Abstract
This paper describes the continental drift and plate tectonic theories and traces their history, discusses the key players who were involved in developing the theories and examines the current state of scientific knowledge about Earth's geology and paleontology.
From the Paper
"The idea that the earth's continents have drifted has a long history. As long ago as 1596 the Dutch map maker Abraham Ortelius in his work Thesaurus Geographicus Ortelius suggested that the Americas were "torn away from Europe and Africa . . . by earthquakes and floods." He had been the first (and certainly not the last) to notice the apparent "jig-saw" fit of the bulge of eastern South America into the bight of Africa. (Kious and Tilling, 1999) In around 1850 A.D., a French scientist Antonio Snider-Pellegrini, while researching the similarity of the fossil plants and coal deposits in North American and European and concluded that the phenomenon could only be explained if the two continents had once been connected. In 1908 Frank B. Taylor of the United States invoked the notion of continental collision to explain the formation of some of the world's mountain ranges."

Abstract
The writer of this paper details the exploration of the ocean floor which began in the 1940s and aided scientists in developing the theory of plate tectonics. This paper explores how the work of researchers like Albert Wegener and James Hutton and the study of plate tectonics helped predict with some degree of accuracy where and when an earthquake will strike as well as predict which of the world's active volcanoes will erupt, saving countless lives.
Topics covered in this report include:

From the Paper
"Abraham Ortelius, a Dutch mapmaker, first suggested the possibility that the earth's landmasses were not fixed in 1520. He suggested that the Americas were once attached to Africa and Europe. They were then ripped apart by earthquakes and floods, creating three continents. It wasn't until the early part of this century, when a German meteorologist named Alfred L. Wegener became intrigued by this concept and the ideas set forth by other scientists that land bridges had been connected the continents at one time, but had then sunk into the ocean."

Abstract
This paper discusses how science has developed many theories of how the earth works to explain natural disasters and why they are a continuous part of human life. According to this paper, one such theory concerns the continental drift and plate tectonics that was explored to explain why certain natural formations upon the earth and in the seas are consistently changing.
From the Paper
"Redfern attempts, through his writing, to explain a concept of science that has been beneficial to humankind by exploring natural change sin the earth. Redfern contends that the concept behind the continental drift is that the earth is formed in large plates, which are massive sections beneath the surface. Redfern states that Continental crust is very different from the crust that floors the oceans. Ocean crust is predominantly magnesium silicate, whereas the continents contain higher proportions of aluminum silicates. They also contain less iron than the denser material of the mantle or of the ocean floor. "

From the Paper
"During the past century, considerable advances have been made in the field of geology. The discovery of plate tectonics has provided researchers with a unifying theory that explains many fundamental earth processes. Of the various hypotheses that led to plate tectonic theory, the most important was proposed by Alfred Wegener. Wegener's ideas on continental drift were supported by much evidence. However, perhaps because of its overwhelming implications, the theory was met with considerable resistance. Only in recent decades has scientific investigation collected sufficient evidence to definitively establish the validity of the continental drift hypothesis.
The theory of plate tectonics describes a lithosphere consisting of approximately the Earth's outer 100 kilometers.... "

Abstract
This paper help explains how Plate Tectonics has caused changes in continental landmasses through geological occurrences. It presents the main controversy in the Plate tectonic theory - whether the movement of the plates has displaced landmass across the continents or not and whether it is the sole reason for the change of the landmass or it is through atmospheric influence.
From the Paper
"Thousands of years ago the earth?s surface has been hypothesized as one big landmass. The Earth's surface has been constant motion. ?Fragmented into giant sheets of solid rock that glide atop a layer of hotter, more pliable material, the globe's appearance is forever changing.? [Cowen, 1999] . These plates are semi rigid, floated on flow of mantle. The plates measured around 50 miles, thickness of 25 miles on land and 4 miles thick under the oceans. Their movement was categorized by an average of a few inches a year. Even today, geologists and tectonicists hypothesize the earth to continue this movement in similar slow manner, even if we do not notice it. The plates? movement is called the Plate Tectonic Theory, a theory presented in 1912 but upheld in 1960 . "

