Plate Tectonics Theory
The story of Plate Tectonics is the story of continents drifting from place to place, breaking apart, colliding, and grinding against each other (Story pp). It is also the story of terrestrial mountain ranges rising up while being pushed together, of oceans opening and closing, of undersea mountain chains girdling the planet like seams on a baseball, and of violent earthquakes and fiery volcanoes (Story pp). Plate Tectonics describes the intricate design of a complex, living planet in a state of dynamic flux (Story pp).
Examination of the globe usually results in the observation that most of the continents seem to fit together like a puzzle (Plate pp). For example, the west African coastline appears to snuggle into the eat coast of South America and the Caribbean sea, and a similar fit appears across the Pacific (Plate pp). The fit is even more evident when the submerged…… [Read More]
Plate Tectonics and Landform Processes
The Aleutian Islands, Alaska
The Aleutian Islands are located along the southwestern coast of Alaska, ad at the northern edge of the Pacific plate. This plate runs along the Pacific coast of North America, with its well-known faults -- the San Andreas and the Denali -- causing the strike-slip plate motion that is familiar to residents of the Pacific coastal areas. However, at the Aleutian Island location -- a convergent boundary -- the strike-slip behavior changes to that of subduction. So, rather than the grinding of the North American plate and the Pacific plate against one another, at its northern edge, the Pacific plate drives under the North American plate. The 150 islands that make up the Aleutian arc create a sort of barrier between the Bering Sea to the north and the Pacific Ocean to the south. The Aleutian Islands are part of the…… [Read More]
plate tectonics is responsible for changing continental landmasses through geological occurrences.
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.

continental drift to the present to explain the plate tectonics theory and how the Earth is forever shifting. Use some examples of past and present changes in the earth and the effect they caused. A newer theory in geological history, plate tectonics is used to explain many geological changes in the Earth, both past and present, and indicates how the Earth is forever adjusting and shifting, creating uplifts and cracks in the many plates that make up the Earth's interior surface. These plates are the cause of earthquakes, and so, they are ultimately the cause of some of the world's worst disasters.
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…… [Read More]
Continental Drift and Plate Tectonics Theories
It is by now universally recognized that the continents and other land masses on the earth are constantly moving, albeit at a very slow rate and have been on the move for millions of years. The land masses have collided, broken apart and drifted across the planet while floating on the fiery mantle beneath the outer layer of its crust. The Continental Drift and Plate Tectonic theories indicate that about 250 million years ago there was only one continent on earth named Pangaea
This great land mass fragmented and its parts began to move away from one another forming the great oceans in between the continents. As an extension of these theories, it can now be predicted with a fair degree of confidence that the moving Continents will one day come together again to form a single giant land mass. This paper describes the…… [Read More]
d.). A researcher may determine if a rock sample is sedimentary by examining whether it consists of grains. An igneous (from the Latin word for fire) rock, known as granite, consists of minerals like quartz, mica, and feldspar. "Igneous rocks come from melted rock material, or magma, that lies under Earth's surface" ("How can you tell," n.d.), forming when magma from inside the Earth travels toward the Earth's surface, or a volcano forced it in the form of lava and ash above the Earth's surface, where it cools and crystallizes into rock. Metamorphic rocks, rocks, which may be sedimentary and igneous rocks, changed by intense heat or pressure while they form, come from hot, pressured conditions inside the Earth's crust. At times, these rocks cool and crystallize, into bands of crystals. A researcher may determine if a rock sample is metamorphic by examining the crystals to see if they are…… [Read More]
In addition to creating joints and faults, the stresses of tectonic plate movement can also result in other types of strain. This can make it initially more difficult to obtain clear information from a geological record, but ultimately reveals a great deal more about geological history than more easily discernible features. Two primary concepts upon which the science of geology are founded are ideas that layers of rock initially occur in "flat" layers, parallel to the Earth's surface, and that younger layers of rock remain closer to the surface unless otherwise disturbed (Alden 2010). This would produce a highly conformed geological record; the unconformities that exist in reality define the disturbances of geological history.
The most obvious and earliest discovered and described type of unconformity is the angular unconformity, in which the rocks below a certain level have hall been tilted in a similar direction and sheared off at…… [Read More]

Mathematicians Life and Works: Karl Gauss
There are many well-known mathematicians from history whose work is well-known and position widely recognised. However, there are also many lesser known mathematicians that have also made equally valuable contributions. Karl Friedrich Gauss is one of these, and as such is a worthwhile individual to study. Gauss developed many ideas and theories which are still in use today.
He is best known for his theory of plate tectonics and his work entitled "Theoria Motus Corporum Coelestium"; Theory of the Motion of Heavenly Bodies in 1809. With Wilhelm E.

