1. What is the name of the instrument that records earthquake waves? • Seismograph • Seismogram
2. What type of plate motion is it when 2 plates move away from each other, causing weak, shallow earthquakes? • Divergent • Convergent • Transform
3. What type of plate motion is it when 2 plates move toward or into each other, causing strong, deep earthquakes? • Divergent • Convergent • Transform
4. What type of plate motion is it when 2 plates slide past each other, causing shallow, moderate earthquakes? • Divergent • Convergent • Transform
5. The picture of the seismic waves recorded are called? • Seismograph • Seismogram
6. Which part of the earthquake can be located far below the earth’s surface? • Epicenter • Focus
7. What do you call sections of a fault that have very little earthquake activity? • Plastic rebound • Elastic rebound • Seismic gap
8. What type of gas and water lines are being used in areas where earthquakes are likely to occur?
9. The bending of rock is also called • Deformation • Moho • Shadow zone
10. Where do the strongest earthquakes usually occur? • At divergent boundaries • At transform boundaries • At convergent boundaries
11. Where should you go if you are in a building when an earthquake occurs? • Outside • Into the hallway • Under a piece of furniture
12. Where are most strike-slip faults located? • At divergent boundaries • At transform boundaries • At convergent boundaries
13. What are the characteristics of “P” or Primary waves? • They can travel through solids, liquids, and gases. • They can’t travel through liquid • They travel the fastest and arrive first • They travel fast but arrive second after “S” waves.
P waves are the fastest, they arrive first, they can travel through solids, liquids, and gas.
14. What causes the ground to move during an earthquake? • Plastic deformation • Elastic rebound • Stress • Tectonic force
15. What do Seismologists study? • Volcanoes • Earthquakes ( Seismic waves)
16. Body waves are the two fastest seismic waves they include..... • P waves (primary) • S waves (secondary) • Surface waves
17. These waves travel slower and cause the most damage. • P waves • S waves • Surface waves
18. The actual point down in the earth where the rocks shift and start an earthquake is called….. • Epicenter • Moho • Shadow zone • Focus
19. This is located directly above the focus, it is the point on the surface of the earth where the earthquake occurred. • Epicenter • Moho • Shadow zone • Focus
20. When rock is _________, energy builds up in it. Seismic waves occur as this energy is __________.
21. If you are outside when an earthquake begins to occur what should you do?
22. If the S waves arrive a long time after the P waves this tells you that the earthquake is probably: • Close to the seismograph • Far away from the seismograph
23. Where do most earthquakes usually occur? • Along the edges of the earth’s continents • Along the edges of the earth’s oceans • Along the edges of the earth’s tectonic plates
24. A scientist that studies earthquakes is called a • Volcanologist • Seismologist • Biologist
25. Giant masses of the earth’s crust that make up the outermost part of the crust are called:
