1 5 1 Which of the following disasters would you most likely experience in San Francisco? A) B) C) D) E) 2 earthquakes due to movement along faults meteorite impact nuclear explosion undersea landslides volcanic activity 5 2 Earthquakes that occur along faults are created when __________________. A) B) C) D) E) 3 melted rock is erupted along the fault zone water is squeezed out of rock and released along the fault stress builds up until rocks break the earth shifts and moves along fractures answers C and D 5 3 The type of energy that shakes the Earth during an earthquake is produced by __________________. A) B) C) D) E) gravitational attraction density variations shock waves heat solar energy 4 5 4 Which of the following might provide evidence that a fault zone exists in an area? Lines or lineaments on the surface of the Earth as seen from above A) the zone. B) C) D) E) 5 Streams that are offset or end abruptly. Tilted layers of rock that were originally horizontal. Offset rock layers. all of the above 5 5 A fault is a fracture plane that extends into the Earth. If the footwall of an inclined fault moves down relative to the hanging wall then the fault type is a ___________________. A) B) C) D) E) 6 strike-slip fault normal fault reverse fault abnormal fault transform fault 5 6 If the hanging wall of an inclined fault moves down relative to the footwall then the fault type is a ________________. A) B) C) D) strike-slip fault normal fault reverse fault abnormal fault E) 7 transform fault 5 7 On the Alpine fault in New Zealand, gold-bearing rocks and gravels were offset (refer to Figure 4.6). Gold-bearing rocks in the Nelson province were offset to the north from gold-rich gravels in the Otego province. Since most of the movement along the fault is horizontal it can be classified as a A) B) C) D) E) 8 Transform fault. Left-lateral strike-slip fault. Right-lateral strike-slip fault. Reverse fault. Dip-slip fault. 5 8 You are hiking east across a sequence of rock layers that are tilted 45° to the east. At some point you cross a small linear depression and notice that there is a repetition of the layers that you just walked over. This repetition of rock layers provides evidence that you have crossed a ________________. A) B) C) D) E) 9 strike-slip fault normal fault reverse fault abnormal fault transform fault 5 9 The most common types of faults in an area being pulled apart between two tectonic plates are ___________________. A) left-lateral strike-slip faults right-lateral strike slip faults B) C) D) E) 10 reverse faults normal faults horsetail faults 5 10 The most common types of faults in an area being pushed together between two tectonic plates are _____________________. A) B) C) D) E) left-lateral strike-slip faults right-lateral strike slip faults reverse faults normal fault horsetail faults
