Myths And Legends Oxygen Atoms
878 wordsIn certain polar regions of the earth, a rare and fascinating phenomenon occurs in the dark season of winter. This phenomenon is called the Northern Lights, or auroras. In areas where auroras can be seen, the sun shines brightly for six months and then disappears for the next six. The sun follows a straight path across the sky, rising in the north and setting in the south. This is because of the latitude of these regions. Unlike other regions of earth, the polar regions either completely face th...

Chlorofluorocarbons Cfcs Nitrogen Oxides
1,336 wordsDramatic loss of ozone in the lower stratosphere over Antarctica was first noticed in the 1970 's by a research group from the British Antarctic Survey (BAS) who were monitoring the atmosphere above Antarctica from a research station. The Halley Research Station BAS research stations in the Antarctic Rumor has it that when the first measurements were taken in 1985, the drop in ozone levels in the stratosphere were so dramatic that at first the scientists thought their instruments were defective....

Depletion Of The Ozone Layer
1,370 words... portion of the ozone layer is a major concern today. The ozone layer protects us from the harmful rays of the sun; therefore it is imperative that we preserve it. Since more pollutants are produced today than ever before (because of the major increase in the population), there is a major concern that we create less pollutants to help conserve the ozone layer. In this research paper I will give vital information on how pollution affects the ozone layer and methods instituted to help the ozone...

Effects Of Acid Rain Sulfur Dioxide And Nitrogen
3,730 wordsWhat is acid rain? Acid rain is the term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture. The term 'acid rain' is slightly misleading, and would be more accurate if deemed 'enhanced acid rain', as rain occurs acidic naturally. Acidity is measured on what is know as the pH scale. Fourteen is the most basic, seven is the most neutral, and zero is the most acidic. Pure rain has a pH level of 7, which is exactly neutral. The acidity of rain is determined by t...

Piece Of Paper Oxygen Molecules
1,524 wordsIn 1839, a German scientist Christian Schonbein was a professor of chemistry at the University of Basel in Switzerland. In addition to his teaching duties, he regularly performed secret experiments in hopes of finding out which substances make up the Earth's atmosphere. So Schonbein combined and separated a number of liquids and gases. During one of these experiments, Schonbein passed an electric charge thought a glass beaker of water, be noticed a very familiar odor. He first thought it was the...

Hydrogen Atoms Oxygen Atoms
824 wordsTwo Americans and a Japanese were awarded this year's Nobel Prize in Chemistry for developing more efficient chemical reactions to produce many medicines, including L-dopa, the standard treatment for Parkinson's disease. Dr. William S. Knowles, 84, of St. Louis, who retired from the Monsanto Company in 1986, and Dr. Ryoji Noyori, 63, director of the Research Center for Materials Science at Nagoya University in Japan, shared half of the $ 950, 000 award.

Amount Of Energy Oxygen Atoms
1,983 wordsPlanning In this investigation I will be burning alcohols to heat up a beaker of water. I will be burning five alcohols, methanol, ethanol, propanol, butanol and pentanol. The aim is to find out how much energy is produced when burning these alcohols. An alcohol is a series of organic homologous compounds, with the general formula Cn H n + 1 OH´ . Alcohols react with oxygen in the air to form water and carbon dioxide. The reaction that is involved in burning alcohols is exothermic because ...

Washington D C Ozone Hole
1,498 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 ...

3,718 wordsIntroduction Orbiting Ozone Layer Ozone Layer Introduction Orbiting above the Earth, an astronaut can look down on our home and see the thin blue ribbon that rims our planet. That transparent blanket our atmosphere makes life possible. It provides the air we breathe and regulates our global temperature. And it contains a special ingredient called ozone that filters deadly solar radiation. The Atmosphere The gaseous area surrounding the planet is divided into several spherical strata separated by...

Carbon Dioxide Ozone Layer
1,519 wordsIn environmental science the green house effect is a common term for the role water vapor; carbon dioxide and ozone play in keeping the earths surface warmer than it would normally be. The atmosphere is primarily transparent to infrared radiation from the sun, which is mostly absorbed by the earths 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 and remit a large pr...
