.... particles rising from the earth's molten core. As the plates are driven against each other one will try to and eventually will slip underneath the other. When plates move quickly an earthquake is the result. Before the availability of instruments capable of a quantitative measure of their magnitude, were classified according to their intensity. In 1931 a seismologist came up with twelve degrees of intensity ranging from I (felt only by a few) to XII (total damage) this was called a Modified Mercalli scale. However according to Dr. Pignataro "Even with such scales, the subjectivity of the observer renders their use less then .....

.... makes no difference. Scientists at CERN in Geneva are working on a device called the LEAR (low energy anti-proton ring) in an attempt to slow the velocity of the anti-protons to a billionth of their normal speeds. The slowing of the anti-protons and positrons, which normally travel at a velocity of that near the speed of light, is neccesary so that they have a chance of meeting and combining into anti-hydrogen.1 The problems with research in the field of anti-matter is that when the anti-matter elements touch matter elements they annihilate each other. The total combined mass of both elements a .....

.... rain. However, the most prevalent is the theory that electric generating plants, heating plants, and other industrial plants have been emitting an excess amount of sulfur oxides, nitrogen oxides, and volatile organic chemicals (VOC’s) into the atmosphere. Once these chemicals are in the air, they react with water to form acids and fall back to the earth as precipitation. People who believe acid rain is a natural phenomenon do so because of the fact that carbon dioxide in the air combines with water vapor and produces carbonic acid (Bolch 95). There are several environmental risks that come with acid rain. One of these is t .....

.... But, when taught to see and look for the warning signs of carbon monoxide, deaths in the home due to carbon monoxide poisoning can be prevented. Sometimes, in a home the hot water supply is low, or the furnace fails to keep the house warm. A natural reaction in any of these situations would be to turn up the tempeture on both appliances. But, did you know that a low supply of hot water, and a furnace that does not keep a house warm could be a warning sign of a CO problem ("More on CO" 97)? Additionally, by turning up the temperature on both units you just made a bad problem worse. Now each appliance is going to be ru .....

.... it to stimulate evaporation, then there was a smaller bulb that contained electrodes, simulating lightning and other static discharges, the evaporated water and gasses rose into this electrified bulb and were occasionally energized. The vapor then flowed into a condenser, and finally back into the simulated seas. The project was extremely simple, yet the results in a matter of weeks, was astonishing. The liquid turned the color of tea, and a black film formed on the inside of the “ocean” bulb. When the liquid and film was tested for its contents the transformation from simple compounds into highly developed molecules we .....

.... we can describe trace fossils in the Coconino and relate them to the physical environments of deposition. This provides us with more comprehensive reconstruction of the erg environments. Although the cliff-forming nature of the formation can present certain logical problems, the exceptional three-dimensional exposures in the Grand Canyon give the sedimentologist and ichnologist the opportunity to examine the details of one of the more classic and interesting eolian deposits on the Colorado Plateau. Lithology This layer averages about 260 million years old and is composed of pure quartz sand, which are basically pet .....

.... of Radiation. What does that mean? Basically a laser is a device which produces and then amplifies light waves and concentrates them into an intense penetrating beam. The principles of the laser (and it's cousin the maser) were established long before these devices were successfully developed. In 1916 Albert Einstein proposed stimulated emission, and other fundamental ideas were discussed by V.A. Fabrikant in 1940. These ideas, followed by decades of intensive development of microwave technology set the stage for the first maser (a laser made up of micro-waves), and this in turn helped to produce more advances in this area o .....

.... tropical air masses, in descending to earth, become hotter and drier. When a poleward shift in the west ocurrs, the high-pressure, anticyclonic conditions of the permanently arid regions hit each other on areas that are normally used to seasonally wet low-pressure weather and a drought follows. A southward shift in the western winds causes the most severe drought of the 20th century, the one that struck the African region, Sahel for 12 years starting in 1968. Statistics indicate that roughly every 22 years a major drought occurs in the United States, they affect the Prairie and midwestern states the most. The disastrous drought of .....

.... with the largest being the Great Barrier Reef covering over 2000 kilometers along the East Coast of Australia. The reef is said to be 500,000 to 2,500,000 years old and is said to be visible from the moon. There is only one problem with this beautiful structure and that is the carelessness of man. Silt from deforested lands and pollution from crowded coastlines choke them, and overuse by coal miners, fisheries, and even tourists deplete and destroy coral reefs. There are many more factors that add to the destruction of the coral reefs, which if not stopped it will destroy all coral reefs. Corals are animals, not plants; sunlight .....

.... change in the future. This model assumes the perfect cosmological principle. This principle says that the universe is the same everywhere on the large scale, at all times.2 It maintains the same average density of matter forever. There are observational evidences found that can prove the Big Bang model is more reasonable than the Steady State model. First, the redshifts of distant galaxies. Redshift is a Doppler effect which states that if a galaxy is moving away, the spectral line of that galaxy observed will have a shift to the red end. The faster the galaxy moves, the more shift it has. If the galaxy is moving closer, t .....
