Stratospheric Ozone Hole
2,448 wordsThe Atmospheric Ozone Layer The stratospheric ozone layer exists at altitudes between about 10 and 40 km depending on latitude, just above the tropopause. Its existence is crucial for life on earth as we know it, because the ozone layer controls the absorption of portion of the deadly ultraviolet (UV) rays from the sun. UV-A rays, including wavelengths between 320 and 400 nm, are not affected by ozone. UV-C rays between 200 and 280 nm, are absorbed by the other atmospheric constituents besides o...

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...

Odp For Ch 3 Br
579 wordsMethyl Bromide The Crop Protection Coalition (CPC) suggests that the scientific foundation for the phase out of methyl bromide (CH 3 Br) may not be justified. The implication of the CPC is that the effects of CH 3 Br on stratospheric ozone is likely to continue to decrease because there was a decreasing effect noted as the science progressed through the 1990's. However, the science community completed a major new assessment of stratospheric ozone (Scientific Assessment of Ozone Depletion: 2002; ...

Depletion Of The Ozone Layer
2,359 wordsThe Poisoning of Our Ozone Layer The poisoning of the Earths ozone layer is increasingly attracting worldwide concern for the global environment and the health effects of life on the Planet Earth. There is not just one particular cause for the ozone depletion; the accumulation of different pollutants into our ozone layer has all added up and equaled a worldwide problem. There is not just one effect from the poisoning of the ozone, but instead multiple ramifications from diseases to death. The da...

Natural Cause Of Ozone Depletion
928 wordsThe ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger, additional ultraviolet rays are allowed to pass through. These rays cause cancer, cataracts, and lowered immunity to diseases. 1 What causes the depletion of the ozone layer In 1970, Cru tzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started research on...

Polar Stratosphere And Slow Ozone Destruction
1,552 wordsThe reappearance of the ozone hole over Antarctica has been a hot topic for scientist around the world. A few of these scientists are the atmospheric physicist Richard D. Mc Peters and several of his colleagues at the NASA Goddard Space Flight Center in Greenbelt. The ozone hole showed up earlier than expected, and it was wider and thinner. It appeared in mid-August, about two weeks ahead of schedule, and on September 19 reached the record size of 10.5 million square miles, more than three and a...
