The Mechanism Of Plate Motion

The Mechanism of Plate MotionIt is resolve by now that thither is bm deep in the earth as attest by earthquakes and volcanoes . The question that comes to mind then is What is moving in the earth s interior ? Why and how is it moving These questions prompted a serial publication of scientific geologic studies , and in the 1960 s a photographic carapace architectonic theory (plate execution ) was formulated (Weil 2006 . In 1965 , Tuzo Wilson introduced the term plate for the broken pieces of the Earth s geosphere .in 1967 , Jason Morgan proposed that br the Earth s originate consists of 12 rigid plates that move relative to each other .in 1967 , Xavier Le Pichon published a synthesis showing the posture and type of plate boundaries and their direction of movement (Hawaiian Natural chronicle Association , The Birth of Plate Tectonics 2005In to understand plate motion , it is graduation exercise necessary to know the physical war paint of the earth s interior , for these elements are all involved in plate motion . Basic knowledge in cognition revealed that the interior of the earth is made up of layers of mantle and bitterness . The ones that are in the surface of the earth are the ocean crust and the continental crust . The oceanic crust is what we make the ocean floor and the continental crust is what made up the continental masses or lands that we know so closely (refer to figure1 ( conjecture 1 . From them we have the oceanic plates and the continental plates . These cardinal crusts along with the rigid upper mantle is what we call the lithosphere . Beneath the lithosphere is the athenosphere , which is made of plastic rocks under corking pres original ( Theory 1 . In other lyric poem , athenosphere empyrean is a very hot placeAlthough it is now clear with the geologists regarding the existence and movement of the plates , they are not still sure which exactly causes plate motion (Weil 2006 . They are puzzled mingled with two possibilities1 .

Mantle convection currents causes plate motion (Weil 20062 . Surface marge and plate forces causes plate motion (Weil 2006Between these two possibilities the geologists are primarily interested in proving or disproving the arguments that plates move only as a response to the athenosphere mantle convection currents , or that the plates themselves are the ones who causes the movement ( due to contact forces ) and consequently affecting the athenosphere mantle under (Weil 2006Let us now consider the mechanism of plate motion in detail by discussing the two possibilities . In the first possibility , convection (release of heat by boiling ) currents in the athenosphere are thought to be the cause of plate motion ( Theory 2 . Most geologists consider this phenomenon as the most potential cause of plate motions . As stated earlier , the area in the athenosphere is very hot and the molten rocks inside bring about less dense so that it rises up towards the edge of the athenosphere . As it rises , it left a void behind it so that the surrounding molten rocks move to...If you want to get a secure essay, order it on our website: Ordercustompaper.com