Abstract
This paper takes a look at the tectonic plates effecting seismic activity in the state of California. The paper focuses on the Pacific plate and the North American plate, two adjacent plates moving in opposite directions, which form the San Andreas fault in California. The paper points out that plate tectonics play a major role in the various geological processes found in California, especially in relation to earthquakes and the San Andreas fault. The paper concludes that this plate tectonic activity has brought about much beauty and splendor, while also making the state a very dangerous and unpredictable place to live.
Table of Contents:
Introduction
The Geology of Plate Tectonics
The San Andreas Fault
Tectonic Activity in California
The Loma Prieta Earthquake
Conclusion
From the Paper
"One important part of the San Andreas fault is known as the Coachella Valley Segment and in June of 1992, the Landers earthquake, measuring 7.4 on the Richter scale, alerted geologists to the potential of a large-magnitude quake somewhere in the Los Angeles area. The Landers quake place much scientific focus on the clustering of quakes and tectonic activity close to the Coachella Valley segment of the fault. Thus, many geophysicists have been increasingly concerned with the high number of quakes and amount of tectonic movement occurring so close together on the northern end of the segment. In 1985, several geological investigators determined that a magnitude 7.5 earthquake along or on the Coachella segment could possibly trigger the so-called "Big One," yet if such a scenario occurred on the next segment north and west of the Coachella segment, the heavily-populated city of San Bernardino could experience massive destruction. In addition, a rupture of this segment could conceivably continue in line past Los Angeles and produce a quake measuring 8.0 on the Richter scale (Nance, 1988, p. 174)."

Abstract
This paper explains that plate tectonics is one of the most important discoveries in science and geology because it explains why the continents share many similarities, which could not be explained if they had always existed apart and it explains why, even today, the surface of the earth is constantly shifting, rearranging and moving. The author points out that an important discovery, which ultimately led scientists to believe the theory of plate tectonics was correct, was the discovery of seafloor spreading. The paper relates that plate tectonics and the continual shifting it produces can create many changes in the surface of the earth from weather to earthquakes and volcanic eruptions.
From the Paper
"Several theories of geologic process and scientific discovery helped lead to the discovery of plate tectonics in the 1920s, and the theory was generally accepted by the 1950s. The plate tectonic theory evolved from earlier theories, beginning with continental drift. The first time continental drift was mentioned was in 1908, by an American named Frank Bursey Taylor. However, the theory really did not gain acceptance until 1912 when German meteorologist and geophysicist Alfred Wegener detailed the theory and gave it more basis in fact. The continental drift theory believes that between 275 and 175 million years ago, all the continents were joined together in one land mass. Later, this massive continent broke apart into two gigantic landmasses in the north and south, those continents further divided about 100 million years ago into more currently recognizable shapes, and they began to drift apart during this time, too."

Abstract
This paper studies how plate tectonics and fault line movement are impacting the shape of the California coastline. The paper begins with a discussion of how plate tectonics have changed the earth's surface, including through earthquakes. Then the paper turns to one of the most famous major fault lines, the San Andreas fault. The paper examines its historical, current and future influence on California, such as the major earthquakes of the 1800s and 1900s. The paper concludes with a discussion of other fault lines, including active and inactive ones.
From the Paper
"Plate tectonics is responsible for the building of mountain ranges, the separation of continents through creation of new crust when the seafloor spreads as new lithospheric material pushes out of rifts on the ocean floor, and for earthquakes and volcanic activity (including the creation of volcanic islands and mountain ranges). The regions where the action of plate tectonics is most discernible is where adjoining tectonic plates are most active: pressing into each other, sliding over or under each other, sliding past each other. This activity usually takes place at a geologic pace--that is, so slowly that it escapes the notice of short-lived creatures such as human beings. Humans are unlikely to see mountain ranges forming or continents drifting apart. When two great tectonic plates, such as the Pacific Plate and the North American Plate, move relative to each other along the Pacific coast at an average rate of 2 inches a year, who would notice? But the these gigantic plates do not move only by drifting or creeping at such an imperceptible pace. As they mash into each other, portions of their adjoining edges get hung up or frozen in place for years at a time, even for centuries or thousands of years. The pressure on these junctures finally gives way as much larger movements which humans perceive (can hardly ignore!) as earthquakes."

"Plate Tectonics on Venus?
The plate tectonic theory is now widely accepted as a unifying basis for the physical geology of the earth as a whole. Not only does it explain most of the tectonic phenomena on Earth, but a number of key points have been well substantiated by paleomagnetic and seismologic studies (4). Venus, Earth's nearest neighbor, and similar in size, density, and age (8) might be expected to have similar tectonic activity. Indeed Soviet and U.S. explorations of Venus during the 60's and 70's revealed several features that could be interpreted as past or ongoing tectonism (Fig. 1). These included large calderas and arachnoids suggesting volcanism, dome uplifts, low ridge belts on planes, high mountain belts, heavily deformed areas called tesserae, and the circular coronae unique to Venus (9). Now that the..."

