Myths And Legends Oxygen Atoms
878 wordsIn certain polar regions of the earth, a rare and fascinating phenomenon occurs in the dark season of winter. This phenomenon is called the Northern Lights, or auroras. In areas where auroras can be seen, the sun shines brightly for six months and then disappears for the next six. The sun follows a straight path across the sky, rising in the north and setting in the south. This is because of the latitude of these regions. Unlike other regions of earth, the polar regions either completely face th...

Polar Regions Magnetic Field
612 wordsPioneer 10 was launched in 1972 and flew within 81, 000 miles (130, 000 kilometers) of Jupiter on Dec. 3, 1973. The probe revealed the severe effects of Jupiter's radiation belt on spacecraft. Pioneer 10 also reported the amount of hydrogen and helium in the planet's atmosphere. In addition, the probe discovered that Jupiter has an enormous magnetosphere. Pioneer 10 was launched toward Jupiter on an Atlas rocket in 1972. After reaching the planet in late 1973, it made the first close-up photogra...

Plants And Animals Global Warming
709 wordsGlobal warming refers to the increase in average ground temperatures on earth. These higher temperatures across the planet are caused by an intensification of the greenhouse effect. Before recent scientific inquiries into this phenomenon, the greenhouse Effect simply referred to the natural process by which the earths atmosphere traps heat and warms the planet to a livable temperature. This heat trapping, however, has begun to escalate to possibly dangerous levels. Scientists have attributed thi...

Parts Per Million Chlorofluorocarbons Cfcs
3,718 wordsIntroduction Orbiting Ozone Layer Ozone Layer Introduction Orbiting above the Earth, an astronaut can look down on our home and see the thin blue ribbon that rims our planet. That transparent blanket our atmosphere makes life possible. It provides the air we breathe and regulates our global temperature. And it contains a special ingredient called ozone that filters deadly solar radiation. The Atmosphere The gaseous area surrounding the planet is divided into several spherical strata separated by...

Stratospheric Ozone Ozone Layer
2,496 wordsThe Atmospheric Ozone Layer The stratospheric ozone layer exists at altitudes between about 10 and 40 km 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 400 nm, are not affected by ozone. UV-C rays between 200 and 280 nm, are absorbed by the other atmospheric constituents besides...
