Study Guide for Rocks: Mineral Mixtures Test
1. What does it mean if the mineral grains in a metamorphic rock are arranged in
bands? Foliated
2. What is a change in the shape of rock caused by force? Deformation
3. What is a type of metamorphic rock in which the grains are not arranged in planes or
bands? Non-foliated
4. What is a process other than heat that causes metamorphism? Pressure
5. What kind of sedimentary rock is made from solutions of dissolved minerals and
water? Chemical
6. What kind of sedimentary rock is made of fragments of rocks cemented together by a
mineral? Clastic
7. What process forms sediment? Weathering
8. What kind of rock cools at Earth’s surface? Extrusive Igneous Rock
9. What kind of texture does igneous rock have when magma cools rapidly? Finegrained
10. What kind of texture does igneous rock have when magma cools slowly? Coursegrained
11. Define deposition Process in which sediment is dropped and comes to rest
12. Define erosion Process by which sediment is removed from its source
13. Define rock Naturally occurring solid mixture of one or more minerals and organic
matter
14. Define rock cycle Process by which new rock is made from old rock
15. Define composition The chemical makeup of a rock
16. Define extrusive igneous rock Rock that cools at the Earth’s surface
17. Define intrusive igneous rock Rock that cools below the Earth’s surface
18. Define strata Layers found in sedimentary rock
19. Describe two ways rocks were used by early humans and ancient civilizations. Early
humans used rocks as hammers to make other tools. Rock has been used as a
construction material by ancient civilizations.
20. Describe two ways a rock can undergo metamorphism.
1.
Heat and pressure (Contact Metamorphism) – occurs near pockets of magma
2. Pressure (Regional Metamorphism)
21. Study your Rock Cycle diagram that was filled out in class.
Know the three different classes of rock based on the way it was formed: Sedimentary,
Igneous and Metamorphic
