Plate Tectonics Test Study Guide 2016 TOPICS: Earthquakes Plate Movement and Boundaries Landforms at Plate Boundaries Continental Drift Hypothesis Seafloor Spreading Forces that cause Plate Movement Earthquakes You should be able to: Describe why most earthquakes occur near plate boundaries. Describe the formation of tsunamis (Japan’s Killer Quake). Describe what seismic waves are. KEY VOCAB: earthquake, seismic wave, tsunami Plate Movement and Boundaries You should be able to: Explain the three ways one tectonic plate can interact (collide, divide, slide) with another tectonic plate. Describe the three types of plate boundaries (convergent, divergent, transform). Describe the type of stress (compression, tension, shear) that occurs at each type of plate boundary. KEY VOCAB: tectonic plate, plate boundary, convergent, divergent, transform, compression, tension, shear, collide, divide, slide, density, oceanic crust, continental crust Landforms at Plate Boundaries You should be able to: Explain each type of landform that could possibly occur at each plate boundary. Describe, in general, how/why each landform is created. KEY VOCAB: mountain, volcano, volcanic arc, volcanic island arc, ocean trench, subduction zone, mid-ocean ridge, continental rift valley, new oceanic crust, old oceanic crust, continental crust, fault zone, density Plate Tectonics Test Study Guide 2016 Continental Drift Hypothesis You should be able to: Define Pangaea. Describe the pieces of evidence that Alfred Wegener used to create the Continental Drift hypothesis. There are six (6) of them. Explain the CLIMATE, FOSSIL, and ROCK evidence that supports Alfred’s Continental Drift hypothesis. KEY VOCAB: Pangaea, Continental Drift hypothesis, Mesosaurus, Glossopteris, Glacier grooves, Appalachian Mountains Seafloor Spreading You should be able to: Describe how the theory of seafloor spreading proved Alfred’s Continental Drift hypothesis. Describe the four (4) pieces of evidence (mid-ocean ridges, temperature of oceanic crust, age of oceanic crust, magnetic signatures) that explain seafloor spreading. KEY VOCAB: seafloor spreading, magnetic signatures, magnetic field reversal, midocean ridge, temperature of oceanic crust, age of oceanic crust Forces that cause Plate Movement You should be able to: Explain the main driving force that causes tectonic plates to move. Describe how convection currents occur in the mantle (asthenosphere) due to unequal heating in Earth’s interior. Describe the three (3) secondary forces that cause tectonic plates to move (ridge push, slab pull, basal drag). KEY VOCAB: unequal heating, mantle, asthenosphere, tectonic plates, convection currents, magma, ridge push, slab pull, subduction zones, basal drag, conveyor belt, midocean ridge, density Plate Tectonics Test Study Guide 2016 Plate Tectonics Test Study Guide 2016 Plate Tectonics Test Study Guide 2016
