Across
  1. 2. igneous rock that cools quickly on Earth’s surface
  2. 3. rock formed when heat and pressure change existing rock
  3. 5. preserved remains or traces of ancient life
  4. 7. process of sediments being dropped in a new location
  5. 11. rock formed from sediments compacted and cemented together
  6. 12. smooth, flat way a mineral breaks
  7. 13. molten rock beneath Earth’s surface
  8. 14. structure repeating pattern of atoms in a mineral
  9. 17. naturally occurring, inorganic substances that make up rocks
  10. 19. reaction fizzing or bubbling of some rocks, like limestone, when acid is applied
  11. 21. movement of sediments from one place to another
  12. 22. jagged or uneven way a mineral breaks
  13. 24. amount of space an object takes up
  14. 25. mass of a substance divided by its volume
  15. 26. age the exact age of a rock or fossil in years
  16. 29. cycle continuous process that changes rocks from one type to another
  17. 30. process that presses sediments together
  18. 31. measured by Moh’s scale to show how easily a mineral can be scratched
Down
  1. 1. small pieces of rock, shell, or organic material
  2. 4. rock formed from cooling and solidification of magma or lava
  3. 6. igneous rock that cools slowly beneath Earth’s surface
  4. 8. process that glues sediments into solid rock
  5. 9. how light reflects from a mineral’s surface
  6. 10. age compares if one rock or fossil is older or younger than another
  7. 15. molten rock on Earth’s surface
  8. 16. horizontal layers of rock that show Earth’s history
  9. 18. color of a mineral’s powder when rubbed on a plate
  10. 20. fossils fossils from organisms that lived a short time but were widespread
  11. 23. amount of matter in an object
  12. 27. of superposition principle stating the oldest rock layers are at the bottom
  13. 28. breaking down of rocks into smaller pieces
  14. 29. solid mixtures of minerals that form Earth’s crust
