.... can form many 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 th .....

.... longer occur. The first question one must ask is, "What is fusion?" One simple way of explaining it is taking two balls of clay and mashing them into one, creating a new, larger particle from the two. Now replace those balls of clay with sub-atomic particles, and when they meld, release an enormous amount of energy. This is fusion. There is currently three known variations of fusion: the proton-proton reaction (Figure 1.1), the carbon cycle (Figure 1.2), and the triple-alpha process (Figure 1.3). In the proton-proton reaction, a proton (the positively charg .....

.... Charcoal is used as a cooking fuel and ivory black, made by heating ivory, is used as a pigment in paint. Most carbon occurs in combination with other elements. For example, the carbon dioxide in the air is a compound of carbon and oxygen. Other compounds containing carbon include minerals such as limestone, and fuels such as coal and petroleum. Carbon compounds make up the living tissues of all animals and plants. There are over one million known carbon compounds (still growing rapidly every year), which is over the sum total of all the other .....

.... and upper atmosphere research was so great after World War II that by 1954 the possibility of launching a satellite was no longer in serious doubt. In October 1954 the Committee for the International Geophysical Year (IGY), announced to other countries that they were considering launching small satellite vehicles for space exploration. In April and again in July 1955 the USSR and the U.S. announced plans to launch for the IGY. The USSR launched SPUTNIK 1 on Oct. 4, 1957, and the United States launched EXPLORER 1 on Jan. 31, 1958. These two provided a lot of .....

.... the years. At the age of 18, he made a very important discovery about flustra, which is "1. That the ova of the Flustra possess organs of motion and 2. That the small black globular body hithero mistaken for the young Fucus lorious is in reality the ovum of the Pontobdella Muricata." (Rachels,7). In the early 1800's, a group of naturalists led by Captain FitzRoy, were planning an overseas trip, which they called the Voyage of the Beagle. They invited Darwin along, not as a naturalist, but as a helper. Through this trip, Darwin met many explorers that had .....

.... factors in an environment. It compares with droughts, floods, hurricanes and other physical disturbances because of the direct impact it makes on organisms. Unlike these physical factors, however, fire as a disturbing force is itself influenced by the biota, particularly the plant community. Alteration of the vegetation by any number of factors can influence the nature of a subsequent fire. Fire has similarities to grazing as a force on vegetation because of such feedback effects (Whelan, 1995, 20). Fire History When cavemen learned to make and use fire, th .....

.... attached to each other, and is usually white with no shading. Cirrocumulus appear like very small round balls or flakes. The cirrocumulus sometimes form a pattern of a buttermilk sky. The cirrostratus sometimes form tangled webs or thin whitish sheets. A large ring or halo is sometimes seen around the sun or moon when the cirrostratus covers the sky. The middle layer of range in altitude from 6,500 to 23,000 feet. The altocumulus, altostratus, and nimbostratus are found in the middle division. The altocumulus are more rounded and puffier than the cir .....
