  1. 1. explodes with lava
  2. 2. this type of metamorphic rock forms when mineral grains grow and rearrange, but don't form layers
  3. 3. this type of sedimentary rock forms when dissolved materials come out of solutions
  4. 4. this type of sedimentary rock is made from the remains of once living things
  5. 5. this type of rock is formed because of changes in temperature or pressure
  6. 9. this type of igneous rock forms from magma below the surface of the Earth
  7. 11. nonfoliated rocks do not form these
  8. 12. this type of rock forms when sediments are compacted and cemented together
  9. 13. igneous rock that is very common and sometimes used in construction
  10. 18. this rock type forms when a volcano's magma cools and hardens
