported in 1980. The ozone layer is an important and fragile part of earth. If we did not have an o...

3 The Result Of Ozone Layer Depletion
1,351 wordsAtmospheric ozone layer depletion is a serious problem currently facing the world. The ozone layer protects humans, animals, and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists. The ozone layer is a region of the stratosphere containing ozone, or O 3 gas. The ozone layer is essential to both plant and animal life on earth because it protects the surface from dangerous ultraviolet light. However, industrial and domestic chemicals ...

Global Effects Even With The Ozone Layer
918 wordsOzone Layer Thinning Caused By CFC's The ozone layer. What really is the ozone layer, and what does it do Is it just a plastic covering over the earth Why do we depend on the ozone layer so much for the earth's survival Without the ozone layer there would not be life on this earth. It protects us from all the bad UV ray from the sun, so we do not get skin cancer and die. It also keeps in the heat so we would not freeze to death. Also it lets in the sunlight heat in. That is why the ozone layer i...

Ozone Layer Causes
817 wordsSociety has been widely addressed with the many problems that we are having in our environment today. A major problem is that of CFCs. CFC stands for Chlorofluorocarbons which are found in many of the aerosol spray cans. In December of 1973, Rowland and Molina discovered that CFCs can destroy the ozone in the stratosphere. In June 1975, the Natural Resources Defence Council (NRDC) sued the Consumers Product Safety Commission for a band of CFCs used in aerosol spray cans. United States's fifth la...

Chlorine On The Ozone Layer
1,396 wordsThe Earths ozone layer shields all life on the planet from the suns harmful radiation and is extremely important to all life on the planet, but we as a human race are now faced with a very important question. This question is, Is the Earths ozone layer really depleting, and if it is, is it really a threat There is evidence that less protection from ultraviolet rays will, over time, lead to increased amounts skin cancer, cataract, and even crop damage. With cooperation with over 140 oth countries...

Destruction Of The Ozone Layer
862 wordsAbove the earth, approximately 30-50 kilometers, a layer of stable oxygen atoms covers the stratosphere, this called the ozone layer. It protects "all life" from the sun's harmful radiation. (US EPA). The ozone layer is very powerful; it protects the earth from dangerous UVB rays from the sun. (Frank 13) If the rays from the sun were to pass through the atmosphere it would be devastating because they have the ability to destroy skin cells in humans and animals. In 1974 two scientists discovered ...
