  • Depletion Of The Ozone Layer - 1,052 words
    Depletion of the Ozone Layer Depletion of the Ozone Layer CHEM 151 Research Paper July 11, 1996 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, Crutzen 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 "global biogeochemical cycles" as well as the effects of supersonic transport aircraft that release nitr ...

  • Global Warming - 1,544 words
    Global Warming (After a lot of reading and hunting around on the net, I found a great deal of information on this topic. I had never really researched on it before so wanted to make sure that calculations agreed from report to report. Most of them did so I will base my answer on these different reports. This subject is extremely interesting, scary and a bit of a shock as to how much we have abused and taken advantage of this Earth. Though progress as far as technology has been something we make use of and enjoy, we are paying for it in ways I never thought of before this subject came up in this class! Please forgive my ignorance. I am troubled that my children and their children will suffer ...

  • Ozone - 983 words
    Ozone annon Ozone is an important molecule in maintaining the homeostasis in the environment. Ozone, the molecule O3, makes a layer in the stratosphere, situated 10 to 15 kilometers from the earth's surface. The dioxide molecule, O2 and Oxygen atom O, collide with each other result in the formation of Ozone, O3. In this reaction, the molecule O3 contains an excess of energy. Once the molecule is formed, it is not stable enough to last long. The energy-rich O3 molecules discards the excess energy by colliding with another atom or molecule and transferring the energy in the form of heat. In the results of the decomposition of ozone into O2 and O in the ozone layer, solar radiation is absorbed. ...

  • Ozone Layer - 1,860 words
    Ozone Layer Some scientists have proclaimed that the human race is slowly depleting the layer of ozone which protects us from ultra violet light. In reality, humans have very little control of the world in which we live. Scientific evidence has shown that there is very little depletion in the ozone layer and the contributions the human race makes towards this depletion is and always will be insignificant compared to nature. The theories of the depletion and what it would cause are flawed and contradictory. Where and when did this global killing threat begin? It all began in the mid 1960's when the United States government began pursuing super sonic transports. These would be planes which wou ...

    ... ne hole is firmly established to be halogen chemistry....There is not a full accounting of the observed downward trend in global ozone . Plausible mechanisms include heterogeneous chemistry on sulfate aerosols [which convert reservoir chlorine to active chlorine - R.P.] and the transport of chemically perturbed polar air to middle latitudes. Although other mechanisms cannot be ruled out, those involving the catalytic destruction of ozone by chlorine and bromine appear to be largely responsible for the ozone loss and are the only ones for which direct evidence exists .

  • The Ozone - 1,107 words
    The Ozone The Ozone Ozone derives from the greek word ozein which means to smell. It was first discovered in 1839 by Christian Friedrick Schonbein who noticed it because of its distinctive acrid smell. He discovered this at the University of Basel in Switzerland. Ozone is merely oxygen, but not the type we breath. Ozone, O3 has three compounds while oxygen has only two. Ozone is reac- tive, meaning it does not stay still, and wants to go back to its original state, with two compounds, O2. This is why ozone isharmful. Ozone always wants to let go of its third compound, and if this compound reacts with other substances, it could be damaging, especially to humans. When discussing with the ozone ...

  • Wildlife - 871 words
    Wildlife The"cry of the wild" can still be heard across this great land. I have heard the bugle of an elk on the Great Plains...the shrill of a bald eagle along the banks of the mightily Mississippi...the roar of a brown eagle bear on windswept tundra...and the gobble of a wild turkey among western foothills. Amazing beauty can still be found in the natural landscapes of this great land. I have seen through televisions, articles, books, and newspapers the towering forests...pristine waters...rich wetlands...wide-open prairies...majestic mountains...and vast deserts alive with color. I am in awe by the complexity and wonder of the natural world. Truly, it is where you can find solace and peac ...
