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
7. What do you call sections of a fault that have very little earthquake activity?
Plastic rebound Elastic rebound Seismic gap
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.
14. What causes the ground to move during an earthquake?
Plastic deformation Elastic rebound Stress Tectonic force
16. Body waves are the two fastest seismic waves they include.....
P waves (primary) S waves (secondary) 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 __________.
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
