Ozone Depletion Ultraviolet Radiation
624 wordsIf all the ice in Antarctica melted, it would raise the level of the world's oceans by over 200 feet (60 meters). The possibility of this happening in the near term is not seriously considered by scientists, for the Antarctic icecap is currently believed to be in equilibrium. However, meteorologists studying the ramifications of global warming and the greenhouse effect expect there to be a decrease in sea levels in the short term -- a matter of decades -- of about 2 millimeters per year. This wi...

Funk And Wagnalls Carbon Dioxide
941 wordsCarbon dioxide lasers are one of the most powerful lasers ever constructed. The word LASER stands for Light Amplification by Stimulated Emission of Radiation. Lasers are devices that amplify light and produce light beams, ranging from infrared to ultraviolet. A light beam is consistent when its waves or photons, increase while mixing together. Laser light can be extremely intense, highly directional and very pure in color. Gas lasers such as the carbon dioxide laser is made active by ultraviolet...

Ultraviolet Radiation Nucleic Acid
1,499 words... these processes has the potential to damage the genetic material, and thus the cell. This in turn could cause cells to function poorly, causing premature aging associated with Werner syndrome. If the DNA damage happened to inactivate tumor suppressor genes or active oncogenes, it might also cause cells to grow out of control and produce cancerous tumors. In fact, there is already evidence that a faulty helicase can cause cancers. Recently a team led by geneticist James German of the New York...

High Blood Pressure Systemic Lupus
1,183 wordsLupus is a chronic, autoimmune disease which causes inflammation of various parts of the body, especially the skin, joints, blood and kidneys. The body's immune system normally makes proteins called antibodies to protect the body against viruses, bacteria and other foreign materials. These foreign materials are called ANTIGENS. In an autoimmune disorder such as Lupus, the immune system loses its ability to tell the difference between foreign substances (antigens) and its own cells and tissues. T...

Ozone Molecules Ozone Depletion
1,052 wordsThe beginning of the CFC (chlorofluorocarbons) era started in 1928, when CFC' were invented by a Du Pont chemist. CFC' were best known as "freon's" and became famous as a safe, nonflammable refrigerant. It's invention became a great triumph when Freon took the place of sulfur dioxide or ammonia which was used as the working liquid in refrigerators. It eventually became widely used in automobile air conditioners and nontoxic propellants in aerosol cans. It's insulating properties also was used fo...

Ultraviolet Rays Good Health
576 wordsThe eyes are described as the windows of the soul, the mouth as the courier of thought, and the nose as the servant of olfaction. The skin is just the frame to the picture. Unfortunately, many judge themselves according to this frame. They could either have feelings of content or censure of their own physical features. Good health and self-esteem go hand-in-hand during the process of exercising and establishing good health habits. The skin's clarity of acne, wrinkles, and sunburns is merely an a...

Greenhouse Gases Ultraviolet Radiation
421 wordsDiscovery of the hole in the ozone layer showed that human activity has a major impact on Earth. The destruction of ozone in the stratosphere high above the planets surface has been brought about as the result of the widespread use of chemicals, which under normal conditions are chemically inert and harmless. Ozone occurs at all levels in the atmosphere, but most of it is found in the stratosphere, between about 15 - 50 kilometres above the Earths surface. Even there it occurs in minute concentr...

I know that when I was younger it did not matter to me the importance of using an aerosol can of hair spray or a plastic pump non-aerosol hairspray. I figured that they were all the same. I feel that anyone without the education of the destruction would care either. It was not until I read about the evidence of our destruction that my ignorance of the ozone problem became too ...

Upper Atmosphere Ozone Layer
591 wordsOzone, pronounced OH Zone, is a form of oxygen that is present in the earths 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. Photochemical p...

Ultraviolet Rays Uv Rays
633 wordsThe ozone layer shields the earth from most of the harmful radiation and light comming from the sun. The ozone reflects and absorbs the ultraviolet rays that try to come in. Without this kind of protection, all living things will be effected by these UV rays. Skin cancer develops in most living mammals as a cause of an overabundance of the suns ultraviolet rays. The ozone layer is located in the earths stratosphere. The ozone layer is located from about fifteen-to-thirty kilometers above the ear...
