Plate Tectonics Theory

Geological Features

Plate tectonics theory, which is the modern theory of the motions of Earth’s layer, explains how geological features, such as mountain ranges, continents, and bodies of water move and form. An important aspect of plate tectonics theory is that the outer layer of the earth is divided into plates which move across the earth’s surface. “These plates move relative to each other, typically at rates of 2-4 inches per year. As the plates move, they interact along their boundaries” (Plate Tectonics). In other words, the formation of geological features occur at the plate boundaries which is where plates slide and interact. There are four types of plate boundaries: divergent boundaries, convergent boundaries, transform

    Starting with the acceptance of the continental drift started the theory of plate tectonics. It is thought that plate motion produces mountains, ocean ridge systems, trenches, and other formations in earth’s surface. In the mantle, the solid metal in the core melts in the mantle which rises to the top. As the material cools as it reaches the outer mantle the plates move over for the other melted metal. The two plates move towards each other and one is sub ducted back into the mantle. This is how the plates move. The process of erosion is when materials are either:…

    Tectonic plate’s movement creates ocean basins, mid-ocean ridges, through collision. Colliding plates push sedimentary materials into an uplifted mass of rock that contains numerous folds and faults. The Earth has undergone a number of mountain building periods. The process of creation is first by the accumulation of sediments then the tectonic collision causes rock deformation and crystal uplift and finally the isocratic rebound continues to cause uplift despite erosion and causes the development of new mountain peaks through block faulting.…

    There are three plate boundaries, they are the divergent plate boundaries, transform plate boundaries and the convergent plate boundaries. Divergent plates move away from each other and are found in the middle of major oceans. These boundaries help to form underwater volcanoes and create new oceanic crust. Transform plates are plates that slide past each other and this is what causes earthquakes. If…

    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 extremely high. This decay can occur anywhere in the earth’s core. This results in a plume of magma rising through the mantle creating a thermal current. When this current reaches the surface it spreads through the asthenosphere, before cooling and sinking. These are the convection currents which move tectonic plates. Convection currents will only occur in liquid form and in warm conditions. Tectonic plate theory has evidence to prove that these currents do take place. We know that the mantle is liquid and has high temperatures as magma that originates in the mantle is molten. This means that convection currents can occur. This part of plate tectonic theory is supported by global seismic activity because if convection current did not exist and plates were not able to move, earthquakes would not occur at any plate boundaries, but particularly at collision plate boundaries as there would be no plate movement.…

    The global seismic and volcanic activity is concentrated along the margins of the earth’s plates, which are broken pieces of the crust and are moved by convection currents that are caused by heat rising and falling inside the mantle generated by radioactive decay in the core. This movement of the plates and the Earth’s inner activity is called plate tectonics and can cause seismic and volcanic activity. However, earthquakes and volcanoes also occur within the plates rather than their edges, an example of which is the Hawaiian volcanoes that occur above a stationary hot spot beneath the Pacific plate. In the late 1960s the theory of plate tectonics was developed by Alfred Wegener and provides an explanation for the Earths tectonic behaviour, particularly the global distribution of mountain building, earthquake activity, and volcanism in a series of linear belts. However, before the theory was developed people had noticed that the continents either side of the Atlantic Ocean seemed to nearly fit together. In 1912 Alfred Wegner published the theory of continental drift suggesting that the continents used to be joined together in an ancient supercontinent which he named Pangaea. He then proposed that it later split in to two continents- Laurasia in the north and Gondwanaland in the south, which further split forming our current continents and at some point these land masses had drifted apart to their current positions on the globe.…

    Natural destroys are a part of the nature of the world. There are many different kinds of natural destroys hurricanes, tornados, tropical storms, and earthquakes. The great state of California is no stranger to its part of natural destroyers. Many cities in the state have had its share having earthquakes. Earthquakes are produced by abrupt motion along a fault when friction that resists such motion is overcome by stress. Cities like San Francisco and Los Angeles have been known to have earthquake as well.…

    Plate tectonics have played a major role in the history of the Earth. All seven continents are where they are today due to the movement of plate tectonics. These seven continents were one big supercontinent called “Pangea” about 200 million years ago before breaking apart. The three different types of plate boundaries are convergent, divergent, and transform. These plate boundaries form due to the earth’s outer shell called the lithosphere having multiple plates moving around each other within the earth’s surface, allowing them to collide, separate, or slide past each other.…
