4. Explain how tectonic plates move.
5. Describe the 3 types of seismic waves. Include: movement, damage done
pssurface6. Locate an epicenter from seismograph data. (virtual earthquake)
7. Determine Richter magnitude based on seismograph data (virtual earthquake)
8. Describe what you should do if an earthquake strikes.
9. Describe the factors that can affect the severity of an earthquake.
10. Describe the differences and usefulness of the Richter and Mercalli Scales. (if one is high and the other
low what info can that tell you?)
11. Recognize the 3 types of faults from pictures. (page 267)
12. Determine the age of islands formed from a hot spot and the direction of plate movement
13. Compare runny vs. thick lava. Which has more quartz? Type of volcano?

Composite
Cinder
Eruption type
Shield

crust-
mantle-
outer core
inner core
16. Explain how a tsunami can form.
17. Explain how an intraplate earthquake or volcano can happen. Site some examples of each.
18. What causes liquefaction?
