  • Plate Tectonics - 883 Words
    Plate Tectonics First proposed by Alfred Wegener the meteorologist, the theory of continental drift supports the belief that the Earth's continents once were a single land mass. This land mass, which was named ‘Pangaea’, broke up, and its various parts drifted away from one another. Known as the Jigsaw fit, where countries fitted together but broke apart from Pangaea, shown by South America fitting into Africa. There is a lot of evidence that supports the theory, including paleomagnetism,...

    Plate Tectonics 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.

    Plate tectonics (from the Late Latin tectonicus, from the Greek: τεκτονικός "pertaining to building")[1] is a scientific theory that describes the large-scale motions of Earth's lithosphere. The model builds on the concepts of continental drift, developed during the first few decades of the 20th century. The geoscientific community accepted the theory after the concepts of seafloor spreading were developed in the late 1950s and early 1960s. The lithosphere is broken up into tectonic plates....

He claimed that all the continents were joined together at one point in time, and drifted apart gradually over millions of years. Wegener stated that continents are not rigidly fixed, but moving at one yard per century. Wegener published a book, The Origins of Continents and Oceans, which explained how billions of years ago the continents were once...

    1. Compare the age of igneous rock found near the mid-ocean ridge with that of igneous rock found farther away from the ridge. The ages of the igneous rock found near the mid-ocean ridge was younger than the igneous rock found farther away from the ridge. This is because of convection currents. Magma rises because it is less dense. It is forced out of the ridge, it spreads apart, and when it cools, it becomes new seafloor. This is why newer seafloor (igneous rock) is younger when it is...

    Subducting A subduction zone is formed at convergent boundaries by which an oceanic plate slides slowly under a continental plate into the Earth's mantle, as the result of pressure and friction. After a long period of time the overriding continental plate is lifted up creating a mountain range. This is how the Himalayas were formed. Sometimes the extreme heat and pressure exerted on the subducting oceanic plate causes an uplift of magma from the mantle which rises above the surface, creating a...

    Chapter One The theory of plate tectonics explains how forces within the planet create landforms. This theory views Earth’s crust as divided into more than a dozen, rigid, slow-moving plates. Some plates are as large as a quarter of the planet, but others are only a few hundred miles across. The plates slowly move across the upper mantle, usually less than an inch per year. Scientists use the theory of plate tectonics to explain the long history of Earth’s surface. They believe that about a...

    Volcanic and Seismic events are major pieces of evidence towards proving that plate tectonics theory is valid. A seismic event is the transient motion and release of kinetic energy caused by sudden failure of the earth's crust, usually felt as shaking or tremors in the rock mass. Seismic events range in size from barely perceptible tremors to major earthquakes. Volcanic events occur when there is a release of magma, gas and ash from the Earth’s crust.

    The initial theory of continental drift was put forward by a German meteorologist Alfred Wegener in 1915. This theory did not seem credible until it was connected with the plate tectonic theory in the mid 1960's. The Tectonic plate theory had an advantage over previous predictions as it could be supported by observed occurrences. One such thing that supports these two theories is that seen from space the continents look as if they might once have been joined together. This possible idea was...

    Constructive boundaries occur when two plates move apart which causes new oceanic crust to be formed and mid-ocean ridges are created by the build-up of molten rock on the seafloor due to the mantle building up. This new crust pushes the old crust aside and forcing the plates apart at a very slow rate. Basaltic lava rises which means new crust is being added continuously. Rift valleys are formed at constructive boundaries, where convection current causes the crust to be pulled apart causing...

    The theory of plate tectonics states that the Earth’s lithosphere is broken up into many different pieces separated by jagged cracks. These are called the tectonic plates. They are in slow, constant motion pushed by the convection currents in Earth’s asthenosphere. This theory explains the process of sea floor spreading at mid-ocean ridges, and subduction at deep ocean trenches. It was proposed by J. Tuzo Wilson in 1965.

