Unformatted text preview: seismic velocity of the crust, mantle, and core. Draw a diagram showing the travel paths of body waves through the earth as they propagate away from an earthquake (see Fig. 10-2). Why are these paths curved? Identify the shadow zone and explain why it exists. Indicate where we receive only pwaves, and explain why s-waves are not observed everywhere that p-waves are observed. How do we know the distribution of temperature in the interior of the earth? Why is the interior hot? What effect does increased temperature have on the response of earth materials to stress? Terms to know anticline syncline crust plunging fold strike dip fault compression extension normal fault reverse fault lateral fault tectonics stress strain brittle elastic plastic seismometer p-wave s-wave body wave surface wave seismic refraction seismic reflection epicenter focus outer core inner core low velocity zone Mohorovicic discontinuity Moho mantle...
