SES4U Plate Tectonics Unit Test Review Questions: – Volcanoes: List three factors that determine the nature of a volcanic eruption. What role does each play? Why is a volcano that is fed by highly viscous magma likely to be a greater threat than a volcano supplied with very fluid magma? Describe pahoehoe and aa lava. Describe the three types of volcanoes. What is the Ring of Fire? What type of plate boundary is associated with the Ring of Fire? What is the source of magma for intraplate volcanism? Why are the oldest Hawaiian islands no longer volcanically active? Text p. 362 363 #9-12, 14-18, 21, 24, 25, 28, , 29 – Earthquakes: What are foci, and faults, epicenters? Explain what is meant by the term elastic rebound? Why are faults that experience considered more dangerous? no active What are the major differences between and waves? P S Which type of seismic wave causes the greatest destruction to buildings? An earthquake measuring 7 on the Richter releases about _______________ times more energy than an earthquake with a magnitude of 6 and has an amplitude that is ___________ times greater. In addition to the destruction created directly by seismic vibrations, list three other types of destruction associated with earthquakes. What is the difference between and the Mercalli scale Richter scale? What is a How is it generated? tsunami? Why might an earthquake with moderate magnitude cause more extensive damage than a quake with high magnitude? What evidence do we have that the Earth’s outer core is molten? What is the difference between the physical makeup of the and the athenosphere lithosphere? Text p. #10-20, 26, 30, 34-37 Plate Tectonic Theory: List the evidence that Wegener and his supporters gathered to substantiate the continental drift hypothesis. Explain why the discovery of the fossils remains of in both South America and Mesosaurus Africa, but nowhere else, supports the continental drift hypothesis. What are the three major types of plate boundaries? Describe the relative plate motions at each of the boundaries. What is seafloor spreading? Where is active seafloor spreading occurring today? What is a subduction zone? With what type of plate boundary is it associated?
