b. Richter
c. Rigidity
d. Moment Magnitude
4. A break in the Earth’s crust where slabs rub against each other during movement is a(n)____________.
a. epicenter
b. fracture
c. fold
d. fault
5. Which is not a type of fault?
a. normal
b. reverse

b) epicenter
c) ground zero
d) convergence point
7. Which type of earthquake waves are fast, push-pull waves?
a) S waves
b) P waves
c) surface waves
8. Which type of earthquake waves can go through solids, liquids, and gases?
a) S waves
b) P waves
c) surface waves d) seismic sea waves
9. What is a “tsunami”?
a) a seismic sea wave
b) a huge hurricane wave
c) a tidal wave
d) a giant wave caused by wind
10. A normal fault is created by which type of force?
a) shearing b) compressional
c) tensional
II. True/ False: Write out the words True or False below. If the statement is true, write true. If false,
write False and change the underlined word to make the statement true.
F-compression 11. The type of stress that pushes rock together causing a collision is tension.
F-epicenter
12. The focus is the point on the Earth’s surface where an earthquake begins.
True
13. Compression is a type of stress that causes the Earth’s landforms to change shape.
True
14. Seismologists can determine the magnitude of an earthquake based on information
collected at seismograph stations.
True
15. A majority of earthquakes occur at plate boundaries.
III. Short Answer:
16. List 3 seismic waves and list the characteristics for each wave.
Pwave-1st, push/pull, travel through solids, liquids, gases
Swave- 2nd, side to side, up and down, solids only
Surface- last, most destructive, rolling motion, travel only on surface.
