Water Can Travel Shale And Sandstone Erosion
1,789 wordsWATER: IT MOVES THE WORLD Water does move the world, but not always in a noticeable or dramatic way. Erosion is a key element in making the world possible to live in. Erosion forms the valleys, literally dissolves solid rock, moves 3 ton boulders, and builds bridges. Water is the most abundant and therefore most powerful resource on the planet. Although water creates landmarks the size of the Grand Canyon, man cannot see the process, only the result. RAIN EROSION According to Rain Erosion: graph...

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....

The Ozone A Hole In Theory
2,357 wordsThe 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 crime of destroying the ozone. But...

Gram Positive And Negative Bacteria
828 wordsGram Positive and Gram Negative Bacteria It is a well-known fact that bacterial cells, like plant cells, are surrounded by a cell wall. However, few people know that their cell walls are quite different. Bacterial cell walls are made up of polysaccharide chains linked to amino acids. At the same time, plant cell walls are made up of cellulose, which contains no amino acids. In the same way, bacterial cell walls themselves differ from one another. Scientists distinguish two types of bacteria cell...

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...

Reduce The Amount Ozone Layer
1,136 wordsOzone derives from the greek word open which means to smell. It was first discovered in 1839 by Christian Friedrich 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, O 3 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, O 2. This is why ozone is harm...

Bright Pink Fruit Observing This Fruit Layer
1,700 wordsI am sitting at my desk with the fruit I ve chosen placed directly in front of me. I ve placed a pen and plenty of paper to right, which enables me to record all of my observations. Using all four of my senses (sight, touch, smell, and taste) as well as my thoughts throughout this exercise, I will try to make it clear what fruit I have chosen. Using just my sight I see that this fruit is almost a perfect sphere. It is about the same size as softball, but because of what looks like indentations a...

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 ...

Books New York Stratospheric Ozone
1,223 wordsChloroflourocarbons were discovered in the 1920 s by Thomas Midgley, an organic chemist at General Motors Corporation. He was looking for inert, non-toxic, non-flammable compounds with low boiling points that could be used as refrigerants. He found what he was looking for in the form of two compounds: dichlorodifluoromethane (CFC- 12) and trichloromonoflouromethane (CFC- 11). In both compounds, different amounts of chlorine and fluorine are combined with methane, which is a combination of carbon...
