"Inland Playas
Many terms have been used to describe playas. In general, a playa is a closed body of water which occurs in a desert environment Playa salinity ranges from high to solute saturated--some lakes being completely ephemeral. In all playas evaporation will usually exceed input. These lakes are distinguished according to the presence or absence of groundwater influx. Dry playas are periodically flooded by surface waters and tend to be floored by silt and clay. When groundwater lies between 1 and 3 meters from the playa crust, capillary movement may form a puffy surface. When groundwater discharges into a basin it creates a moist playa. Moist playas are characterized by salt crystallization that tends to be deposited in outer carbonate zones, middle sulphate zones, and inner chloride zones. Present..."

"Coastal Process of the Great Lakes
The Great Lakes are a series of giant tubs linked by rivers and smaller lakes (Gorrie, 1988, p. 20). The flow starts in Lake Superior (the largest and deepest of the chain) and then passes through the St. Mary's River to Lake Huron and Lake Michigan (Gorrie, 1988, p. 20). Because these two are joined by the broad Straits of Mackinac, they behave as a single sea (Gorrie, 1988, p. 20). Their waters are connected to Lake Erie by the St. Clair River, Lake St. Clair and the Detroit River; the Niagara River connects Lake Erie with Lake Ontario (Gorrie, 1988, p. 20). Eventually, much of the Great Lakes' water egresses to the Atlantic Ocean through the St. Lawrence River (Gorrie, 1988, p. 20). In recent years, this system of waterways has attained some of the highest water levels recorded this century (Cobb, 1987 ...."

"Cirques
Glaciers are formed in areas where the annual accumulation of snow exceeds the amount melting or evaporating each year (4:80). This snow, under the pressure of its own weight, eventually turns to ice (4:80). When the ice becomes sufficiently thick, it begins to flow under the influence of gravity (4:80). Of the various types of glaciers, those found in mountainous areas show considerable variation in size (4:80.82). One of the smaller glacier types commonly found at higher elevations is known as a cirque glacier (4:79).
Cirque glaciers are characterized by the rocky hollows, or cirques, that contain them (4:80). The glacial ice tends to erode backwards and downwards forming a depression that accumulates snow (4:80). The formation of these glaciers is..."

"Destruction Caused by Miners in the 1800s
To say that the gold miners in California of the 1800s had a devastating impact on the land is a great understatement. As Robert Kelly says in his book, Gold vs Grain, "They tore up the underbrush, stripped off overburden, and even uprooted soaring pines in their search for gold.". The miners pitched camp anywhere and everywhere, never mindful of the precious and fragile environment which they encountered. All forms of their mining contributed to the destruction of woodland, including sluices, booming, placer mining, dredging, drift mining, mercury and chloride processing, and hydraulic mining. Even their sheep took a toll on the vegetation of California.
Droughts and floods increased because of miners' damage to the land. Miners would callously divert streams for their use ..."

"In the fall of 1987, a fairly large earthquake struck the Whittier Narrows fault in Southern California. The damage from that quake showed that the California State University at Los Angeles is located near the Whittier Narrows fault line (Kimball, 1988, p. 54). During that earthquake, a facade fell from a campus parking structure and crushed a young female student to death. In addition, severe structural damage was sustained in the university's library building. If another large earthquake were to hit the Whittier Narrows fault or any of the other surrounding faults, further damage and injury to human life could result. It is important that the staff and students at CSULA be prepared to deal with this type of emergency. One of the reasons for this importance is the fact that the university is a vital social and economic institution within the Los Angeles community."

"Solar Radiation and the Atmousphere
As the earth's nearest star, the sun determines much of what happens on the earth--its energy is what allows continued life on the earth, and its actions create the earth's weather, in the form of wind, clouds, and other climatic examples. The sun's warmth and energy are so important that without them the earth would become encased in ice (1:74). However, the earth is not completely open to solar radiation. The different layers of the earth's atmosphere provide different interactions (and different results from those interactions) with solar radiation.
The earth's atmosphere, the receiving end of the sun's radiation, is divided into four parts: the troposphere, which is the bottom-most layer and extends from the earth's surface to about 11 kilometers high (at which point the stratosphere..."

