ESS 20152016 Influence on Evolution amp Biodiversity Assessment Statement Explain how plate activity has influenced evolution and biodiversity Speciation through physical barriers Consequences of isolation for evolution. Simplified Plate Tectonics MapPlate boundary - Known area between two plates.Some plate boundaries, such as the North America - South America boundary, are not shown because scientic dataare inadequa Robert T. Pappalardo. Jet Propulsion Laboratory,. California Institute of Technology. Copyright 2012 California Institute of Technology. Government sponsorship acknowledged.. Ganymede’s Tectonics: Outline. 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.. One moves oil, while the other builds mountains. Which can do more work?. Supertanker . Tectonic Plate . Mass - 2 x 10. 8. kg. Velocity - 8 m/s. Mass - 3 x 10. 20. kg. Velocity - 1 x 10. -9. m/s. Volcanism is mostly focused at plate margins. Pacific Ring of Fire. This map shows the margins of the Pacific tectonic plate and surrounding region. The red dots show the location of active volcanism. Notice how the majority of the volcanism is focused in lines along the plate boundaries? For this region is the area known as the “Pacific Ring of Fire”.. Composition of the Earth: . Layers of the Earth: . Crust: . 5-100km thick. . Oceanic crust: thin and more dense, mostly basalt . Continental crust: thicker and less dense, made up of more granite than oceanic crust . 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. Volcanism is mostly focused at plate margins. Pacific Ring of Fire. This map shows the margins of the Pacific tectonic plate and surrounding region. The red dots show the location of active volcanism. Notice how the majority of the volcanism is focused in lines along the plate boundaries? For this region is the area known as the “Pacific Ring of Fire”.. 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. . Beloussov. (1907-1990). Famous opponent of plate tectonics. Structural Geologist and Geodynamicist. Director of Geodynamics . Dept. , . Inst. of the Physics of the Earth. Member of Soviet Academy of Sciences (appointed 1953). 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. What is Geology. Geo. - Earth. Ology. is the study of. This activity will help us study the earth by learning what it is made of and how it can be changed. 4 layers of the Earth. Crust. Mantle. Inner core. http://sos.noaa.gov/datasets/Land/paleo.html. Animations. . On the move…. Plate Tectonics: . the rocky history of an idea. Ever notice that the shore lines of South America and Africa seem to fit together?.
