Earthquake & Volcanoes Unit Review Vocabulary to know: active volcanoes basaltic materials compression force dormant volcanoes extinct volcanoes hot spots liquefaction Modified Mercalli Scale primary waves rhyolitic materials seismic waves seismograph slippage tension force volcano aftershocks body waves convergent plate boundary earthquakes fault line intensity magma Moho discontinuity reverse fault S-wave seismogram shear force strike-slip fault transform fault boundary alpide zone cinder cone crater elastic limit focus lava magnitude normal fault Richter Scale San Andreas Fault seismology shield cone surface waves tsunami andesitic materials composite cone divergent plate boundary epicenter granitic material L-wave mantle P-waves Ring of Fire secondary waves seismologist silica tectonic plates vent Concepts to know: Know how volcanoes are created. Know where volcanoes are distributed throughout the world. Know how hot spots are created. Know the different type cones and be able to explain the difference between them. Be able to explain how earthquakes, plate tectonics and volcanoes are related. Know the name of the three types of fault slips and be able to give an example of each. Be able to explain what happens when plates slip. Be able to locate an epicenter. Be able to explain how liquifaction and tsunamis work. Be able to explain the Richter and Modified Mercalli scales. What to study for the test? The two biggest things to study are the notes and the readings. Pay special attention to the chapter reviews. Also look over any labs and activities that we have done. I try to pull questions from them as well.
