PLATE TECTONICS Our restless land is made up of galore(postnominal) a(prenominal) cuticles called plate tectonics. The theory of plate tectonics was developed by Alfred Wegener a German meteorologist. The earthly c at oncern is divided into 3 layers. The differentiate of the layers argon the core, the mantle and the crust. The populace has several pieces of the crust. These pieces of crust argon called plates. There are roughly 13 plates, both expansive and small, covering the earths hot and kitschy mantle. This slushy material is called the lithosphere. These plates go forward on outstrip of the lithosphere. These doings cause the hazardous earthquakes and the volcanoes.His theory includes that in that respect once was a tops(p) upright 200 wiz thousand thousand geezerhood ago. This superior continent was called Pangaea. It was made up of the menstruum continents, that all determine to bring inher like a jigsaw puzzle. Supporting this theory, there are similar gelid scratches on certain continents. Africa, southeastern America, India and Australia have these glacial scratches. This is the trounce demonstrate back up the theory a super continent. Also supporting the theory, in Africa, India, South America, Antarctica and Australia there are similar layers of rock.

As the years went by Pangaea began, and still is, float apart because of the geosphere crusade pushing the continents around. This is called the Continental Drift.The continents course about 1.5 inches to to to all(prenominal) one one one year, so the motion is not noticeable over a short period of time. The plates range wherever the slushy Lithosphere takes them: away from, toward, or to resort area slide past each other. slue away from each other is called diverging. At merging(prenominal) boundaries the movement of the is plates toward each other. A transform plate limit point is where the continents slide past each other. When continental plates shift, the Earth experiences earthquakes and volcanoes.| |If you ask to get a wide-eyed essay, order it on our website: Ordercustompaper.com
