PPT-Continental Drifts and Plate Tectonics

Who proposed the theory called Continental Drift Alfred Wegener What is Continental Drift A hypothesis that continents had drift or move apart What is Pangaea the supercontinent. Notes. Geology – . the study of the Earth and its processes. 2. The Earth’s. . Layers. Scientists study seismic (earthquake) waves and volcanic explosions to learn about the Earth’s interior.. Imagine the Earth as a hardboiled egg…………………….. The thin brittle shell is the crust that humans live on.. The thick jelly like white is the deep hot magma beneath the surface.. The yellow yolk is the core of the earth.. Earth habitable. ? . Earth is the only planet in the Solar System with plate tectonics. The outer crust of the Earth is broken up into regions known as tectonic plates. These are floating on top of the magma interior of the Earth and can move against one another. When two plates collide, one plate can go underneath another.. Chapter 12.2 BC Science 10. A Cross-Section of Earth. The Layers of Earth. Earth is over 1200 km thick and has four distinct layers:. Crust. – outer solid rock layer (granite on land, basalt in oceans). 6. th. year Geography. Learning Outcome. Revise Core Book. Chapters 1 – 3. Plate Tectonics. Earthquakes. Volcanoes. Examine the exam questions on these topics. Theory of Plate Tectonics. Earths plates move. Evidence for Plate Tectonics. Changes in Sea Floor Magnetism. Evidence for Plate Tectonics. Continents fit together like a puzzle. Changes in Sea Floor Magnetism. Evidence for Plate Tectonics. Fossils of plants and animals of the same species found on different continents. . Plate Tectonics. Became a theory in the 1960’s. Describes plate movements AND explains why they move. Plate Tectonics. Two types of crust: Oceanic and Continental. Plates are usually made of both. Continental Drift. Wegener's Theory. : . From 1912, Wegener introduced the theory of “ continental drift ,” arguing that all continents were once joined together in a single landmass and have drifted apart.. Theory of Plate Tectonics-. Theory that states the earth’s crust is broken into plates that float on lower mantle. Theory combines the theories of . continental drift . and . sea floor spreading . It states how and why . Plate Tectonics With Fruit Rollups and Graham Crackers Objective and Essential Questions Objective: Use models to describe how tectonic plates cause major geological events such as; ocean basins, earthquakes, volcanoes, and mountain building.
