17.4 - Cause of Plate Motions • • Mantle Earth’s interior between the _______________ and the _________________ Large-scale motion is believed to be the _________________ that drives the ___________________ of tectonic plates • Convection Transfer of ___________________ energy by the ___________________ of heated _____________________ from one place to another – Ex. Boiling water Heat comes from ____________________ within the mantle • Convection current Cycle of ____________ water rising and _________________ water sinking • • • • • • • Convection Currents _______________ of warm water ______________ and cool water ______________ – The cooling of matter causes it to _____________ slightly and increase in ____________________ – then it sinks due to __________________ – Warmed matter is then _________________ and forced to _____________ Convection Currents Develop in the ___________________ Moves the _______________ and outermost part of the ______________ Transfers thermal energy from Earth’s _______________ to its _______________ Rising material _________________ out, lifts and splits _________________ at _____________________ boundaries ____________________ movement pulls ___________________ boundaries • • Ridge push ________________ process associated with __________________ currents Occurs when the ___________________ of an elevated ____________ pushes an ____________________ plate toward a __________________ zone • • Slab pull ________________ process associated with convection currents in Earth’s _________________ Occurs as the ________________ of the ___________________ plate pulls the trailing ___________________ into a ____________________ zone. Written Response Sammy is warming a pan of soup on the stove. He gets the soup too hot and it begins to boil. a. Compare how convection currents in a warming pan of soup are similar to the convection currents inside Earth’s interior. b. Explain how this is the force behind plate tectonics. Use the following words in your open response: friction pressure heat radiation dense sinks evaporation lithosphere cools expand rise RUBRIC 4) * You correctly compare how convection currents in soup are similar to Earth’s interior. * You correctly explain how convection currents is the force behind plate tectonics and communicates ideas clearly * You demonstrate thorough understanding and/or choose more sophisticated processes. 3) * You correctly compare how convection currents in soup are similar to Earth’s interior. * You correctly describe how convection currents is the force behind plate tectonics. * You may demonstrate understanding of major concepts but may overlook or misunderstand some less important ideas or details. 2) * You correctly compare how convection currents in soup are similar to Earth’s interior. * You correctly describe only some important points how convection currents is the force behind plate tectonics. * You demonstrate that there are gaps in your conceptual understanding. OR *Your comparisons of how convection currents in soup are similar to Earth’s interior is minimal. * You correctly describe how convection currents is the force behind plate tectonics. * You may demonstrate understanding of major concepts but may overlook or misunderstand some less important ideas or details. 1) * Your comparisons of how convection currents in soup are similar to Earth’s interior is minimal. * You correctly describe only some important points how convection currents is the force behind plate tectonics. * You address only a small portion of the question. OR * You correctly compare how convection currents in soup are similar to Earth’s interior. * There are major errors as to how convection currents is the force behind plate tectonics. 0) *Your answer is totally incorrect or irrelevant. Blank) You did not give any answer at all.
