    The Ozone Layer The stratospheric ozone layer exists at altitudes between about 10 and 40km 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 a portion of the deadly ultraviolet (UV) rays from the sun. UV-A rays, including wavelengths between 320 and 400nm, are not affected by ozone. UV-C rays between 200 and 280nm, are absorbed by the other atmospheric constituents besides ozone

    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. Ozone is a highly

    ozone layer Summary of Learning of the Ozone Experience On the 16th of September 1987, negotiators meeting in Montreal finalized a landmark in international environmental diplomacy: the Montreal Protocol on Substances That Deplete the Ozone Layer. The Successful Conclusion of the negotiations in Montreal was widely hailed at the time as a historic even. As the protocol was the most ambitious attempt ever to combat environmental degradation on a global scale. In the 10 years since that meeting

    Ozone Layer Depletion Ozone is a natural trace component of the atmosphere. It is created continuously through the action of sunlight and oxygen in the upper atmosphere. At the same time this destroyed by various reactions with other components in the air. The next result of these natural processes is the so-called ozone layer in the stratosphere at altitudes between 15 and 50 kilometers in which the concentration of the ozone is raised. Ozone is a colorless gas, a form of oxygen

  • Depletion Of 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, 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

    Our Radiant Planet: Depletion of the Ozone Layer Ozone is a relatively unstable form of molecular oxygen containing three oxygen atoms produced when upper-atmosphere oxygen molecules are split by ultra violet light. Stratospheric ozone is found in a broad band, extending generally from 15 to 35km above the earth. Although the ozone layer is surprisingly thin, it acts as a protective shield to the earth, as it filters out most of the harmful solar ultraviolet radiation (in particular UV-B) that would

    THE OZONE LAYER: THE PAST, THE PRESENT, AND THE FUTURE The Past The ozonosphere or as we know it, the ozone layer, is the region of the Earth’s upper atmosphere. It contains a high concentration of ozone molecules. The ozone molecules in the ozone layer work to block an estimated 97-99 percentage of solar radiation from reaching the Earth’s surface. If the ozone layer were not present the radiation from the sun would kill most living things and make our planet uninhabitable. The size and thickness

    deteriorating of the ozone layer, the ozone layer is a layer of ozone (O3 gas) in the atmosphere that reflects most of the Sun’s UV-B radiation (radiation that is harmful to humans and all living things). Additionally, the Montreal Protocol, is an international agreement to protect the ozone layer from deteriorating chemicals, it has been signed by 197 countries to protect the ozone layer. There are also many Canadian initiatives that are in effect to protect the ozone layer. These initiatives have

    Holes in the Ozone Layer Ozone, 03 is a highly important component of the earth's atmosphere. Close to the ground ozone, is produced by the action of light on exhaust fumes and so concentrates in areas of heavy traffic. In this was it can be a pollutant, it corrodes metal, can inhibit plant growth and cause irritation to the lungs and throat. Up in the stratosphere though, about 15-50km above the earth surface, ozone is beneficial as it intercepts much of the suns UV (ultraviolet) radiation

    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 and
