Plate tectonics

the tectonic movement or process involved The Christchurch earthquake in 2011 was a result of a transform boundary. Transform boundaries are when two separate plates slide past each other in their movement. During this process of movement, lithosphere is neither created nor destroyed. Many of these transform boundaries are found on the seafloor. This slide of plates can often lead to major earthquakes. In the central south island of New Zealand, consisting of Christchurch, much of the plate…

Alfred Wegener was a german scientist who developed the theory of Continental drift. He believed all the continents were one land mass. He called this super continent “Pangea”. Wegener used evidence from three sources to support his theory. First, was fossil evidence from reptiles and plants. “Cynognathus” was a reptile that had fossils found on South Africa, and Africa. This is only possible because of continental drift, the animal couldn't have swam across a whole ocean. The next reptile is…

deeper in how it really became to be interesting landform it is now. So let us begin this enchanted journey to how the Grand Canyon was formed. “Jones, Charles E.” states what the theory of tectonic plates is: “According to the theory of plate tectonics the outermost of the earth is made out of lithospheric plates, some 70 to…

Mid-Atlantic Ridge is in between the African Plate and South American Plate. It lies in between these two plates that are moving away from each other slowly. Although as a result of the separation of the two plates earthquakes occur and magma comes out making new crust. The magma comes out from a series of volcanoes that cool to make new crust. Crust closer to the rift is newer than the crust farther from the rift. The splitting of the African and South American Plate makes a divergent…

During the later stages of ore formation, Mn filled veins and veinlets of fractures and joints of the host rocks. The mineralized horizons (laminate and bands) are locally boudinaged and cut by the veins and veinlets, indicating that the role of tectonic activities and fault rupturing during the late stage of Mn mineralization in the area. However, emplacement of Eocene-Oligocene intrusions have also affected the ore bodies in the Venarch mine deposit and produced different alteration minerals…

American plates ("Magnitude 7.0 - HAITI REGION", n.d.). If there had been more warning of this earthquake, potentially thousands of lives could have been saved. There are predictions based on historical earthquakes that can help scientists warn potentially affected areas, but there needs to be a better communication of this information to the citizens of Haiti. Since a majority of the deaths occurred due to building collapse, there should also be an influx of building codes and materials…

greater than the length of the Grand Canyon. According to the www.livescience.com website The Mariana Trench was created by a process that occurs in a subduction zone where two parts of oceanic crust collide (subduction is a process when one tectonic plate collides with another and submerges under it slowly sinking…

and volcanoes although a majority of the tsunami is produced by earthquakes especially underwater earthquakes. [source 2] Earthquakes is the sudden rapid movement of the earth's ground that can be violent. It happens when the tectonics plate moves. Sometimes the plates don't move smoothly which allows pressure and tension to build and in the end it is the rapid release of energy that allows an earthquake to occurs.…

in this region. How are there even earthquakes in the middle of a plate? Most people know that earthquakes occur around plate boundaries, the places where the different tectonic plates of the world move past each other. But, there are also other regions within those plates called fault lines. These “lines” are areas where the Earth’s crust is significantly weaker than the areas around them. This results in an area within the plate with many more quakes than normal. eastern Canada, specifically…

of plate tectonic setting does the SAFS represent? The SAFS is a Transform plate boundary and the two plates are the North American and Pacific. And because it is a Transform boundary it means that the North American and Pacific plates move horizontally not vertically. F) How long ago did the SAFS first develop? Scientists believe that the SAFS is anywhere from 28 to 30 million years old. But in the southern part of the SAFS scientists say it around 12 million years old. G) What type of plate…
