  • Stratospheric Ozone Hole
    2,448 words
    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...
  • Continent Size Hole In Earth's Ozone Layer
    843 words
    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 ...
  • Cfcs And Other Ozone
    4,117 words
    The Ozone a Hole in the Theory The protective ozone layer around our world undergoes much thought and debate. The 'Hole', however, only exists in the minds of environmental, self-serving scientists and politicians. It interests many to find all the faults in the publics consensus of the 'ozone depletion. ' Most scientists do not believe in this 'depletion', they think it is a natural phenomenon. Ozone gasses come into view as consideration over what gasses are actually accused for this awful cri...
  • Polar Stratosphere And Slow Ozone Destruction
    1,552 words
    The 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...
  • Greenhouse Effect And Ozone Depletion
    1,793 words
    The life in a greenhouse may be a deadly one in the future. Every single day people pollute the environment and the ozone layer cannot withstand all the pollution that takes place. Much of the pollution comes from cars, trucks, factories, and everyday house hold items, such as refrigerators and air conditioners. Holes start to form when the ozone gets to its thinnest point. When this happens, the greenhouse effect then starts up to haunt everyone. The greenhouse effect is the effects the sun has...
