.... You and all the things around you are made of matter. Since we all live at the surface of the earth where the acceleration of gravity is relatively constant, it has been natural for us to confuse the concepts of mass and weight. To study the difference, we need to separate these two "parameters." We could either leave the earth's gravitational field so that we would have no weight, or create an experimental situation where weight is not a factor. An easy way to do this is to use floating objects. Floating objects still have all their mass, and move almost friction-free in still water, .....

.... different and interesting shapes. At night the sky becomes enchanting and glorious. When the stars are out the sky is undeniably exquisite. The skys deep shades range from blue at dawn to deep oranges and purple at dusk. The sky scenes are genuinely picturesque. The forest changes it scenery in seasons instead of day and night like the sky. In the summer the forest is filled with majestic shades of green. The fall brings colorful shades of oranges, reds, and yellows. The winter deprives the forest of its colorful splendor, but brings a different type of beauty all together. In the spr .....

.... of SunLine Transit Agency in Southern California's Coachella Valley, is a firsthand proponent of alternative fueling. Having to smell the awful odor emitted day after day from his fleet of forty-seven buses, Cromwell (Silverstein 10) encourages the changeover. Phil Bostley, Mayor of Indian Wells, a subsection of Coachella Valley, agrees wholeheartedly by saying petroleum-base fuels will go the way of the buggy whips back in the 1930's (Silverstein 10). Fortunately, for those who run such fleets, a mandate issued by the Energy Department required operators to "begin purchasing alternati .....

.... of the South American continent. The jaguar is predominantly a forest dweller with the highest population densities centring on the lowland rain forests of the Amazon Basin - dry woodland and grassland also serve as suitable terrain, although the cat is rarely found in areas above 8000 feet. The overall body size and coloration of the cat often relates to its location - found in dense forested areas of the Amazon Basin are often only half the size of those found in more open terrain and it has been suggested that this can be related to the more frequent occurrence of larger prey species .....

.... no statistically significant pattern of improvement in dissolved oxygen levels in water in the last 15 years. It may be that we are only keeping up with the amount of pollution we are producing. (Knopman, 1993) The early biosphere was not pleasant for life because the atmosphere had low levels of oxygen. Photosynthetic bacteria consumed carbon dioxide and produced simple sugars and oxygen which created the oxygen abundant atmosphere in which more advanced life forms could develop. (Brown, 1994) The mystery of how Earth's oxygen levels rose is very complex. Scientists don't agree whe .....

.... from growth and development, as opposed to the local corporations. This is because MNCUs may not be as knowledgeable as local corporations in resource utilization and land management. This also refers to the notion of Rthe locals know their land better than anybody elseS. The tropical rain forest of Brazil is a good example of this. The RindigenousS or the local people have a good understanding of how to extract and utilize its resources in a very sustainable manner. However when a multinational timber company comes into Brazil, result of their actions will probably be more harmful, due .....

.... b. Whether the location is close to major transportation routes; c. Whether there is a suitable work force in the area for plant construction and operation; d. Whether there is sufficient energy resources readily available; e. Whether or not the chemical plant can carry out its operation without any unacceptable damage to the environment. Listed above are the basic deciding factors that govern the location of a plant. The following will explain in greater detail why these factors should be considered. 1) Raw Materia .....

.... of all atoms and carbon atoms weigh twelve times more than the hydrogen atom. Atoms that make up one alement are not like atoms that make up another element. These (atoms) are not simple particles, their structure is very complexe. They are, in fact, made up of smaller bits of matter called subatomic particles. An atom has two parts. Those two parts are; 1)at the center is a nucleus, a densely packed core composed of two kinds of paticles: protons and neutrons and 2)electrons. The charge in a nucleus of an atom is carried by a particle called a proton, the number of protons in an .....

.... Through guttation, tiny droplets of water are sometimes forced out of some plants. Guttation only works when soil is almost completely saturated with water and leaves are not losing much water through evaporation. When the xylem is full of water, the molecules will not move back down the structure, but rather need to be expelled from the plant. They will move, by the process of osmosis, to an areas where there is the least amount of pressure. These areas are usually openings located on plant leaves. Once the water molecules reach the leaves, the excess water will be forced out of the plant .....
