The rock cycle indicates that each type of rock can ____. a. provide materials to make other rocks c. be changed by natural processes b. form other types of rocks d. all of the above ____ 9. Pumice, obsidian, and scoria are kinds of ____. a. granite c. intrusive rocks b. volcanic glass d. andesitic rocks Rock Cycle Review 2 ____ 10. A rock is ____. a. always made of molten material b. a mixture of minerals, organic matter, volcanic glass, or other materials c. a pure mineral d. either igneous or sedimentary ____ 11. The crystals that form in slowly cooling magma are generally ____. a. nonexistent c. tiny b. invisible d. large ____ 12. Sedimentary rocks are ____. a. formed below Earth’s surface as magma b. a type of foliated igneous rock c. formed by great heat d. formed from already existing rocks that are weathered and eroded ____ 13. Andesitic rocks have mineral compositions between those of ____ and basaltic rocks. a. conglomerate c. granitic b. metamorphic d. organic ____ 14. Detrital rocks are ____. a. made of fragments of other rocks b. formed from magma c. precipitated from solution d. all of these ____ 15. Sedimentary rocks are usually classified as ____. a. intrusive or extrusive c. basaltic, granite, or andesitic b. foliated or nonfoliated d. detrital, chemical, or organic Matching Match the terms with their descriptions below. a. granitic b. metamorphic rocks c. rock cycle d. sedimentary rocks e. cementation f. basaltic g. rock h. extrusive i. j. k. l. m. n. o. sediments igneous rocks compaction intrusive foliated lava nonfoliated ____ 16. rocks formed by changes in heat and pressure or the presence of hot, watery fluids ____ 17. rocks formed from molten material ____ 18. rocks formed from sediments ____ 19. igneous rocks formed on or near Earth’s surface Rock Cycle Review 3 ____ 20. layered metamorphic rocks ____ 21. light-colored igneous rocks with a lower density than basaltic rocks ____ 22. dense, dark-colored igneous rocks ____ 23. metamorphic rocks that don’t have layers ____ 24. igneous rocks formed below Earth’s surface ____ 25. model that illustrates the processes that create and change rocks ____ 26. magma that reaches Earth’s surface and flows from volcanoes ____ 27. a mixture of minerals, organic matter, volcanic glass, or other materials ____ 28. process by which sediments are pressed together to form rock ____ 29. process by which large sediments are glued together by dissolved minerals to form rock ____ 30. bits of weathered rock, minerals, grains, plants, and animals that have been eroded Problem Use the following words to fill in the rock cycle diagram below: Metamorphic Sedimentary Igneous Weathering & Erosion Melting Pressure & Heat Rock Cycle Review 4 Describe cementation. How would mineral content be useful in identifying an unknown mineral? What provides the best evidence of the environment an igneous rock was formed? 1) Thickness 2) Size 3) Color 4) Texture What process are necessary to turn an igneous rock into a sedimentary rock? Extrusive rocks have small grains because they cool ________________________________. Sedimentary rocks contain evidence of past life and events called _____________________. What is the most abundant compound found in magma? Not all parts of magma melt at the same temperature or at the same time. This concept is known as ____________________________ __________________________. Rocks are generally classified into three groups according to their a) Mineral content b) Size c) Color d) Origin Another name for the layered appearance of metamorphic rocks is _________________________________. Rock Cycle Review 5 38. Use these words to fill in the blanks. Physical & chemical properties Where they are formed Extrusive Composition Intrusive Granitic Basaltic Andesitic Crystal size Composition determines Igneous Rocks Can be classified two ways. Where they are formed de termines Rock Cycle Review 6 39.. Directions: Use the following terms: layers foliated nonfoliated Have Metamorphic Rocks are classified two ways Do Not Have 41.Use the following words to complete the chart: Organic Detrital Chemical Halite Coal Weathering Compaction Cementation Erosion Dissolved Minerals in Solution Made of the remains of once living things Broken fragments of other rocks If sediments have large pieces then this occurs 1 If sediments have small pieces then this occurs made from These are created by and then moved by Sedimentary Rocks are classified in 3 ways 2 formed from Example 3 Example
