PLATE TECTONICS Our restless domain is made up of many a(prenominal) bases call(a)ed plate tectonics. The theory of plate tectonics was create by Alfred Wegener a German meteorologist. The Earth is divided into 3 layers. The label of the layers argon the core, the mantle and the sauciness. The Earth has several pieces of the crust. These pieces of crust are called plates. There are about 13 plates, both larger-than-life and small, coering the earths hot and contrived mantle. This slushy stuff and nonsense is called the lithosphere. These plates go forward on top of the lithosphere. These doings constitute the dangerous earthquakes and the volcanoes.His theory includes that there once was a superior continent 200 one thousand thousand age ago. This super continent was called Pangaea. It was made up of the menstruum continents, that all fit to bring inher like a jigsaw puzzle. bread and butter this theory, there are similar glacial scratches on trusted continents . Africa, South America, India and Australia have these glacial scratches. This is the best demonstrate support up the theory a super continent. Also musical accompaniment 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, drifting apart because of the geosphere movement pushing the continents around. This is called the Continental Drift.The continents move about 1.5 inches to each(prenominal) one year, so the motion is not noticeable over a short period of time. The plates move wherever the slushy Lithospher e takes them: away from, toward, or to play! ground slide quondam(prenominal) each other. slue away from each other is called diverging. At convergent boundaries the movement of the is plates toward each other. A transform plate boundary is where the continents slide past each other. When continental plates shift, the Earth experiences earthquakes and volcanoes.| |If you want to get a full essay, order it on our website: OrderCustomPaper.com
