  1. Chapter 3 - Rocks Test Wednesday

  2. Which of following is not one of the three classes of rocks? • Igneous • Metamorphic • Magma

  3. What two processes change rock into sediments? • Cooling & Hardening • Heat & Pressure • Weathering & Erosion

  4. What two things can change sedimentary and igneous rocks into metamorphic rocks? • Cooling & Hardening • Heat & Pressure • Weathering & Erosion

  5. What is the only kind of rock that can form directly from magma? • Igneous • Metamorphic • Sedimentary

  6. All rocks are made up of • Lava • Sediments • Magma • Minerals

  7. The grouping of things that are alike is the science of • Petrology • Classification • Geology • Biology

  8. Rocks formed when melted minerals cool and harden are classified as • Molten rocks • Sedimentary rocks • Igneous Rocks • Lava Rocks

  9. Magma that reaches Earth’s surface is called • Lava • Molten • Igneous • Conglomerate

  10. Molten rock is made up of • Melted minerals • Lava • Obsidian • Iron and Nickel

  11. The mineral crystals of a rock formed from magma usually are • Small • Large • Fine • Cubic

  12. Rocks formed from the remains of living things are classified as • Metamorphic • Igneous • Sedimentary • Lava

  13. Limestone and halite are examples of • Clastics • Nonclastics • Foliated • Nonfoliated

  14. A rock formed when another rock is changed by heat and pressure is classified as • Metamorphic • Igneous • Sediment • Clastic

  15. The series of natural processes by which rocks are slowly changed from one type to another is • Sedimentation • The Rock Cycle • Classification • Petrology

  16. A metamorphic rock that has mineral crystals arranged in bands is • Unfoliated • Foliated • Clastic • Nonclastic

  17. The texture of an igneous rock that does NOT have mineral crystals is • Fine • Clastic • Glassy • Foliated

  18. Quartzite is formed from • Halite • Sandstone • Shale • Pyrite

  19. Coal is a sedimentary rock formed from • Lava • Plants • Chemicals • Magma

  20. Two minerals commonly found in igneous rocks are mica and • Halite • Feldspar • Pyrite • Silver
