    389 words
    Depletion of the Ozone Layer The issue of whether the people of the world have exaggerated the threat of the ozone depletion has been widely debated. It is an important issue because it concerns health and well being now and tomorrow. A variety of different arguments have been put forward about this issue. Because air pollution is greatly affecting the ozone, America needs to take immediate steps to stop ozone depletion. This essay will examine different arguments concerning the ozone layer. Oz...

    The source of the tropospheric ozone The tropospheric ozone has two major sources. One is intrusion from the stratosphere. Most of ozone in the atmosphere is in the stratosphere and created from solar UV radiation. The stratospheric ozone sometimes flows into the troposphere by the upper layer trough and cut-off low activities. Some part of ozone may subside in the troposphere directly by the Hadley circulation or the Brewer Dobson circulation. Another source is production from photochemical rea...

    The 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...

    The Importance of the Ozone " Like an infection that grows more and more virulent, the continent-size hole in Earth's ozone layer keeps getting bigger and bigger" (Beyond Discovery). The ozone is a protective layer that occurs naturally in the stratosphere, 6 to 28 miles in altitude. Each year, since the late 1970's, much of the ozone layer above Antarctica has disappeared, creating what is popularly known as the "ozone hole." This hole now measures about 9 million square miles, nearly the size ...

    THE SCIENCE OF OZONE Ozone, though similar to oxygen chemically, is composed of three molecules of oxygen and is usually blue in color with a very strong odor. The atmosphere contains less ozone than the common oxygen. While out of every ten million air molecules, there exist about two million molecules of normal oxygen and only three molecules of ozone. Most of these ozone molecules are typically concentrated in the Stratosphere, the atmospheric layer that runs roughly from ten km's to about fi...

    Triatomic oxygen, O 3, is most commonly known as ozone. It has a resonance structure, and can be drawn in two different ways: O = O- O-O = O It is a bluish, explosive gas at room temperature, and has a boiling point of -119? C. It has a melting point of -193? C, and is a blue liquid. It's critical temperature and pressure are -12. 1? C and 53. 8 atm, respectively. It has a pleasant odor in concentrations of less than 2 ppm, and is irritating and injurious in higher concentrations. The density o...

    The 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...

    Ozone, 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. Photochemica...

    The Ozone Layer Introduction The ozone layer is one of the most important source of protection that exists on Earth. It is a region of the stratosphere containing a high concentration of ozone, and it prevents a great amount of ultraviolet and other high-energy radiation from penetrating to the earth s surface. The ozone layer has been a security blanket that lies on top of the earth, protecting it from harmful rays, however, humans have abused of the use of CFCs, and other industrial chemicals ...

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...

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 ...

    Atmospheric 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...

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 ...

    The 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 o...

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 ...
