2 TEKS Check Plate Tectonics, Earthquakes and Volcanoes 1. All continental plates are moving, but not all mountain ranges are increasing in elevation. What accounts for this? A. Only mountain ranges with volcanic peaks are getting taller B. Not all plate movement produces compressional forces. C. Some plates are being subducted at a faster rate than mountain building can occur. D. Plate tectonics acts to maintain equilibrium. Erosion happens at the same rate as mountain building. 2. A hot spot is a place where volcanism occurs over a long period of time. It is thought to be the result of a "plume" rising from the Earth's mantle. Suppose there is a plume in the middle of an ocean plate. Over a long period of time the plate moves hundreds of miles. Which geological feature is MOST LIKELY to be produced by the plume? A. A submarine trench B. An underwater crater C. A chain of small islands D. A single large mountain 3. A new plate boundary forms in the middle of an ocean. The two plates begin to split apart. Which of these landforms is MOST LIKELY to form as a result? A. A high underwater mountain range that runs along the center of the boundary B. A submarine trench running along the boundary C. Underwater mountain ranges on either side of the boundary D. Midocean ridges on either side of the boundary 4. A large volcanic eruption can produce a cloud of ash that can impact the world's climate for some time. A cloud of ash that blocked out the sun for four months would MOST LIKELY have which of these effects? A. Higher temperatures on Earth and increased rates of photosynthesis B. Large amounts of precipitation and flooding of coastal areas C. Lower temperatures and slower rates of plant growth D. High rates of extinction among reptiles and amphibians 5. How could the formation of the giant continent Pangaea have caused the extinction of many forms of marine life? A. Glaciers formed B. Mountains formed C. Oceans closed up D. Water levels rose 6. A geologist s logbook contained the following observations: The corresponding rock layers on either side of the formation are the same age The ocean floor is wider now than in the past. There is evidence of recent volcanic activity. What type of formation is the geologist studying? A. a midocean ridge B. a trench C. island D. coral reef Page: 1 Unpublished Work, Copyright , Education Service Center Region 10. All Rights Reserved. GO ON

The diagram shows forces acting on rock layers. What landform will result from these actions? A. fault B. mountain C. valley D. volcano 9. The movement of continents is ongoing. What does this movement cause? A. periodic flooding along river valleys B. erosion of mountain peaks C. formation of mountains D. succession of species on volcanic islands 10. Which of these events is most likely to contribute to the extinction of a species of an insecteating bird found only on a large isolated volcanic island? A. Lava from the volcano covering parts of the island with hard sharp lava rock. B. People arriving on the island to study the effects of the volcano on animals. C. A volcanic eruption covering the island with a threefoot layer of volcanic ash. D. Sulfur compounds polluting the prevailing westerly winds passing over the volcano. 11. Many mountains in the Western United States were formed by volcanic activity. Over time, the movement of water changed the form of some of the rocks originally created when the magma hardened. The changing of the volcanic rock by water is the process of A. Erosion B. Sedimentation C. Metamorphosis D. Compaction 12. A volcanic eruption adds, among other things, a large amount of lava to the environment. This balances which of the following forces? A. gravity B. weathering C. erosion D. fossilization 13. Which of these is returned to a stable and balanced state by a volcanic eruption? A. Temperatures in nearby areas B. Gas levels in the atmosphere C. Mineral composition of rock D. Underground pressure levels Page: 2 Unpublished Work, Copyright , Education Service Center Region 10. All Rights Reserved. GO ON

4 TEKS Check Plate Tectonics, Earthquakes and Volcanoes 14. A volcanic eruption covers a wide area of forest with ash, lava, and volcanic rock. Which of these describes the first stage of ecological succession that will begin to return biotic factors back to the forest community and return it to a state of equilibrium? A. The volcano stops erupting. B. The lava cools to form rock. C. Lichens grow on the rocks. D. The rocks melt back into lava. 15. In the early 1900s, Alfred Wegener proposed the theory of continental drift. This theory stated that in Earth's past all of the continents were joined into one supercontinent that broke apart into the continents of today. Since that time, the continents have drifted to their present locations and continue to drift. To which of the following scientific topics has the theory of continental drift contributed the MOST scientific understanding? 17. 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? A. Inner core B. Outer core C. Mantle D. Crust 18. The images below show the same mountain on May 17, 1980, and again on May 18, A. soil composition B. river formation C. plate tectonics D. world climate 16. In 1815, tropical volcano Tambora erupted, sending tons of ash and dust into the atmosphere. The following year, 1816, was known in parts of Europe and North America as "the year without a summer." Which of the following would be an immediate effect of an eruption like Tambora's? A. Heat from the eruption would melt ice caps, causing sea levels to rise. B. Ash would absorb all water vapor in the air, leading to long droughts. C. Heat from the eruption would radiate, heating climates worldwide. D. Ash would block some sunlight, causing evaporation to decrease. Which of the following forces MOST LIKELY caused the changes in the mountain that are shown in the pictures? A. chemical weathering B. glacial erosion C. volcanic eruption D. crustal uplift Page: 3 Unpublished Work, Copyright , Education Service Center Region 10. All Rights Reserved. GO ON

Mountain ranges TEKS Check Plate Tectonics, Earthquakes and Volcanoes 20. The map above shows three mountain ranges in the United States. Which of the following forces caused these mountain ranges to form? A. Glacial drift B. Volcanic eruption C. Physical weathering D.