From the Paper
"The idea that the unique scourings of the earth along with the strange positionings of rocks found in Switzerland were a result of the Biblical Flood had long prevailed in science. It took a persuasive individual, highly respected in his profession, to finally turn that belief around, to realize that the real explanation was glaciation. The purpose of this paper will be to discuss the theory of glaciation in light of the contributions provided to the science by Louis Agassiz. The research will include a brief biography of the man as well as the impact he had on the concept of glaciation.
Jean Louis Rodolphe Agassiz was born in 1807 in Switzerland among the spectacular mountains that were to play a significant role in his life. Originally planning to become a physician, Agassiz' love of nature eventually redirected his training. By..."

From the Paper
"The Yosemite Valley is the product of many geological forces. One such is glacial scouring, which left the spectacular glaciated granite terrain that can be seen today. Valley glaciers have been described as "tongues of ice in mountain ranges [that] start in ice-worn rock basins called cirques". In these cirques, old snow develops into firn, or nev?, a "mass of ice pellets compacted by the weight of the snow above".
As more snow falls on the firn, it spills over into the valley below, filling it with ice. As this ice moves across the landscape, it collects rock debris, which polishes and scours the valley walls and floor. This scratching action leaves a definitive calling card in the form of grooves that identify ... "

"The ruby is one of the two stones categorized under the heading of corundum-- sapphire is the other. Ruby and sapphire may appear to be quite different but are in fact color varieties of the same mineral, chemically and physically the same, differing only in the amount of impurities they contain. It is in fact the chemical impurities that give them their value, for pure corundum is colorless. Corundum is a relatively abundant mineral. It is surpassed only by diamonds in hardness, so tons are mined each year to be used as an abrasive. The hardness contributes as well to the value of the gems consisting of this mineral. Corundum is composed of two light elements, aluminum and oxygen, and the close packing of these elements along with the strong bonding of the atoms are what give the gems their hardness and specific gravity. The ruby and the sapphire have long been prize ... "

"As the earth cooled from its molten beginnings, water seeped out of it and collected in the rough rock basins on its surface. The result vas the earth's ocean which has existed ever since as an integral part of life. No other planet in the solar system has such a body of water. The purpose of this paper will be to discuss the ocean as a key resource to human existence. Included in this will be a review of the various elements involved such as food, energy, oxygen and mineral wealth. In addition, the research will address the question of the ocean's survivability into the future as a result of human disregard for their environment.
While the earth is around 4.6 billion years old, the ocean has existed for about 2.5 billion years. Its total volume, which has maintained a steady state since its formation, ... "

"This paper will be concerned with earthquakes caused by the San Andreas Fault in the state of California. There are numerous earthquake fault systems to be found throughout California; however, the San Andreas Fault is by far the largest and "most conspicuous in the state".
Approximately 650 miles long, it is clearly the longest fault in the state. In addition, it is one of the deepest, dropping as far as 20 or 30 miles into the earth's crust at certain points. The San Andreas Fault varies widely in width throughout its stretch. In some sections, the fault is less than 100 yards wide. However, in other locations, the San Andreas Fault is "several hundred yards to a mile or more in width and is interlaced with any number of sub-parallel fault lines". The San Andreas Fault basically runs along the Coast Mountains which follow the ... "

"Thunderstorms are impressive and terrifying natural phenomena. Rattling the earth with sharp, explosive sounds of thunder, and lighting up the sky with electric bolts of lightning. As Mark Twain once said, "Thunder is good, thunder is impressive, but it's lightning that does the work."
Thunderstorms are defined in terms of their electrical manifestations which in fact are a product of the storm itself. The development of a thunderstorm is a continuous process but there are three recognizable stages through which the storm goes ((Hidore).
The first stage is the cumulus stage. During this stage cumulus clouds become larger and taller. There is a general updraft throughout the cloud formation and condensation in the form of water particles. The updrafts are strongest toward the (...)"

From the Paper
" The evidence of numerous ancient cultures suggests that gold played an important role in determining the course of history. Part of the reason why gold is so influential lies in its unique nature. Because of its purity, rarity and resistance to corrosion, it was commonly thought to be the ultimate metal and as a consequence became associated with eternity, divinity, royalty and wealth. Different civilizations used gold in a variety of ways to enhance their own existence. With gold, they adorned temples, built idols of their gods and monuments to their rulers and made jewelry and other decorative pieces for themselves. Throughout antiquity, it was the metal of choice for use by the rich, the powerful and the religious."
