6. Which part of the earthquake can be located far
below the earth’s surface? Epicenter Focus
Focus
7. What do you call sections of a fault that have very
little earthquake activity? Plastic rebound Elastic rebound Seismic gap
Seismic Gap
8. What type of gas and water lines are being used in areas where
earthquakes are likely to occur?
Flexible pipes, like a bendy straw.
9. The bending of rock is also called
Deformation Moho Shadow zone
Deformation
10. Where do the strongest earthquakes usually occur?
At divergent boundaries At transform boundaries At convergent boundaries
At convergent plate 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
Under a table or any furniture in the middle of the room.
12. Where are most strike-slip faults located?
At divergent boundaries At transform boundaries At convergent boundaries
Along transform 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
Elastic Rebound
15. What do Seismologists study?
Volcanoes Earthquakes ( Seismic waves)
Earthquakes
16. Body waves are the two fastest seismic waves they include.....
P waves (primary) S waves (secondary) Surface waves
S & P waves
17. These waves travel slower and cause the most damage.
P waves S waves Surface 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
The 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
Epicenter
20. When rock is _________, energy builds up in it. Seismic waves occur as this energy is
__________.
Elastically deformed, released.
21. If you are outside when an earthquake begins to occur what
should you do?
Lie face down away from buildings.
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
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
Along the edges of the earth’s tectonic plates.
24. A scientist that studies earthquakes is called a
Volcanologist Seismologist Biologist
Seismologist
25. Giant masses of the earth’s crust that make up the outermost
part of the crust are called:
Tectonic plates
