Ultraviolet Radiation Ozone Layer
1,027 wordsGreenhouse Effect On a bright, cool day, most people notice the sun's rays as feeling good on their skin. By nature, many of us even try to stay on the sunny side of the street while walking. The sun is 93 million miles away from earth and its energy travels to us in moving waves called radiation. The energy becomes heat, light and other energy too. Visible sunlight allows us to see the world around us, but there is invisible sunlight, too. These rays can't be seen, but some can be felt as heat....

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...

Low Birth Weight Nitrogen Dioxide
1,290 wordsAir Pollution Air pollution is one of the most dangerous problems of our times. Problems caused by pollution can be local and minor because of the Earth's own ability to absorb pollutants. The industrialization of society, the introduction of motorized vehicles, the explosion of the population are factors sharpening the growing air pollution problem. Carbon monoxide, nitrogen oxides and particulate matter belong to pollutants found in most urban areas. These pollutants are dispersed throughout t...

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...

Ozone Layer Ultraviolet Rays
962 wordsThe Problem The atmospheric ozone layer protects all living things from the harmful effects of the Sun. In recent years however, much damage has been caused to the ozone layer, causing it to decrease in size. The depletion of the ozone layer has and will continue to have many detrimental effects on all living things on this planet. A thinner layer will allow more of the suns ultraviolet radiation to reach the Earths surface. In particular, it will be the increase of UV-B rays which will have the...

Natural Greenhouse Effect Greenhouse Gases
1,722 wordsWhat is global warming, and how is it affecting the Earth and its inhabitants? Global Warming is sometimes referred to as the greenhouse effect. The greenhouse effect is the absorption of energy radiated from the Earths surface by carbon dioxide and other gases in the atmosphere, causing the atmosphere to become warmer. The greenhouse effect is what is causing the temperature on the Earth to rise, and creating many problems that will begin to occur in the coming decades. For the last 10, 000 yea...

Uv Radiation Ozone Depletion
993 wordsOur 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 35 km 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 ...

457 wordsThe Ozone Layer Ozone layer depletion slows There is good news about the ozone layer above us. The good news about the ozone layer is not always frequent. 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 o...

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 ...

Ozone Layer Ultraviolet Radiation
1,027 wordsOzone is an important molecule in maintaining the homeostasis in the environment. Ozone, the molecule O 3, makes a layer in the stratosphere, situated 10 to 15 kilometers from the earths surface. The dioxide molecule, O 2 and Oxygen atom O, collide with each other result in the formation of Ozone, O 3. In this reaction, the molecule O 3 contains an excess of energy. Once the molecule is formed, it is not stable enough to last long. The energy-rich O 3 molecules discards the excess energy by coll...

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...
