Name: ________________________________ Rocks Study Guide 1. In the rock cycle, how would metamorphic rock become magma? It would melt 2. Describe a pathway through the rock cycle Cools forming Igneous rock. Its weathered and eroded into sediments. The in which magma becomes sedimentary rock. sediments are compacted and cemented forming sedimentary rock. 3. In general, what are rocks made of? Minerals and other things 4. Where does the heat that changes a rock into metamorphic rock from? The mantle 5. What is the name of sedimentary rock that is made up of rounded fragments? Conglomerate 6. What step in the rock cycle would be Weathering and Erosion followed by compaction and required to change granite into sandstone? cementation 7. How do geologists Arrangement of the grains classify metamorphic rock? 8. When forces inside Earth push rock down towards the mantle, Metamorphic what kind of rock would form? 9. What step in the rock cycle helps sedimentary rock to form? Compaction and cementation 10. Why would sedimentary rock have to It would have to be pushed into the mantle and the pressure and heat of that become metamorphic rock before it becomes process would change it into metamorphic rock. When its pushed deep enough it would melt into magma magma? 11. What two pathways in the rock cycle could Directly to metamorphic with heat and pressure or igneous rock take to become metamorphic become sedimentary rock first then metamorphic. roc,? 12. Can metamorphic rock that is nonfoliated split into layers? No 13. What is the term used to describe metamorphic rock that has grains arranged Foliated in parallel layers? 14. How do geologists classify metamorphic Arrangement of the grains rock? 15. What type or types of rock can change into sedimentary rock? All types 16. What do we call the series of processes on Earth’s surface and its The Rock Cycle interior that changes rock from one kind to another? 17. What do we call the texture of an igneous rock that has large crystals Porphritic scattered on a background of smaller crystals? 18. Where does most metamorphic rock form? Deep inside the Earth 19. What term is used to describe the texture of a rock whose grains are Course-grained large and easy to see? 20. What type of igneous rock forms from lava that erupts onto Earth’s Extrusive Igneous Rock surface? 21, What type of igneous rock forms when magma cools below Earth’s Intrusive Igneous Rock surface? 22. What do geologists look at when they want Size and shape of the grains to describe a rock’s texture? 23. In the rock cycle, what happens to lava and magma once they cool and Forms igneous rock harden? 24. What do we call the texture of an igneous rock whose grains Fine-grained are hard to see? 25. Label the process involved in the rock cycle that change one type of rock into another. Match the above rocks with the correct rock from the following list: slate, breccia, granite, limestone, conglomerate, gneiss. Classify the rock into one of the three major rock groups and explain how it formed. Rock Name Rock Type How did it form Rock A. Cooling of magma Granite Igneous Rock B. Heat and pressure on an existing rock (granite) Gneise Metamorphic Rock C. Weather and Erosion of existing rock forming sediments which are Conglomerate Sedimentary then compacted and cemented together. Rock D. Weather and Erosion of existing rock forming sediments which are Breccia Sedimentary then compacted and cemented together Rock E. Limestone Sedimentary Shells of dead animals cemented together Rock F. Heat and pressure exerted on existing rock (shale) Slate Metamorphic .
