    Study of the plate tectonics of New Zealand has been undertaken since the early 1800s, however the most notable discovery regarding the plate tectonic setting was made in the 1940s by Harold Wellman, who discovered the Alpine Fault. Since then, our knowledge of the plate tectonic setting of New Zealand has been vastly expanded, leading to our present day understanding of the topic. A large part of our present day knowledge of the plate tectonic setting has been gained through the study of active

    of Theia itself, the Earth’s crust has been formed, deformed, and even demolished. The crust has never been a completed masterpiece due to this. Why is this? The most recent physical changes were caused by the theory of plate tectonics and earth’s crust displacement. Plate tectonics and its movement resulted in our continents drifting across the earth’s surface, and the creation of mountain belts, volcanoes, and the faults of today’s Earth. A German meteorologist and explorer Alfred Wegener put forth

    A plate tectonic is defined as a solid rock mass that builds up the Earth’s surface. The plate tectonic theory is a theory that geologists use to help explain the surface processes and events. The word plate means large pieces of the earth that are always in motion, lithosphere plates. Tectonics means how the continents formed and move over time. This is the theory that most geologists accept as to what happened to our continents. It states that Earth is made up of two layers, the lithosphere

    Plate Tectonics Plate tectonics are a relatively new theory that has revolutionized the way geologists think about the Earth. According to the theory, the surface of the Earth is broken into large plates. The size and position of these plates change over time. The hypothesis of continental drift was largely developed by the German Alfred Wegener The edges of these plates, where they move against each other, are sites of intense geologic activity, such as earthquakes, volcanoes, and mountain

    The theory of plate tectonics was first developed by Alfred Wegener. He concluded that the continents seem to have a similar shape and could potentially fit together. This suggested that they were at one time joined together as part of 2 super continents called Gondwanaland and Laurasia was in the north. This theory was said to be proven by the discovery of fossilised remains of a mesosaurus that were found on the coasts of Brazil and Gabon. Sea floor spreading is another theory that supports the

    1.0 Topic Definition Plate Tectonics is a scientific theory which study how the Earth’s plates are driven and shaped by geological forces to keep them in constant movement. The theory explains the present-day tectonic behavior of the Earth, particularly the global distribution of mountain building, earthquake activity, and volcanism in a series of linear belt. (Pitman, W.C., 2007) Plate Tectonics explains geomagnetic and geothermal phenomena, magma and orogenesis, and it clarify the global mid-ocean

    Plate tectonics occur not only just on Earth, but on other planets in the galaxy as well, such as Venus, Mars, and ancient Mercury. Since there are several planets in the Milky Way that have plate tectonics, it is questionable about if size is a key factor in the likelihood of tectonics on foreign planets. Vol-canoes, mountains, ocean ridges, earthquakes, and tsunamis all would not be possible without the movement of the Earth’s tectonic plates. Dependent upon heat for movement, tectonic plates are

    According to the theory of plate tectonics there is constant motion in the lithosphere which causes the many plates lying upon it to move relatively to one another due to convection currents. There are 3 boundaries where volcanic and seismic events, but not limited to, occur. The constructive plate boundary is where 2 plates, such as the North American plate and the Eurasian plate move apart causing sea-floor spreading and volcanic activity – when the less dense basaltic lava from the asthenosphere

This type of plate boundary was the reason for the majority of the earthquakes documented over the semester. Most of these earthquakes were shallow, but at times had very deep focal points. Because of the old, cold plate being sub ducted I saw significantly more deep focus earthquakes in this tectonic setting. Subduction zones were also responsible for the deepest earthquakes that

Convection currents are thought to be the driving mechanism of plate movement. Convection currents cause convergent and divergent movements. When the rising part of the convection current rises it causes the upper mantle to move upward and in a lateral direction. This causes the mantle to split and new material to rise
