Plate Tectonics & Topographic Map Test REVIEW

Refer to the diagram to the right to answer the following three questions.

1. Label each layer in the diagram of Earth.

2. Label the missing layer.

3. When volcanoes form, magma, or melted rock, rises from underground and produces a bulge. Over time, this bulge grows and increases in pressure until an eruption occurs and magma flows out. Just before an eruption occurs, the magma is found in which layer of the earth?

4. A huge segment of Earth’s crust that is slowly moving is called ____________

5. The Theory of Continental Drift states that millions of years agoA. Earth looked much the same as it does today.B. Earth had several large continents located mainly in the Northern Hemisphere.C. Earth was totally covered with water.D. Earth had one large landmass called Pangaea.

6. The theory of continental drift was developed by _______________________

7. What was the first piece of evidence supporting the idea of continental drift?

8. Similar fossils have been found in South America and Africa. This would indicate:A. that South America and Africa were once one landmass.B. that ancient animals were powerful swimmers.C. that animals crossed on a land bridge between present-day Alaska and Asia.D. That prehistoric birds were able to fly between the two

landmasses.

9. Two hundred fifty million years ago, the Atlantic Ocean did not exist. What is one of the forces that helped form this ocean?

A. The North American and South American plates began to collide.

B. The Australian and Indian plates separated.C. The Mid-Atlantic Ridge caused African and South American

plates to push apart.D. The African plate began breaking apart.

10. What do scientists believe is responsible for the movement of the plates that form the Earth’s crust?

11. Where would the youngest ocean floor be found? (A-D)

12. Which area above would show an area with a convergent plate boundary? (A-D)

13. Which area above would show an area with a divergent boundary? (A-D)

14. Where would a subduction zone be located? (A-D)

15. Where would the ocean floor be the oldest? (I-IV)

16. What is the name of the landform that can result at location A?

17. What is the name of the landform that can result at location B?

18. Which section of plate (I-IV) would be the most dense?

19. Crust material is forced downward and remelted at __________ zones.

20. Plates in transform boundaries A. remain stationary.B. are under tension and are being pulled apart.C. slide horizontally past each other.D. are under compression and are being pushed together.

21. The following characteristics describe features at either a mid-ocean ridge or ocean trench. Place an “R” next to the description if it describes a mid-ocean ridge or a “T” next to the description if it describes an ocean trench.

- The corresponding rock layers on either side of the formation are the same age. _- The ocean floor is wider now than in the past. ______- Located at a subduction zone. ______- There is evidence of recent volcanic activity. ______- Located at a divergent boundary. ______- One plate is more dense than the other plate. ______- Located at a convergent boundary. ______- Occurring between an oceanic and oceanic plate. ______- Occurring between an oceanic and continental plate. ______
