GLG111.D Study Guide Spring 2009 Chapter 3: Plate Tectonics, p. 52-73 Define the following terms: Plate tectonics: groups of rocks all moving in the same direction Convection: transferring heat by physically moving around material (warmer materials rise, colder materials sink) Divergent plate boundaries: move away Convergent plate boundaries: move together Transform plate boundaries: horizontally slide past each other Subduction zone: one plate sinks into the asthenosphere Concepts to know : 1. List two lines of evidence used in support of Plate Tectonics (that plates are moving)? Fossils, glacial, fitting coastlines, mountains, ridges 2. Why are there plates? Our earth is still hot, the asthenosphere (elastic) supports rigid rocks on top and moves them around. 3. Why do plates move relative to one another? -plates are pushed and pulled (subduction zone) across the earth 4. How fast do plates move? -between one – twelve centimeters per year

Use the table posted on our BB site in the study guide folder titled chapter 3_part 2. 8. Make sure you can draw a cross-section with all important layers (continental/oceanic crust, lithosphere, asthenosphere, trench, volcanic/continental arc) labeled for the following types of plate boundaries: A) Ocean-continent convergent B) Ocean-ocean convergent C) Continent-continent convergent D) Oceanic divergent 2...
