Plate Tectonics Test Study Guide Mary George King Core 1 ScienceMrs.Bannister

#1 - #3 1.Name the three main layers of the Earth: Core, Mantle, and Crust 2.What part of Earth is densest? Core 3.Name the two parts of the core and describe the each: Inner Core: Hot solid metal Outer Core: Liquid metal

#4 - #6 4. What layer of the Earth is thickest? Mantle 5. What layer of the Earth in thinnest? Crust 6. Name and describe the 2 types of crust: Continental- Under the continents Oceanic- Under the oceans

#7 - #9 7. What layer of Earth contains all living things? Crust 8. Describe the parts of the lithosphere: Crust and upper mantle 9. The lithosphere rests on the: asthenosphere

#10 -# These fit together like pieces of a puzzle: Tectonic Plates 11. What scientists came up with the continental drift theory? Alfred Wegner 12. Explain the continental drift theory: All continents used to be large landmass and overtime they drifted apart

#13 - # Give three types of evidence. Wegner uses to prove his theory: Fossils, climate, and types of rock. 14. Name the supercontinent: Pangaea 15. T or F The tectonic plates of Earth move.

#16 - # T or F The sea floor is smooth and level. 17. Huge under water mountains ranges are called: mid-ocean ridger 18. The sinking and rising motion of the molten rock of the mantle is called a: Convection current

#19 - # Explain the theory of plate tectonics: The Earth’s surface is made up of plates that move. 20. T or F Plate movement causes changes in the Earth’s crust. 21. Name three ways that plates can move: 1) Pushing Together 2) Pulling Apart 3) Scraping Past Each Other

# Give 2 results of plate movement: Earthquakes, volcanoes, and mountains
