Geology Overview Using the topics provided in the course syllabus, I came up with three categories in total. My first category is “Basics of Geology” which includes:
• What is Geology?
• Plate Tectonics
• Inside the Earth
• How Mountains Are Made
I chose these specific topics because I felt that they all fell under the common theme of general/basic mechanisms and encompasses main theories and processes of Geology. In order to understand the former three topics, you must understand what Geology is. Plate tectonics is the “Big Idea” for Geology, a key theory that Geology is based on. You must also understand why plate tectonics are possible (because of the rock flow inside the earth) and its effects, which include how mountains are made. My
The three topics I picked are gender, race, and religion. However, my views on these subjects have not changed because I considered myself to be a very open-minded person. After reading "The Berdache Tradition" I learned that the several Native American tribes had a different kind of cultural construction of gender within their group. I was very fond of their origin myth that was about several worlds and crossing over them to find equal ground for everyone. I found this reading to be very interesting because it seems that no one takes the chance to mention the subject of having more than one gender. Usually people are focused on physical differences of sex and the expectations that are associated with gender. The same goes for the group in
It is really interesting to break down the separate classes and find their similar details and their different details. Obviously the differences are greater in number and some of them fairly extreme. But that is to be expected.
Earthquakes are caused by tectonic plates moving in the earth's crust. They either move apart or pull together at faults. Two forms of faults are normal faulting where the hanging wall moves downward causing rocks to be pulled apart by tension and reverse faulting, which is the opposite where the hanging wall moves upward casuing rocks to be forced together by tension. These movements cause tectonic plate boundaries called divergent boundaries, convergent boundaries and transform boundaries. Each boundary is different and play a
In conclusion table 10-1 on page 292 list the three types of models. These models provide
...oncerning the way people live and interact in America today. From why California has so many earthquakes with the San Andreas Fault, to the formation of America’s national treasure Yellowstone Park, and even why certain crops are located where they are, it is important to know just how geology affects the United States. There are many different ways how America has changed throughout time, but the evolution in geology is the changing face of America.

Since the beginning of human kind there has been a cloud of wonder of how our planet was formed. Scientist interested in this field through out the years have developed many different theories to how our planet came about. Before the Twentieth Century, scientists and geologists thought that mountain structures were due to the massive tightening of the earth caused by the gradual cooling of molten rocks. In 1900, American scientist Joseph Le Conte, published an article in the Appleton's Popular Scientific Monthly. He described that the problem in understanding mountain building was establishing the cause of sideways pressure. It was not until 1910, that an American Geologist named F.B.Taylor, proposed the idea of a continental drift. Other scientists dismissed Taylor's idea, because there was just not enough proof. However, Taylor's idea was then backed up by a German scientist named Alfred Wegener. He proposed that the continents surrounding the Atlantic Ocean, Africa and South America fit together like a jigsaw puzzle. His broad range of studies enabled him to incorporate his theory of Plate Tectonics. Wegener, later in 1915 while in the German military published his idea that interpreted how his continental drift theory worked. He proposed that a huge landmass called Pangea, meaning ("all land") existed 200 million years ago. He furthered explained that this super continent began to drift apart very slowly throughout millions of years into what it looks like now. Wegener went on several expeditions through out his life to the continents of South America and Africa.
First you might need to know definition of tectonics. It is a theory in geology. The lithosphere of the Earth is divided into a small number of plates which float on and travel independently over the mantle and much of the Earth’s seismic activity occurs at the boundaries of these plates. That is the official definition of Plate tectonics. secondly, this plate covers many parts of continents. plate boundaries don’t go according to Continents boundaries, they make their own boundaries. The North American plat...

Ever since the beginning on time, Humans believed the ground is solid and immobile. But this is not true whatsoever. The Earth is every-changing and continually in motion. The stability of the Earth is not at all what we think it is. Thinking about the rotational axis of the Earth, and possibly of what the Earth may become at a certain point in time, has a great influence on understanding all aspects of living things, either in the past, present, or future. The Theory of Plate tectonics is accredited to most of the creations of Mountain Ranges, the Centennial drifting Theory, for earthquakes, and volcanic activity. Plate tectonics and mountains also play a big part in the Earth and its geological features.
Tectonic Plates are what cause many of earths natural disasters. These can come in forms such as volcanoes, earthquakes and tsunamis. The earthquake of San Francisco was one of the most devastating earthquakes in the earths history and had ended in tragedy (Quinton et al, 2012, p189). These tectonic plates also resulted in the change of earths continents. More than 200 million years ago, all of Earth’s continents were combined into one super continent called Pangea. This continent slowly separated into 7 others we know of today (Quinton et al, 2012, p176). There are many known theories to why the Earth’s continents have changed overtime, such as the Continental Drift and Seafloor Spreading theories. These two theories help to explain the worlds creation, one of the most unknown mysteries of today.
Earthquakes are sudden, violent shakings in the ground that is caused by the movement of the Earth’s crust or volcanoes. More than 10,000 earthquakes take place every year, most of them not recognized by humans. Earthquakes do not occur at random locations, however, as some people believe. A pattern can be seen where most earthquakes occur at or near the plate boundaries. In fact, these earthquakes are what help scientists discover where these plate boundaries are. Plate boundaries are the cracks between the set of tectonic plates that make up the Earth’s crust. The moving of these tectonic plates is what causes these earthquakes. There are three types of plate boundaries: divergent boundaries, convergent boundaries, and transform boundaries.
Plate tectonics is a theory in earth science about plates that ride on the asthenosphere. These plate tectonics carry continents and ocean basins. There are seven major plate tectonic plates and many minor plates. There are two types of tectonic plates: oceanic and continental plates; continental plates have a density of 2.7 g/cm^3 but oceanic plates have a density of 3 g/cm^3.The area at which these plates meet are called plate boundaries. There are three types of plates boundaries that we have identified: convergent plate boundary, divergent plate boundary, and transform plate boundary.
I will begin this paper by reciting some of the definitions that I did find.
First order relief features are tectonic plates and are the largest in special extent. Two types of plates; continental plates and Oceanic plates. These are differentiated by their rock and mineral composition. Continental plates are lighter in density and are composed of granitic rock materials rich in silica and aluminum. The oceanic plates are made up of dense, basaltic rock composed of silica and magnesium.