As the mantle heats and cools unevenly, areas of differing density slowly move through the mantle. As they do, these areas of density variance have effects on surface features on the crust. For instance, there is a denser mass in the mantle shaped like a mushroom thousands of miles across and rising 900 miles from the Earth's core. The gentle rise of this mass has had the immediate effect of producing the African superswell, proof that motion in the mantle can have vertical as well as horizontal effects on the crust (Gurnis 40).
The lessons learned from the African superswell have been applied with great success in other parts of the world -- such as North American and Australia. The result has been a new understanding of the inner dynamics of the Earth. The motions of the mantle account for complex uplift situations throughout the world, and a deeper understanding…… [Read More]
The earth that we live in, from the scientific study, are formed from massive materials from millions of years ago. Scientists and geologists never stop the study of every inch of the earth's composition, but up to now, questions and debates brought up issues and fascinating stories of how the earth and its components were formed.
The history and evolution of the earth, its continents, and the bodies of water, are still yet to be proved. From the history of the solar system, the earth was formed from a large amount of rocky debris that fall together to form our planet. A massive material however crashed to the earth, melted its composition, solidified later, and formed crusts that created the earth's continents.
These crusts are unfathomable, too deep to enable scientists to conduct a study of what composes them and the various chemical processes that take place underneath the…… [Read More]
Both, ironically, are forms of pressure that also cause heat and changes. Water for instance, is so abundant on earth that it drives much of weathering and erosion. Precipitation, acidic soil water and groundwater dissolve mineral and rocks; serpentinization from heated seawater causes destruction of volcanic rock or changes in other seabed rocks; and the presence of water and carbon dioxide change rock as well. This is the manner in which the carbon and water cycle continually interact to change rock.
Plate tectonics, on the other hand, show that there are large scale motions within the earth that move, converge, and drive materials from deep inside the earth towards the surface and vice versa. Zones within the 8 or 9 major plates (subduction zones) form slabs of crust that become embedded and then if pressured enough with heat and more pressure, contribute to the evolution of rock. In addition, one…… [Read More]
Structural Geology and Plate Tectonics
This concerns the changes in the formation of the earth crust and mantle from the smallest to the largest, such as a series of mountains (UWYO, 2011). Conducting a study of these changes requires a conduct of fieldwork in coordination with other scientific disciplines, such as geophysics, geochemistry and petrology. The University of Wyoming has conducted such fieldwork on the different active and ancient areas of crustl and mantle changes. This fieldwork continues at present on topics, including continental and oceanic extensional tectonics, aboriginal arc-continental collisions, fault systems, crustal studies, fold and fault features and direct dating of these changes (UWYO).
These studies looked into the Archean depths in Wyoming province, the Rocky Mountain, the Alps, the Colorado River, the Carribean and the San Andres fault (UWYO, 2011). Researchers have swam and dug into thousands of meters into the ocean in order to look and…… [Read More]
At the American coastline, the estimated age is between 1 and 60 million years. Finally, at the borderline with the Philippine and the Australian Plates, the approximated age is somewhere between 160, up to 180, or even 200 million years.
6) the Atlantic Ocean plate is similar to that of the Pacific Ocean in the meaning that its age differs. Just like with the Pacific crust, the Atlantic crust is younger at one border, to grow older towards the middle of the ocean, and even older as it reaches the opposite border.
7) the spatial pattern of the crustal age is consistent with the theory of the plate tectonics, which argues that -- at one point in time (or even at several times) -- the entire lands on the planet were joined together (ockhounding Arkansas, 1998). The pattern of the crustal age is consistent with this theory as it reveals…… [Read More]

