  • Plate Tectonics

    The plate tectonic theory was developed in the 1960’s and it is extremely important to have a fond understanding of as it is an explanation of the amazing scientific feats that have happened and are still happening in our world today. For example, it explains why the land we stand on is in its place, how volcanoes, tsunamis and mountains are formed and many more scientific phenomenon. This theory is that the outer shell of Earth is separated into multiple plates, which are floating on the mantle, the Earth’s liquid inner layer made of semi-molten rock which we call magma. The magma is hot and the temperature causes great pressure onto the outer layer of Earth. The force that causes the plates to move is called convection, a process in which hot magma rises toward the surface of the plates and as it cools, spreads and new magma from the bottom, rises to the surface as the cooling magma descends, “Just like a pot boiling on a stove” (Van der Elst). Convection is the cause of the movement of the plates, and there are three different types of boundary movements. Firstly, converging movement, which is a destructive process where the plates collide; secondly, diverging or spreading, where land is created by the plates spreading and finally, transforming movement a process in which no land is formed…

  • Pange Plate Tectonics

    movements of our continents is called Continental Drift. This theory is supported by plate tectonics, a relatively new idea that explains the constant movement of Earth's crust. Two-hundred million years ago, our seven continents fitted together, as if part of a puzzle. These continents made up one supercontinent, known as Pangea. When Pangea began to disperse into the current continental positions the process of plate tectonics began. The first to notice the fitting of the continents was…

  • Plate Tectonic Analysis

    The earth was not only cracked but it appeared to be cracked in pieces scientist call these pieces tectonic plates when scientist realized that the earth was broken into plates they finally had enough evidence to explain how it was that continents could move. The theory that explains plate movement is called plate tectonics. To understand more about plate tectonics and continental drift we have to look deep inside the earth the earths interior consist of several different layers the inner core…

  • Plate Tectonics Essay

    Plate tectonics is the belief the lithosphere is separated into a few dozen plates that move around across the earth 's surface relative to each other, like big pieces of ice on a lake. If we were able to lay the earth flat to see where the plates were positioned, it would have the appearance of an orange peel; with the earth 's crust as the orange color shell and the white as the lithosphere. The break points would be fault lines, the plate’s outer perimeter that aligns and intersects them.…

  • The Effect Of Plate Tectonics On Venus

    I believe that there are no plate tectonics on Venus. I believe this because of the reasearch that i did on this topic. Venus shows no evidence of plate tectonics on it's planet. " There are no long, linear volcano chains or any clear subduction zones. The transform plate boundary, causes the plates to slide past one another, which may cause earthquakes or fault lines, which is exactly what is happening. The plates are sliding past one another and earthquakes ar occuring which may lead one to…

  • Pangae The Evolution Of Plate Tectonics

    present positions. Although others brought fourth evidence, plate tectonics processes and continental drift was not of interest until the late 1950s, when scientists discovered the alignment of magnetic particles and traced them to the earth's magnetic field of that time. According to studies of paleomagnestism, once the paleomagnetic polar changes were plotted, it brought up conspiracy that all continents had shifted…

  • Catastrophist's Theory Of Plate Tectonics

    Geology The Field of Geology didn’t become a major field until World war II, when the sea floor was mapped out in detail for submarines revealing a mid-Atlantic underwater mountain range, and a rift which started the theory of Plate Tectonics. Plate tectonics are used to explain the forming of mountains and even continents after the Pangaea. Plate tectonics explains that continents could have broken up, but there are 2 major theories on how. Catastrophist’s believe that a series of catastrophes…

  • The Pros And Cons Of Plate Tectonics

    Geologically, we can divide the outer core of the earth into two parts which are lithosphere and asthenosphere. Lithospheric shell contains a number of major breaks which can be referred as plate boundaries. Lithosphere sits on Asthenosphere, which is the portion of the mantle, causing the plates to move around as its solid and ductile properties. When we think about the movements of plate tectonics, we generally come up with the idea of dramatic natural disasters which destroy and derive…

  • Plate Tectonics: Understanding The Layers Of The Earth

    layer, the crust, is made out of plate tectonics. All the different phenomena that we see on Earth, such as earthquakes, volcanoes, and landforms, are caused by the plate tectonics. In order to understand the layers of the earth one has to understand how the earth was formed. Earth started out as planetesimals, small bodies from which a planet originated in early stages of formation of the solar system, colliding together and the force of gravity creating protoplanets. The…

  • The Pacific And North American Plate Tectonic

    Plate tectonics is a theory about how the plates are constantly moving on top of a layer of magma that is constantly taking in old crust to recycle it this constant movement causes earthquakes, tsunamis and other geological events. The movement of the Pacific and North American plates cause the old sea floor to be replaced by the now wider North American plate. Also with the movement the continental plate was stretched as the Pacific plate pulled the continental plate to the northwest which…
