Unit Review - Tectonics
1. Label and identify all of the layers of the Earth’s interior. With your diagram,
place thicknesses, composition, and whether it is solid or liquid
2. Explain in your own words how the plates of the earth’s crust move around.
3. In the “boat in water” analogy, which layer is the “water”, and which layer is
the “boat”?
4. Name five large plates (and test yourself to see if you can give their approx..
geo location)
5. Do all plates move in the same direction? Do they all move in the same
manner?
6. What are the three types of plate movement? Draw a quick sketch to go
along with your definition
7. At convergent boundaries, the force of the two plates colliding usually
creates what kind of zone?
8. Draw a diagram of a convergent boundary. Label all necessities.
9. Explain what happens at a subduction zone. What are the usual
characteristics?
10. Throughout the world, where are some examples of subduction zones?
Provide at least 3.
11. What is a divergent boundary? Provide a diagram to go along with your
definition.
12. What is usually associated with a divergent boundary? (think “oceans”)
13. What are some examples of world locations where there is a divergent
boundary? Provide at least 2.
14. What is a transform boundary? Draw a diagram to go along with your
definition.
15. What is a famous transform boundary close to home? What cities or area
does it affect?
16. What is the ring of fire? Which countries are surrounding the ring of fire?
Why is it so active?
17. What are some similarities between the ring of fire and a lot of the worlds
mountain ranges? Explain by using proper terms.
18. What is Pangea? What is proof that this type of world could have existed?
Provide 4 reasons.
19. What is an earthquake? What causes an earthquake? Where do most
earthquakes occur worldwide?
20. Where have been some of the worst earthquake disasters in world history?
Provide some countries.
21. Explain the following terms by using a diagram: focus, epicenter, fault line
22. What are the two types of waves that are released when an earthquake
occurs? Which wave is faster? Which wave is more destructive?
23. An earthquake’s intensity is dependent on four things. What are they?
24. Explain with reference to focus and epicenter why some earthquakes are
more destructive than others?
25. What besides the shaking of the ground causes a lot of damage in
earthquakes? Provide 3 things
26. What makes the above 3 so bad? Explain.
27. Define: lava, magma, vent, eruption, pyroclastic debris, volcano, active,
dormant, extinct
28. How can volcanoes help understand what is inside the earth? Explain.
29. Draw and define a shield volcano. Are they explosive? Provide some world
examples
30. Draw and define a cinder cone volcano. Are they explosive? Provide some
world examples
31. Draw and define a composite volcano. Are they explosive? Provide some
world examples
32. Explain why the following make volcanoes some of the worst natural
disasters: lahars, pyroclastic flows, tephra
33. Where is the largest volcano in the universe? How big is it?
34. What are the most important facts YOU need to know for the country you
chose for your assignment? Think about: top 3 earthquakes, top 3 volcanoes,
largest tsunami or other disasters as a result of tectonic forces, type of
boundaries and results, etc.
