Name: ____________________________ pd. ______ Seat #_____ Color _____________ Chapter 5 & 6 >> Study Guide - Rocks 1. Name the three types of rocks studied in this chapter and describe how each is formed. Give an example of each. a. b. c. 2. How is the formation of sandstone, rock salt, and coal similar? How is their formation different? 3. Why does obsidian have a glassy texture? Why doesn’t gabbro? 4. How and why is the appearance of conglomerate different from granite? 5. What is the rock cycle? Draw &/or describe it. 6. Identify the sequence of processes that form sedimentary rock. 7. Compare & contrast rocks and minerals. (do not just give a definition of each) 1) Match each phrase with the word that best fits. Write the letter in the blank. 2) After each vocab word, write the rock type that is best associated with that term I=igneous S=sedimentary M=metamorphic _____ 1. Granite is an example of this type of rock composition A. felsic _____ _____ 2. The process in which sediments are glued together B. cementation _____ _____ 3. Sedimentary rocks formed from solutions of chemicals in water C. chemical _____ _____ 4. Sedimentary rocks formed from fragments of other rocks D. clastic _____ _____ 5. To make smaller, more dense E. compaction _____ _____ 6. The process by which sediment settles out of water F. deposition _____ _____ 7. Molten material underground G. igneous rock _____ _____ 8. The process in which water or wind carry away sediments H. erosion _____ _____ 9. The visible layering in sedimentary rocks I. extrusive _____ _____ 10. Minerals are not aligned in a metamorphic rock J. foliated _____ _____ 11. Type of igneous rock formed below ground K. intrusive _____ _____ 12. Molten material on the Earth’s surface L. Weathering _____ _____ 13. Dark colored igneous rocks M. mafic _____ _____ 14. Rocks formed from molten material N. magma _____ _____ 15. Texture in which minerals align O. marble _____ _____ 16. Rock with sugary appearance that should fizz when acid added P. nonfoliated _____ _____ 17. Sedimentary rocks formed from once living materials Q. organic _____ _____ 18. Type of igneous rock formed above ground R. stratification _____ _____ 19. The breaking down of rocks, either mechanically or chemically S. lava _____ 21.