The inner core, meanwhile, has greater density, at 13, and temperature, at 6,650°C (or 12,000°F).
Compared against other planets in the solar system, the Earth contains just the appropriate amounts of gases, elements, and other properties that make human and other organism life possible.
Mercury, the planet closest to the Sun, has lesser mass and volume than the Earth, at a fraction of only 1/18. However, it is as dense as the Earth, although Mercury's surface is made up of more solid mass, specifically rough, porous, dark-colored rocks. Its atmosphere is made up of sodium and potassium, which accounts for the planet's density and very thin atmosphere. It was hypothesized that the core of Mercury is made up of liquid iron compound, as a result of the presence of magnetic field.
Venus, meanwhile, exhibits a unique characteristic for being the brightest and hottest planet in the sky, with the presence…… [Read More]
Leopold, Luna Bergere. Fluvial Processes in Geomorphology. Dover Publications, 1995.
Leopold's well-written and insightful book should be a required basic text for anyone interested in geomorphology. Specifically, the author delves into the basics of fluvial geomorphology, otherwise known as the study of the development of landforms under processes that are associated with running water.
Fluvial Processes in Geomorphology was originally written over 35 years ago, and does an amazing job of presenting the basic facts for fluvial geomorphologists. Over the years, a significant amount of additional detail has been added as the field of fluvial geomorphology has expanded.
Leopold's book consists of three main sections. The first part of the book centers on the process of change in the evolving landscape, and how geomorphology relates to field problems. The second part focuses on studies of climate, weather, flooding and erosion. The final third of the book centers on the processes…… [Read More]
Hamilton explains that while Continental Lithosphere is as much as 93 miles thick, the "Oceanic Lithosphere" is much thinner - up to perhaps six miles. Indeed, the oceanic crust makes up only 0.099% of earth's mass, according to Hamilton. Oceanic lithosphere is a product of the volcanic magma that pushes up to force tectonic plates aside. As new oceanic lithosphere is actually formed the heat that comes up with the magma "escapes the interior as this new lithosphere emerges from below" in the Red Sea and elsewhere where there are tectonic plates spreading.
As the lithosphere cools, it contracts and then "moves away from the ridge, traveling across the seafloor to subduction zones." This process is technically called "seafloor spreading." After the lithosphere has been on the Red Sea floor for a while, it thickens up, Hamilton writes, and as it becomes even denser than the mantle just below…… [Read More]
The physical geology of the earth consists of a Core (inner and outer), the mantle, the asthenosphere and the lithosphere. The lithosphere is the crust and upper mantle of the earth that is the hard and rigid layer in which humans live. This portion of the earth reacts to the atmosphere, hydrosphere and biosphere through erosion and weathering, resulting in the soil forming process (Johnson, 2006). These layers of the earth are constantly in motion, giving us the Plate Tectonics, or Continental Drift, theory. Briefly, the theory states that the continents move across the molten plate of the earth -- drifting over time based on the rotation of the earth. The early evidence for this, of course, was that the eastern part of South America and Western Part of Africa fit together quite well. However, studies after 1958 show that there are three major reasons why the "drift"…… [Read More]
The Mayans believed that a land called Mu once existed above the waves and that when that civilization fell below the surface, the survivors created the Mayan people (Hancock, Underworld: The Mysterious Origins of Civilization 73). In their creation story, the Mayans place Mu in the Pacific as a continent that pre-dates the Atlantis story. According to a translated Mayan Codec, the Land of Mu, like Atlantis, had been the center of significant social, scientific, religious, and cultural thought - it was, unlike Atlantis, an ideal place. When Mu fell during a massive geological upheaval, its people were able to escape to the continent of what is now South America and created the Mayan civilization - one of the most complex and significant of the ancient civilizations on the Americas.
Mu has been since taken up by what can only be loosely called New Age writers using it to link…… [Read More]
Alfred Lothar Wegener (1880-1930), German meteorologist, Arctic explorer and a brilliant interdisciplinary scientist, is best known as for his theory of "continental displacement" (that became famous, later, as the theory of continental drift). Since the technological means for proving the theory had not yet been developed and the idea was a radical departure from the scientific thinking of the time, Wegener's theory was widely rejected during his lifetime. After gradual accumulation of evidence in support of the idea, the theory finally gained acceptance in the early sixties. This paper gives a brief biography of Alfred Wegener, his theory of continental drift and other contributions to the world of science.

