21. A topographic map is shown below. The topographic map above shows the elevation of nature trails in a state park. The first trail extends from the point labeled X to the summit, labeled Y. The second trail extends from the point labeled Z to the summit, labeled Y? What is the change in elevation for the steepest trail from the beginning of the trail to the summit?

140

In an area known as The Ring of Fire, volcanic island chains have formed in the Pacific Ocean. What most likely caused this to happen? A. Convergent plate boundary B. Divergent plate boundary C. Transform plate boundary D. Mantle hot spot

A. Convergent plate boundary

13. The diagram below is a portion of a topographic map. According to the diagram above, which direction would you expect a delta to be formed? A. To the left B. To the right C. To the top D. To the bottom

A. To the left

19. Where would the ocean floor be the oldest? A. 1 B. 2 C. 3 D. 4

B. 2

3. Which of these landforms would most likely be found at a divergent boundary? A. Fault line B. Mid-ocean ridge C. Volcanic island D. Mountain

B. Mid-ocean ridge

7.According to the diagram above, what is occurring as a result of the plate collision? A. A mid-ocean ridge is forming. B. Subduction is occurring because oceanic crust is denser than continental crust. C. A divergent boundary is forming. D. A transform boundary is forming due to two plates sliding past one another.

B. Subduction is occurring because oceanic crust is denser than continental crust.

15. Use the topographic map above to predict how the land form may be reshaped by weathering. A. Weathering could reshape the top of the land form to increase elevation. B. Weathering could reshape the top of the land form to decrease elevation. C. Weathering could reshape the right side of the land form to create a cave. D. Weathering could reshape the land form to create a canyon.

B. Weathering could reshape the top of the land form to decrease elevation.

17. The diagram below models two continental plates. Which type of continental plate movement formed the mountains modeled in the above diagram? A. Divergent B. Transform C. Convergent D. Subduction

C. Convergent

5. The diagram below models two tectonic plates sliding past one another. This type of plate movement is common with oceanic plates. As the plates push against one another, pressure builds up in the form of tension. All of the tension is released when the plates begin to move. According to the information and diagram above, which force is responsible for the plate movement? A. Balanced B. Gravitational C. Frictional D. Unbalanced

C. Frictional

1. According to the diagram above, where would the youngest ocean floor be found? A. I B. II C. III D. IV

C. III

9.The satellite image below shows the Appalachian Mountains located in Pennsylvania. The Appalachian Mountains formed when the North American and African plates formed a convergent boundary. The two plates have since formed a divergent boundary over millions of years as the continents have drifted away from each other. Weathering, erosion, and the change in type of plate boundary have significantly changed the shape of the Appalachian Mountains over time. Refer to the information and image shown above. Which statement below describes how these mountains will most likely change over time? A. The mountains will increase their elevation over time. B. The mountains will become more steep and jagged over time. C. The mountains will become rounder and less steep over time. D. The mountains will spread into the state of Louisiana.

C. The mountains will become rounder and less steep over time.

2. Which area on the terrain above would show an area with a convergent plate boundary? F. A G. B H. C J. D

F. A

12. Scientists believe that convection currents within the____ are responsible for the movement of the plates that form the Earth's crust. F. Asthenosphere G. Lithosphere H. Inner core J. Outer core

F. Asthenosphere

10. Which of the following geographical features could form when two plates collide? F. Trench G. Mid-ocean ridge H. Transform fault J. Delta

F. Trench

4. Which scientist is credited for first proposing Continental Drift Theory? F. Albert Einstein G. Alfred Wegner H. Abraham Ortelius J. Harry Hess

G. Alfred Wegner

16. Alfred Wegener noted that fossils from a particular type of reptile were found on both sides of the Atlantic Ocean. Which of the following would be the best explanation of how this occurred? F. They swam across the ocean. G. The Atlantic Ocean did not exist in earlier times. H. They walked across a giant land bridge that has weathered away. J. They walked across an ice bridge located near the equator.

G. The Atlantic Ocean did not exist in earlier times.

18. Which area on the terrain above would show an area with a divergent plate boundary? F. A G. B H. C J. D

H. C

8.Which of these landforms is most likely to be found at a convergent boundary? F. Fault line G. Mid-ocean ridge H. Mountain J. Rift valley

H. Mountain

20. The following is a model of how a volcano is formed in the ocean. Clay is used to represent lava coming out of the ground. The clay is pushed through a hole in the bottom of an aquarium. The following forms. You can see how the clay comes through the bottom, and slowly forms an island that is above the water. Afterwards, fishing line is used to cut off pieces of the island to show how the volcano will weather. Which of the following series of topographic maps represents the formation and weathering of the volcano in the clay model? F. 1, 2, 3, 4, 5 G. 2, 3, 1, 4, 5 H. 1, 3, 4, 2, 5 J. 1, 4, 2, 3, 5

J. 1, 4, 2, 3, 5

6. Which two continents did Alfred Wegener think looked like they fit together like puzzle pieces? F. North America and South America G. Europe and Africa H. North America and Europe J. South America and Africa

J. South America and Africa

14. The most recently formed crust of the Earth would be found — F. where plates moving sideways passed each other G. where one plate is going under another plate H. where two plates are pushing directly toward each other J. where two plates are moving away from each other in opposite directions

J. where two plates are moving away from each other in opposite directions