  • Using Examples to Help You Explain and Describe the Processes and Features Found at Plate Boundaries to Show How They Support the Theory of Continental Drift and Subsequently Plate Tectonics.
    Continental drift is the idea that the earth’s continents are drifting away, relative to each other across the ocean bed suggested by Alfred Wegner as part of his wider theory on plate tectonics. The plate tectonic theory suggested by Alfred Wegner in 1915 was that millions of years ago all the continents were joined together in one mass of land called ‘Pangaea’, the evidence for this was that coal was found on Antarctica, the shape of Africa and south America fit together and same fossils...

    Volcanic and Seismic events are major pieces of evidence towards proving that plate tectonics theory is valid (40 marks) The theory of plate tectonics states that the Earth’s lithosphere (top layer of the Earth’s crust) is split up into rigid sections called plates that are moving relative to one another as they move on top of the underlying semi-molten mantle. These plates are either continental, The North American Plate, or oceanic, The Nazca Plate. Tectonic plates are powered by...

    Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events. Plate tectonics is a relatively new science. It’s partially explained in the sense that we still don’t know fully about how the plates came together, what they were before they were the seven continents we know today. We already know, or have a theory, about what our world was like a long time ago and so if we already know that the plates can pull and push against each other, then...

  • Discuss the Degree to Which the Theory of Plate Tectonics Is Supported by the Distribution of Seismic Activity Across the Globe.
    Plate tectonic theory is a widely excepted theory that the Earth’s lithosphere is made up of plates, both oceanic and continental, which slowly move due to convection currents in the mantle and the asthenosphere. However, it is very hard to be certain as we can’t see the structure of the Earth, so some people do not agree with it. This theory saw the introduction of what we know today to be tectonic plates. Tectonic plates occur where there is radioactive decay in the core and temperatures are...

  • How Does the Theory of Plate Tectonics Help to Explain the World Distribution of Earthquake and Volcanic Zones?
    How does the theory of plate tectonics help to explain the world distribution of earthquake and volcanic zones? The Earth’s crust is made up of seven major plates and several smaller plates. These plates drift on top of the mantle. When two plates meet, they can either be constructive, destructive or conservative. At a conservative plate margin, one plate moves past another. As the plates are not smooth, great amounts of tension build up and earthquakes are made when the tension is released...

    Introduction to Plate Tectonics via Google Earth Plate tectonics is a unifying framework for understanding the dynamic geology of the Earth. The theory posits that the outermost layers of the Earth (the crust and uppermost mantle) make up the brittle lithosphere of the Earth. The lithosphere is broken up into a number of thin plates, which move on top of the asthenosphere (middle mantle). The asthenosphere is solid, but flows plastically over geologic time scales. Plate interiors are...

    CONSERVATIVE PLATE MARGINS (TRANSFORM FAULTS): When two plates slide past each other they create a conservative plate margin. The relative movement is horizontal, and classified as either sinistral (moving to the left) or dextral (moving to the right). Along these margins crust (lithosphere) is not being destroyed by subduction, neither is it being created. There is no melting of rock, and, therefore, no volcanic activity or formation of new crust. Despite the absence of volcanic activity,...

  • Types of volcanism associated with plate margins
    Types of volcanism associated with plate margins There are two types of plate margin. When there is a boundary between two diverging tectonic plates, such as between the North American and Eurasian plates, it is known as a constructive plate margin. This is because it recognises the importance of magma rising up from the mantle to create new crustal rock. The boundary between two converging plates is known as a destructive plate margin, as it is responsible for more violent seismic activity,...

    Evaluate the strategies used to reduce the impact of tectonic hazards. Tectonic hazards are comprised of earthquakes and volcanoes; they are named ‘tectonic hazards’ as it is ultimately the movement of tectonic plates that cause these events. These hazards have the potential to kill thousands and devastate the region it strikes. Although the main hazard causes destruction, events that follow can be equally, if not more, devastating, for example an earthquake can often trigger a tsunami. Many...

At a sima and sima divergence such as the Eurasian Plate and the North American Plate, both crusts diverge leaving magma to rise up. This with aid from the cool ocean water solidifies and creates gentle sloping volcanos with basic basaltic lava with low viscosity. The type of volcanoes found at these margins are shield and fissure volcanoes. At this specific plate margin,...