Igneous rock is one of the three main types of rock formations making up the earth's crust. It is formed primarily through the cooling and subsequent solidification of magma or lava. Igneous rock may also form without any crystallization -- below the surface as intrusive rocks or above as extrusive. It is best to think of igneous rock as being formed with heat -- one or more of three processes: temperature increases, decreases in pressure, or changes in composition. There are a number of types of igneous rocks; at least 700 have been cataloged, with most being formed deep within the earth's crust.
To describe the events that take place to move igneous rock from deep within the earth's core to the surface requires an understanding of the rock cycle. This is a concept that describes how rocks move and evolve into other types of rock or onto the surface…… [Read More]
ising From the Plains
John Mcphee, a writer of creative nonfiction books, started writing about the earth in 1985. He described the structure and movement of the earth's crust and mantle based on geology. He focused on the theory called plate tectonics which describes the earth's crust as several plates that bump with each other while gliding over the mantle. That theory was accepted only in the latter part of 1960's (decades after this idea was put forward for consideration), based upon geologic beliefs (Quammen, 1998). ising from the Plains is a good book in itself but can be seen as a sequel to his two earlier books namely In Suspect Terrainand Basin and ange. The book revolves around the ocky Mountains' geology and an adjacent terrain in Wyoming, both of which are near Interstate 80. The life story of David Love, a ocky Mountain geologist, and his household was…… [Read More]
The materials that are collected in them are solids from the various gases (which cooled inside these clouds). The gravity from the sun pulled them closer towards each other. This contributed to the formation of the planets and asteroids. ("Summary," 2007) (Williams, 2010)
Once a star is finished developing, is when solar winds will blow rock and debris away from the sun. This forms the Kuiper Belt and Oort Clouds, which is where the smaller debris is collected near the orbit of the outer body planets. These are the remains of the rubble that was used to create the solar system billions of years ago.
However, there is an exception to this pattern. In research that was conducted on distant galaxies, scientists discovered that there are not large outer planets with asteroid belts (i.e. Jupiter). This led to theories that much warmer Jupiter like bodies could exist closer to these…… [Read More]
The effects of liquids are not a factor in regional metamorphism as fluids cannot circulate due to the effects of pressure upon the rocks, which seal in the circulation of moisture. egional metamorphism occurs in areas of heavy tectonic activity, near the places where the earth's plates rub up against one another. "egional metamorphism can be subdivided into different pressure-temperature conditions based on observed sequences of mineral assemblages. It may include an extreme condition, where partial melting occurs" (Jessey & Tarman 2010). egional metamorphism is commonly found in mountain regions (hence the name regional metamorphism), consisting of foliated rocks developed under medium to high temperatures. "The accompanying pressures vary from low to high. Geothermal gradients, which are likewise moderate to high, produce Buchan and Barrovian Facies series. Because the pressures of Buchan and Barrovian Facies series are commonly higher than are those of Contact Facies Series, they may contain different…… [Read More]
The earth formed approximately 4.5 billion years ago. Our planet's geothermal heat originates from the energetic remnants of that coalescence. Over time, the interior of the earth "became differentiated into several distinct compositional zones: a large, iron rich core; a thick surrounding mantle; and at the surface, a thin, low density crust." (Montgomery 10). This fact contributed to a number of important attributes of the earth, including the formation of the atmosphere -- which came into existence thanks to gases escaping from the hot interior.
Despite the fact that the earth has been gradually cooling for the past 4 billion years, "The earth still retains enough internal heat to drive large-scale mountain-building processes, to produce volcanic eruptions, to make continents mobile, and indirectly to trigger earthquakes." (Montgomery 10).
A cross-section of the earth would reveal that it is surrounded by a thin outer crust that is about 10…… [Read More]
It wasn't until the 1920s and '30s that their blue-collar counterparts began to get paid vacations as well.
Americans in the late 20th century "worked more days per year than workers in other prosperous nations, such as those in Europe, yet on average, had less vacation time (Sabga, 2001)." Americans averaged two to three weeks off a year, in sharp contrast to many European nations which guaranteed up to six weeks a year. This is due to the fact "unlike in other countries, particularly Europe, vacations in the United States are not guaranteed by the government (Sabga, 2001)."

Metamorphic, Igneous, And Sedimentary Rocks and Their Application to Planets in the Solar System
The objective of this study is to examine metamorphic, igneous, and sedimentary rocks and their application to planets in the solar system.
There are reported to be three primary classes of rocks, which are classified according to their origination. The three rock types are metamorphic, igneous, and sedimentary rocks. Igneous rocks are formed when bodies of magma cool. As time passes and the rocks undergo process due to various weather cycles the igneous rocks erode and the particles and chemicals, which settle into beds, become compressed or cemented forming into what are known as sedimentary rocks. In the event igneous rocks are buried and then undergo a high state of heating and compression they form into what are known as metamorphic rocks. Eventually, the rocks undergo heat and compression and then melt with the molten rock…… [Read More]
These mountains surrounding the area have had an influence on much of the Great Valley's climate.
Particular to the valley is grassland which, in fact, has earned a name for itself and an advocate in this sense. Great Valley Grasslands State Park thrives on preserving whatever grassland is left in the region of San Joaquin Valley. The Valley allows for the nourishment of such wild flower as lupines, California Poppies, and Purple Owl Clover. Mountain runoff created wetlands habitats throughout the years, leading to the formation of marshes. Although they are not common anymore, they supplied the right environment for such trees as the Black illow, which is a water loving tree. Riparian oodland is also to be found in the Great Valley, as it is common to the Mojave Desert, however, their existence within the regions of the latter has been burdened by the tamarisk.

