2 1. The formation of mountains is due mainly to while the destruction of mountains is due mostly to. A. deposition of an alluvial fan; weathering by acid precipitation B. erosion by wind abrasion; deposition of a delta C. flash floods depositing sediment; waves washing sediment away D. the action of plate tectonics; the action of weathering and erosion 2. Which of the following land features would have been formed by deposition of sediment by wind? F. a cave G. a sea cliff H. a sand dune J. an alluvial fan 3. On a topographic map, a narrow, steep valley will appear as- A. An area of closed circle within circle contour lines. B. An area of V-shaped contour lines. C. An area with few or no contour lines. D. An area with contour lines arranged in a fan shape. 4. A student stands at the point marked X on the topographic map below. What height in meters must the student climb in order to reach the top of the hill? Record your answer on your answer document.

3 5. What is the elevation of X on the topographic map shown above? A. 10 meters B. 50 meters C. 100 meters D. 150 meters 6. Rocks in a rock tumbler recreate which process by which rock is broken down from contact with other rock or sediment, causing physical weathering? F. abrasion G. acid rain H. chemical weathering J. mass movement 7. As a river enters a larger body of water, sediments are deposited over a wide area. Which of these landforms is likely to be formed at the site of deposition? A. Cave B. Mountain C. Delta D. Valley 8. The processes that shape and reshape the landforms on the Earth's surface may take hundreds, thousands and even millions of years. The process in which caves and caverns are formed is due to the- F. physical weathering of rocks due to the water cycle. G. physical weathering of rocks due to plate tectonics. H. chemical weathering of rocks due to the water cycle. J. chemical weathering of rocks due to plate tectonics.

4 9. The diagram below is a portion of a topographic map. In which direction is the river flowing? A. To the left B. To the right C. To the top D. To the bottom 10. If the river in the topographic map illustrated in the previous question cut a deeper canyon over time, what would the topographic map of the area look like? F. G. H. J.

5 11. The satellite photograph below shows a large meteorite crater that is 1200 m in diameter and 170 m deep. This crater is located in a flat, arid part of north eastern Arizona. How will this crater most likely change over time? A. It will get deeper as it fills with water. B. It will rise up like a volcanic crater. C. It will become less deep as the rim erodes. D. It will widen as it fills with lava. 12. The relief of a topographic map is - F. how raised the print is on the map. G. the area that the map covers. H. the amount of time it takes to make the map. J. the difference between the highest and lowest elevations on the map. 13. The Earth's surface is constantly changing. This is mainly due to the - A. increased amount of decaying soil. B. average yearly rainfall. C. number of meteors in the night sky. D. action of wind, water, ice and waves.

6 14. 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 if you were to hike from point X to point Y? F. 120 m G. 140 m H. 160 m J. 180 m 15. Calculate the contour interval on the map shown above. Record your answer on your answer document.

7 16. The satellite photo below shows San Francisco, California, which has many miles of coastline and an inland bay. Which area of the coastline has most likely experienced the greatest effect of erosion from waves over hundreds of years? F. Area N G. Area P H. Area S J. Area T 17. In spring 2003 a natural rock outcropping in New Hampshire called the Old Man of the Mountain collapsed. Which of the following most likely loosened the rock and caused it to fall? A. Heat turning sedimentary rock into metamorphic rock B. Water freezing and thawing inside cracks in the rock C. Volcanic activity producing pressure at the rock s base D. Oxygen reacting with iron on the surface of the rock

8 18. Some students use this map to plan a hike from a road to a creek in an unfamiliar area. Which of these additional pieces of information would most help the students plan their hike? F. The scale used on the map G. The type of bedrock in the area H. The length of the creek on the map J. The location of the nearest large city 19. Identify the topographic feature above. A. A valley B. A hill C. A depression D. A landmass 20. What does a small closed contour line at the center of a "target-like" pattern of closed contour lines, such as the one in the diagram above, represent on a topographic map? F. The summit or peak of a hill/mountain. G. A flat plain. H. A depression or low area between two summits. J. A canyon.
