Structure of the Earth. The Earth is made up of 3 main layers:. Core. Mantle. Crust. Inner core. Outer core. Mantle. Crust. The Crust. This is where we live!. The Earth’s crust is made of:. Continental Crust. Evolution of the Earth. Cracks in the Earth’s Crust. The . crust. , when it is solid, acts as a . heat insulator. for the hot interior of the Earth.. The molten material in the mantle, . magma. , below the crust builds up tremendous heat and pressure. . Standard . S6E5.d . Recognize that lithospheric plates constantly move and cause major geological events on the earth’s surface.. What You Will Learn. Describe the three types of tectonic plate boundaries. . It is difficult for scientists to estimate the exact amount. How do they Move?. Plates move by floating on top of the Upper mantle (Asthenosphere). The plates move in a certain direction based on the flow of magma beneath them. 4 Layers of the earth. 7 main plates of the earth. 3 main plate boundaries. 2 types of crust. 3 main features of plate tectonics (F.E.E.D). 3 main theorists and theories. Human interaction. Structure of the Earth. Tectonic Theory . Jessica Wilsey. A UDL lesson plan. What is plate . tectonic theory?. Plate tectonics . is a . theory. that describes the movements of the Earth’s . lithosphere. . . The lithosphere is made of 8 major plates and many minor plates. . (Noun). The . pieces of the Earth’s crust that float on the mantle. , causing continental drift and earthquakes and creating volcanoes, trenches, and mountains.. “The Earth’s crust is divided into . Plates. by. Katie . Lanoue. and Jeanine Brown. The Formation of a Theory. In 1915, a German scientist named Alfred Wegner came up with the theory of continental drift.. His hypothesis was that all the continents were once connected to form a supercontinent called Pangaea.. CONTINENTAL DRIFT THEORY. ALFRED WEGENER . proposed all continents . . originally formed from one landmass . . (PANGEA). EVIDENCE OF CONTINENTAL DRIFT:. . 1. Fossilized tropical plants in Greenland. Divergent. Convergent. Transform. Three types of plate boundary. Spreading ridges. As plates move apart new material is erupted to fill the gap. Divergent Boundaries. Iceland has a divergent plate boundary running through its middle. plates meet. In what ways do the plates move? . 3 types of plate movements we need to know: . Convergent: . Plates move together. Can be split into destructive (oceanic and continental crust) and collision (continental and continental) . Rocks, soils, minerals, sediments, magma. The Grand Canyon, AZ. https://www.youtube.com/watch?v=WwiiOjyfvAU. What are the layers of the Earth?. Layers of the Earth. Crust. - O, Si, Al . Mantle. - O, Si, Mg, Fe. Plate tectonic cycle . Plate tectonics -. What is plate tectonics?. Concept that features of the earth and earth phenomena (earthquakes, volcanoes) are caused by motion of plates of rigid lithosphere moving on a plastic asthenosphere. Ghafoor. 5. th. hour. 12-9-16. Oceanic V.S Continental Crust . Oceanic Crust . It is composed of several layers, not including the overlying sediment. . Oceanic crust is about 6 km (4 miles) thick..