Naturalists and Materialists
Philosophy is credited to the Ancient Greeks. Historians, sociologists, and modern philosophers have traced the origins of philosophy to this period in history. The philosopher's position was as the community thinker, the people of the community who would sit around and think. Their jobs were to think about the best ways to improve society and to understand through thinking and concentration the principles of humanity. Philosophers attempted to use certain thoughts and concepts of understanding to come to some larger conclusion about the human condition as a whole. Socrates is argued to be the greatest of the philosophers and his way of thinking is believed to have shaped the ideas of centuries of philosophers to come. Before him, there were other great thinkers who, although they might not have had the same overreaching and lasting importance as Socrates, nonetheless contributed monumentally to the development of philosophical thought…… [Read More]
In the book The Greatest Shown on Earth: the Evidence for Evolution author Richard Dawkins (2009) attempts to explain how it is impossible for evolution to be logically denied if people look at the scientific evidence behind the theory. In the book, he in fact states that evolution should not still be considered as just a scientific theory. Rather, he believes that evolution should be considered an established fact regardless of people's religious teachings and subsequent beliefs. His attitude is one of an expert in the field who is talking down to those who do not agree with him, a perspective that makes his book believable but unlikely to convince people who do not agree with him on the subject.
In Dawkins' book, he uses many specific examples to further prove his assertion that evolution is far more than a theory, but proven fact. Among the many things that…… [Read More]
Hawaiian Volcanoes and Relationship to a Deep-Mantle Plume
From the many topics that were given as options by the facilitator of this class, the author of this report has chosen to write about Hawaiian volcanoes and their relationship to the deep-mantle plumes that are nearby and close to them. The area that has come to be known as Hawaii exists within a hotbed of volcanic activity. Of course, this is true both above ground and below it as well. Volcanos play a huge part in how the earth has taken on its current shape as many islands and even many continents have been greatly impacted or formed by the activity of volcanoes. hile the topic of this report makes it very clear that the deep-mantle plume and Hawaiian volcanoes are very heavily linked and this report will explore this in great detail using the suggested resources.

Planning and Reflection
During my student teaching experiences I kept a journal, which greatly helped me to organize my thoughts and clarify the areas in which I most needed to improve. My mentor also pointed out for me the key areas that need improvement. Therefore, as I look forward to a professional career as a teacher, I will be able to draw on these early experiences. I will remember what works and what doesn't and I already feel far more confident and proficient than I did before I undertook the student teaching challenge. In general a few major themes emerged through reviewing my journal entries and the statements written by my mentors. My strengths are my willingness to use a wide variety of teaching materials and teaching styles. An enthusiastic implementation of multimedia materials keeps students actively engaged, and keeps lessons more interesting. Moreover, my lessons are well-planned and incorporate…… [Read More]
Humanity might not have the same effective power over the environment when fossil fuels run out. While this assumption is certainly believable, humans will not doubt reach a point where the greenhouse gas absorbing plants and bodies will no longer be able to keep up with human activity. This will further exacerbate the problem of human-caused global climate change. On the other hand, if humans are able to develop non-fossil fuel alternatives that do not have a negative effect on the environment on a global scale, the warming trend might very well be reversed in a generation or two. Either way, Ruddiman's arguments will likely be proven to be wrong or right, on a long enough timeframe.

s a resident of Taiwan, I know all too well how devastating an earthquake can be. Japan and Taiwan both experienced earthquakes in March, 2011. The lives lost and physical damage sustained remind us of nature's power. Japan's earthquake continues to be major news because of the nuclear accident that resulted, the worst since Chernobyl. Taiwan's recent earthquake was, fortunately, far less dramatic, with damage to buildings and roads but no loss of life. Taiwan is frequently rattled by earthquakes, although they are usually minor. More than a decade ago, however, our island was rocked by a strong earthquake that killed more than 2,000 people. We wait and wonder if it will happen again.

MOISTURE-RELATED HABITAT PREFERENCES IN ISOPODS
PROJECT DESIGN PLAN
Isopods -- also known as "sowbugs" or "pillbugs" -- are usually mistakenly thought of as insects. In reality they are the only terrestrial species of crustacean, and are evolutionarily more related to crabs, shrimp and lobster than any kind of "bug."
This evolutionary relationship to so many aquatic species -- and the dearth of land crustaceans besides the isopods -- raises interesting questions about the isopod choice of habitat.
Crustaceans obviously have a system of underwater respiration using gills. Isopods also have these gills but do not live underwater: they are predominantly found in moist damp environments (beneath a rotting log).
But could isopods live underwater if necessary, or are their gills fully adapted to land life now?
I proposed an experiment to determine habitat preferences in isopods. It would offer a representative sampling of isopods…… [Read More]
