  1. rock that forms when molten material cools and solidifies either inside Earth or at the surface
    igneous
  2. a mixture of molten rock and gases, including water vapor, which forms underground
    magma
  3. magma that flows out of volcanos
    lava
  4. small, solid pieces of material that comes from rock or living organisms
    sediment
  5. rock that forms over time as a sediment is squeezed and cemented together
    sedimentary rock
  6. sedimentary rock that form fromt eh broken fragments of other rocks are called
    clastic rocks
  7. form when minerals preceipitate out of solution
    chemical rock
  8. marine life extract calcium carbonate from ocean water to form their shells and skeletons, this process is a form of
    organic rock
  9. most common sedimentary rock
    organic limestone
  10. clastic rocks are classified mainly based upon the ________
    average size of the fragments that they contain
  11. what does the process of weathering break down?
    • rock at Earth's surface, turning it into smaller pieces.
    • ex. wind rain ice
  12. sedimentary; contains clay particles (compressed and sometimes cementer) clastic
    shale
  13. light color; felsic; coarse texture; intrusive; igneous
    granite
  14. metamorphic; foliated; microscopic mica grains; regional
    slate
  15. mostly carbon from plants of million of years ago; black, crumbly, low density; found between layers of sediment; organic; sedimentary
    coal
  16. metamorphic; foliated (medium) mica grains; quartz; regional
    schist
  17. metamorphic; foliated (thick) contains feldspar, mica, quartz; light and dark colored bands; regional
    gneiss
  18. non-foliated; calcium carbonate; high density; highly crystalline; metamorphic; regional or contact
    marble
  19. sedimentary; contains calcite; some clay; may contain fossils; chemical
    limestone
  20. igneous; dark color; mafic; fine texture; extrusive
    basalt
  21. sedimentary; composed mostly of sand grains (quartz) cemented together w/ iron oxide; stratification; porous; clastic
    sandstone
  22. intense heat and pressure ctreated over large areas during montain building
    regional
  23. intense heat from magma "bakes" surrounding rock, limited to ~ .6 mi.
    contact
  24. rock that hasbeen changed by temperature, pressure, or reactions with hot water
    metamorphic
  25. forms when a rock is transformed by heat, pressure, or chemical reactions; form under high temperatures and pressures deep underground
    metamorphic rock
  26. crystals arranged in parallel layers or bands
    foliated rocks
  27. series of processes in which rocks continuously change from one type to another
    rock cycle
  28. mineral that fractures; hardest common mineral, continental rock contain
    quartz
  29. mineral with 2-way cleavage at 90 degrees; most common mineral in Earth's crust
    feldspar
  30. 1-way cleavage, peels off thin elastic sheets, common in granite
    mica
  31. softest mineral on Moh's scale
    talc
