The Pros And Cons Of Active Plate Tectonism

Improved Essays
The continuous movement of the heated substances in the planet’s interior causes tectonism to proceed, and some planets in modernity still have active tectonism, such as Mars, Earth and Venus. Planets that are miniscule are found to cool off quicker due to to the proportion of volume to area, which causes smaller planets to desist to have plate tectonics faster than larger planets. The absence or presence of tectonism on a planet circumducts around the capacity of the planet and the amount of water on the planet. The outer planetary layer is limited of heat due to the brittle deformation caused by liquids, and can further expand the knowledge on the mechanics of rocks.

Tectonism is the moving and deformity of the exterior layer of a planet

After taking photos of Venus on a spacecraft called the Magellan in 1979 (Kerr, 1992), low-resolution photo-graphs of the planet have caused researchers to determine that Venus has indeed gone through the proposition of active plate tectonics by confirmation of newly formed crust on the planet compared to the trenches of the ocean bottom on planet Earth. These images were compared to the crust of planet Earth after an emasculated submarine called GLORIA that uses sonar radiation to examine the seafloor correlated to how Magellan traced the ridges on Venus. Photographs of the plates on both Earth and Venus have been determined to angle upwards on one side while the other side curves down into the mantles of the planets, exemplifying how the plate tectonics of both planets appear to be similar. Even though the plates on Venus were thought to be thinner than the tectonic plates of planet Earth, the bulges in the plates have implied that Venus’ plates are estimated to be around 40 to 50 kilometers thick, just as on Earth (Kerr, 1992). This further demonstrates how the internal structures of Earth and Venus share similarities in how their planets manage …show more content…
The relation be-tween size and planets influence that the likeliness of plate tectonics increases with increasing planet size, usually with in-creasing density to also be a factor. Scientists such as (Heck and Tackley, 2011) agree that although the data they gathered seemed reliable and correct, further care should have been put into interpreting the values of friction coefficients and yield stresses, because the values are dependent on the overall conclusion of the tectonic behavior. Other scientists have come to conclusion that Venus and super-Earths have encountered tectonism in antiquity (Valencia et al.,

    Trans-Pecos Province Magma Types Nathanial Matis 01/12/2014 Trans-Pecos Province Magma Types Nathanial Matis Abstract The Cretaceous was the starting point when the Laramide Orogeny began to fault and fold as a result of tectonic activity which pushed the Farallon plate into the North American plate forcing the subduction of the Farallon. This subduction caused the plate to melt and form magma that either formed laccoliths, or intruded country rock with different igneous compositions. These compositions ranged from alkaline to mafic to rhyolitic based on their interactions as they made their way to the surface with country rock.…

    The research studies reveal the changing dynamics and showed that earth is left as the only planet in the solar system with the movement of tectonic plates. The studies also show that the planets like Mars and Venus had the same types of plates but they have not been detected for a long time. According to the geologists the major tectonic plate in the earth’s crust are Eurasian, North American, South American, the African, the Antarctic, Pacific and Indoaustralian plates. However along with the plates mentioned above there are some micro and secondary plates in the earth…

    It is interpreted to extend southwards into the United States below the Williston basin and extends northeast into Nunavut and northern Quebec wrapping around the Archean Superior craton (Ansdell, 2005). The THO is the end result of the closure of the Manikewan Ocean (Stauffer, 1984) which resulted in the formation juvenile crust which was eventually accreted onto the Archean Superior and Hearne cratons as well as a number of smaller cratons including the Sask Craton (Lewry et al. ,1994). The THO preserves a relatively complete tectonostratigraphic evolutionary history including evidence for rifting (ca. 2450-1950 Ma), the formation of oceanic crust (ca. 2000-1800 Ma), and sedimentary assemblages deposited along continental margins and younger (1880-1830 Ma) collisional and foredeep basins (Ansdell, 2005). The southwest exposed portion of the THO in the Canadian Shield is known as the Manitoba – Saskatchewan Trans-Hudson Orogen (MS-THO).…

    Besides the granite of which there is a plethora of, diorite and monzonite also formed as a result of the cooling of molten rock under the earth’s surface. These rock formations were the result of the natural geological process of subduction in which the Pacific Ocean plate is forced underneath the advancing North American Continental plate. Critically hot water from the subduction of the ocean floor, rose upwards about 75-100 kilometers and melted rocks in its path, creating the volcanic activity that gave rise to rock formations away from the subduction zone. The time at which all these process are dated to have taken place is during the Cretaceous…

    Bird tested this theory by using Computer modeling. In his simulation bird based the earth on the 'Jelly Sandwich ' theory which states that the earth 's crust is floating on a layer of partially molten upper mantle which is then underlain by a dense layer of mantle called mantle lithosphere. In Bird 's computer models he was able to adjust variables such as the strength of the lithosphere and the amount of friction generated between the two plates. After testing Bird concluded that even in simulations with relatively low amounts of friction the strain created was still great enough to deform the upper portion of the lithosphere by 5-10%. Which he believed would have been more than enough to create the Rock Mountains and explain its strange features (Bird,…

    Most of earths movement is caused by the thermal convection currents in the mantle. This causes hot lava to rise and cool lava to sink. The flooding magma causes the plates to move along with them. The convection currents are caused by the intence heat of the core and the cool air in the lithosphere. During this change in temperature,…

    The topic of this discussion is to explain why Africa and South America are moving apart. The drifting apart of Africa and South America has to do with the theory known as the theory of plate tectonics. Based on this model, the crust the coolest part of the mantle, make up Earth’s strong outer layer, known as the lithosphere. Right beneath the lithosphere is the asthenosphere, the hottest part of the mantle. Rocks at this depth are very near the melting temperature, and respond to forces by flowing similarly to the way a thick liquid would.…

    According to Christopher Scholz and his two colleagues, “The sudden movement of the Earth caused by the abrupt release of accumulated strain along a fault in the interior,” meaning an earthquake is the sudden movement along a fault line, which is where tectonic plates meet. When the plates shift this causes the Earth to shake but when the plates become unrestrained large earthquakes occur. The earthquake is not something that happens in one moment, it is a gradual buildup of pressure in one area that when released can cause large…

    The theory was developed in the 1960’s and the 1970’s, and oceanographers were gathering new information on the movement of our Planet. Earth’s outermost layer is proposed to be in seven different plates. There is the African plate, North American and South American plate, Eurasian, Australian, Arctic and Pacific Plate. There also other smaller boundaries such as the Philippines and the Scotia plates. The plates move all over the place, and the speed of the plates varies.…

    From the biggest cities to the smallest of molecules, the earth and its dynamics have been widely studied over the span of human history. Bright individuals have made astounding discoveries that has allowed the human race to come closer to finding an answer explaining the forces at work around them. Starting from the early days of the Grecian empire with Aristotle and Plato to the challenging ideals of Newton and Copernicus, science has been completely redefined and continues to grow as a result. Thomas Kuhn described particular scientific events, such as the transition from Aristotelian to Newtonian physics, as a paradigm shift that is realized when questioning the flaws of the then understood subject. The paradigm shift can be viewed…