Abstract
This paper discusses tectonic plate movements and how they affect the surface of the earth by causing massive destruction produced by earthquakes, volcanoes and tsunamis.
From the Paper
"The global ramifications of tectonic plate movement is scrutinized by examining the damaging tectonic activity caused by earthquakes and volcanic eruption as well as the hazards these earthquakes in turn generate, namely volcanic eruptions and tsunamis. The damaging nature of these natural forces cause the world united grief as chilling images of vast wreckage are imbedded in their minds forever. These unstoppable tragedies remind us that we are insignificant in the greater scheme of life and we are still at the mercy of the throes of tectonic plate movement."

Abstract
The paper discusses myths and theories that have been disproved by science. The paper examines the theory of uniformitarianism. The paper explains that the idea is that the earth has been a very stable planet. The assignment looks at how new discoveries that have been proven eroded support for this theory and eventually continental drift has taken its place.
From the Paper
"Myths and theories are used by human cultures to make sense of the world. However, myths and theories can share a similar fate. This is because scientific investigation can disprove both myths and theories. This is made possible by the fact that science also provides a way to make sense of the world. One theory that seems to have been virtually destroyed by geologists is known as uniformitarianism. Uniformitarianism assumes that the earth and its continents are incredibly stable and almost never change (Benton 24)."

Abstract
The purpose of this work is to show whether or not Continental Illinois rescue and restructuring efforts were successful and if so, why. The paper also attempts to discover if the decision to restructure was justified and explains why or why not. Furthermore, this work attempts to discover to what extent did the OCC contribute to the management failing of Chairman and CEO, Mr. Roger E. Anderson and the management team of Continental Illinois and what short and long-term benefits were expected from appointing David Taylor as the new CEO and Edward Bottum as President in the run-up to the restructuring of Continental Illinois. Finally, the current status of Continental Illinois is is examined as well the main sectors of banking and how these sectors have changed since the collapse of Continental Illinois National Bank and Trust Company.
Introduction
Background and Overview of Continental
Results of the Method used by FDIC in the Rescue
Critics Opinion of the Open Bank Assistance
Summary and Conclusion
From the Paper
"Continental employed over 12,000 and held the approximate amount of $40 billion in assets. In May of 1984, at the time of near collapse the company had office in 14 states as well as 29 foreign countries with offices numbering 57. During the years 1976 and 1981 CCI experienced a jump in lending from $5 billion to over $14 billion with the company's total assets increasing from $21.5 billion to $45 billion with the loans-to-assets ration increasing from 57.9 percent to 68.8 percent between 1977 and 1981. The organizations return on assets stayed at 0.5 percent during the same time span and the return on equity was approximately 14.4 percent during those same years. (FDIC, 1997) The problems came under notice during 1982 when the Penn Square Bank, N.A. in Okalahoma City closed. The loans were underwritten poorly and it was clear that Continental had not used due diligence on the purchasing of the loans as well as Continental's loan portfolio beginning to experience problems specifically in the energy sector. It was reported by Continental in the second quarter of 1982 an amount of $1.3 billion in loans and assets that were 'nonperforming.'"

Abstract
This paper discusses the current status of The Continental Group, Inc., from strategic viewpoint. It focuses on each of Continental's divisions, financial services, energy, packaging, and forest products is examined vis-a-vis Continental's long-term growth and particularly its 5-year strategic outlook. The paper makes a final recommendation that Continental should sell its packaging and forest products divisions in order to finance the capital investments necessary for its financial services and energy divisions to grow.
From the Paper
"Strategic Planning--Continental Situational Overview The Continental Group, Inc. is a company that has been winnowed down to four primary divisions. These divisions form a corporation that is in desperate need of a corporate identity. While Continental has been somewhat successful managing its enterprises in the past, its seeming lack of a unified corporate vision will impede profitability and growth over the next decade unless a cohesive strategy is formulated and a corporate culture founded on a more unified business structure can be instilled in the corporation moving forward. Continental's 4 primary divisions at the present time are: * Financial Services: this division includes American Life Insurance Company which is a network of brokerage agents and representatives. It also contains a mortgage company, mortgage insurance, and real-estate related financial services. "
