Which

ABC

D

2. Which letter points to the YOUNGEST ocean crust?

3. A CONVERGING plate boundary is occurring at letter:

4. The convection currents of magma occur in the __________ layer of the mantle (Lithosphere, Asthenosphere, Mesosphere)

5. The plates are made up of these these two layers of Earth:

6. The patterns of magnetic striping on the sea – floor indicate that …

a. Rocks of the ocean floor are all the same age.b. Rocks of the ocean floor vary in agec. Rocks of the ocean floor are the oldest on the

planet.

7. Which choice/choices are results of this plate movement?A. Earthquakes B. VolcanoesC. New Ocean Crust D. Island formation

8. This plate movement is taking place in …

a. Japan b. Iceland c. East Africa d. California

9. This is a (Convergent/ Divergent/ Transforming) plate boundary, called _____________________.

10. It is currently occuring in __________.

11.Circle the results of this plate motion :

a. EQs c. Volcanoes e. Rift Valley

b. Trench d. M.O.R.s f. Narrow Sea

AB

C

12. Which of the locations above would you expect to find volcanic activity? A? B? C? (or a combination)?

13.Which location is the likely location of a trench?

14.Which location has the youngest crust?

15. Identify the plate movement that is taking place in the diagram above.

16. Describe what is happening.

17. When two plates collide, what determines which one will sink back into the mantle?

18.Which letter shows the location with the least tectonic activity?

19.Would you expect to find volcanic activity at C? Why or why not?

20. Explain HOW the Mediterranean has shrunk over time. What plate movement would be responsible?

Answers1. C 12. B & C

2. A 13. B

3. C 14. C

4. Asthenosphere 15. Subduction

5. Crust & upper mantle 16. An ocean plate collides with a land or ocean plate and sinks back into the mantle.

6. B 17. Density – the ocean plate sinks into the mantle because it is made of denser rock.

7. A 18. E

8. D 19. No vocanoes where 2 land plates collide (Mt. Building)

9. Divergent

10. E. Africa

11. A, C, E, & F

20. Subduction destroys oceanic crust and will shrink an ocean in size over time.

Be sure to study…• Vocabulary• Wegner’s Continental Drift & his evidence• Plate Tectonics• What layers make up plates?• Why do plates move?• Describe what is happening in a convection current & why it

happens• Identify sources of heat driving convection currents.• Discoveries in the sea – floor that confirmed sea floor spreading

& plate tectonics• What is the evidence to support Hess’s Sea-floor Spreading theory (2

pieces)?• Describe how the sea-floor is recycled in a conveyor belt fashion.• Compare types of plate movements – Description, Results, &

Location– Seafloor Spreading; Rifting; Subduction; Mt. Building; Transform
