1 TEST THE FOURTH Rocks, Minerals The Rock Cycle and “The test is to recognize the mistake, admit it and correct it. To have tried to do something and failed is vastly better than to have tried to do nothing and succeeded.”Dale E. Turner"Experience is a hard teacher because she gives the test first, the lesson afterward."Vernon Law"A liberally educated person meets new ideas with curiosity and fascination. An illiberally educated person meets new ideas with fear.“James B. StockdaleTuesday, February 24th, 2009
2 TEST THE FOURTH: ROCKS, MINERALS AND THE ROCK CYCLE Name ________________________________________________ Date ______________ Period _______TEST THE FOURTH: ROCKS, MINERALS AND THE ROCK CYCLEDirections: This test is designed to let your teacher know how much information you have learned over the past few weeks, and to allow you to gauge this as well. Remember to think about your notes, and all the examples and demonstrations that we’ve done in class. Read each question carefully and completely before making your response, and make sure that whatever you write answers every part of the question. Do not leave any blank questions or naked numbers. Blank questions will be marked off at twice the rate of a wrong answer. Relax, good luck, and enjoy!0. What happens when an unstoppable force meets an immovable object?1. What are rocks made out of?A. Cheese B. Other, smaller rocks C. Minerals D. More cheese _________2. What is one way that igneous rocks can be classified?A. Temperature B. Iron or Aluminum content C. Acidity D. Reactivity _________3. An igneous rock contains very coarse crystals, and is made mostly of quarts and potassium feldspar. What is the identity of the rock?4. Could fluorite scratch talc? EXPLAIN your answer for full credit.5. Which sedimentary rock is formed from the smallest sediments?A. Shale B. Sandstone C. Conglomerate D. Gneiss _________6. Given the hardness chart to starboard and what you know about minerals, which of the following statements is true?A. A fingernail will scratch calcite but not gypsum.B. Calcite will be scratched by a copper penny.C. The mineral apatite will scratch topaz.D. A steel file has a hardness of about 7.5._________
3 7. Which type of rock was chemically weathered by acidic groundwater to produce the cave and its features?8. According to the ESRT, if a metamorphic rock is melted, what does it turn into?9. According to the ESRT, name at least two processes that can result in the formation of sedimentary rocks.10. The rock marble most likely started out as which type of rock?A. Limestone B. Shale C. Schist D. Pegmatite _________11. Which mineral has a metallic luster, a black streak, and is an ore of iron?A. Galena B. Pyroxene C. Magnetite D. Graphite _________12. In which set of pictures are the rocks correctly labeled?13. A student used a single characteristic to classify six minerals into two groups, A and B. Which characteristic was used to group them?A. siltstone B. quartziteC. basalt D. Limestone _________A. 1B. 2C. 3D. 4_________A. ColorB. LusterC. Chemical compositionD. Hardness_________
4 14. Dolostone is classified as which type of rock? A. Land-derived sedimentary rockB. Chemically formed sedimentary rockC. Foliated metamorphic rockD. Nonfoliated metamorphic rock _________15. Quartz and halite have different crystal shapesprimarily becauseA. Light reflects from crystal surfaceB. Energy is released during crystallizationC. Of impurities that produce surface variationsD. Of the internal arrangement of the atoms _________16. Explain the difference between intrusive and extrusive rocks. You may write, draw or both.17. How can a sedimentary rock be turned into a metamorphic rock?18. Stuart charted the crystal size of some igneous rocks as compared to their cooling time. Create a graph of his findings on the grid below. BE SURE to include all the necessary parts of your graph!Crystal Size1 mm3 mm6 mm10 mm14 mmCooling Time5 minutes20 minutes30 minutes60 minutes100 minutesCooling Time (min)
5 19. Based on the results of your graph, what happens to crystal size as cooling time gets BIGGER? 20. What kind of relationship is demonstrated in your graph?21. What happens to the density of a rock as it is metamorphosed?23. Which diagram represents a landscape where fine-grained igneous bedrock is most likely to be found?24. A student obtains a cup of quartz sand from a beach. A saltwater solution is poured into the sand and allowed to evaporate. The mineral residue from the saltwater solution cements the sand grains together, forming a material that is most similar in origin toA. An extrusive igneous rock B. An intrusive igneous rockC. A clastic sedimentary rock D. A foliated metamorphic rock _________Thee chart to starboard shows the conditions in the Earth’s crust under which three minerals, all with the same chemical composition, will form.25. Under which crustal temperature and pressureconditions will andalusite form?A °C and 6000 atmospheresB. 600°C and 4000 atmospheresC. 500°C and 2000 atmospheresD. 700°C and 8000 atmospheresA. 1B. 2C. 3D __________________
6 26. Which mineral has a chemical composition most similar to andalusite, sillimanite, and kyanite?A. Pyrite B. Dolomite C. Gypsum D. Potassium feldspar _________27. If bedrock at a collisional plate boundary contains andalusite crystals, these crystals are changed into sillimanite and/or kyanite as temperature and pressure conditions increase.What is this process called?A. Weathering B. Metamorphism C. Solidification D. Cementation _________28. Why is the landscape in some areas of New York different from the landscape in other areas?29. In the space below, indicate at least three things that could happen to a sedimentary rock to change it. You may write, draw, or both.
