PLATE TECTONICS Our restless res publica is made up of many a(prenominal) dwellings c solelyed 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 gall. The Earth has several pieces of the crust. These pieces of crust are called plates. There are about 13 plates, two larger-than-life and small, c all overing the earths hot and mushy mantle. This slushy sensible is called the lithosphere. These plates go forward on top of the lithosphere. These doings endeavor the dangerous earthquakes and the volcanoes.His theory includes that there once was a top-notch 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. maskingup this theory, there are similar glacial scratches on certain(p) continents. Africa, South America, India and Australia have these glacial scratches. This is the best demonstrate back up the theory a super continent. Also reinforcement 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 lithosphere movement pushing the continents around. This is called the Continental Drift.The continents move about 1.5 inches to for each one one year, so the motion is not noticeable over a short period of time. The plates move wherever the slushy Lithosphere takes them: away from, toward, or to playground slide onetime(pr! enominal) 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
