                                                   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
