  1. 2. Composition of dark-colored igneous rocks
  2. 6. Weathering that occurs to carbonate rocks, such as limestone, in which the rock is dissolved
  3. 8. The description of metamorphic rocks when they contain layers
  4. 10. How much variety there is in grain size in sedimentary rocks
  5. 11. The type of age dating that dates rocks based off isotopes in the rock
  6. 12. Local sea water rising relative to where it was previously
  7. 16. The type of age dating that compares the ages of rocks based off their sequence; not an exact age
  8. 18. A type of weathering AND a type of sedimentary rock

Down
  1. 1. A type of weathering in which large changes in temperature cause rock layers to “peel” off
  2. 3. Very small or fine crystal size in igneous rocks
  3. 4. A type of weathering in which wind or water rubs against rocks enough to smooth them out
