  1. 5. A type of rock formed when magma or lava cools and hardens.
  2. 7. Type of weathering that breakdown of rock through chemical reactions that change its minerals.
  3. 9. The places where two tectonic plates meet.
  4. 10. Melted rock found beneath Earth's surface.
  5. 12. The liquid layer of iron and nickel surrounding the inner core.
  6. 13. Large pieces of Earth's lithosphere that move slowly over time.
  7. 15. A naturally occurring, nonliving solid with a specific chemical composition and crystal structure.
  8. 18. The process in which pressure squeezes sediment particles closer together.
  9. 19. Thick, dense layer of Earth's crust beneath the continents.
  10. 22. Type of weathering that breakdown of rock into smaller pieces without changing its chemical composition.
  11. 24. The scientist who proposed the theory of continental drift.
  12. 26. A Boundary place where two tectonic plates move toward each other.
  13. 27. The process in which transported sediment is dropped in a new location.
  14. 28. A type of rock formed when sediments are compacted and cemented together.
  15. 29. The circular movement of material caused by differences in temperature and density.

  1. 1. The process in which dissolved minerals glue sediment particles together.
  2. 2. The process of breaking rocks into smaller pieces.
  3. 3. The thin, dense layer of Earth's crust beneath the oceans.
  4. 4. Small pieces of rock, minerals, and other materials.
  5. 6. Earth's solid, extremely hot center, made mostly of iron and nickel.
  6. 8. The movement of sediment by water, wind, ice, or gravity.
  7. 10. A type of rock changed by heat and pressure without melting.
  8. 11. The thick layer of hot rock between Earth's crust and core.
  9. 14. A boundary place where two tectonic plates slide past each other.
  10. 16. The theory that continents slowly move across Earth's surface.
  11. 17. The continuous process by which rocks change from one type to another.
  12. 20. The soft, slowly flowing layer of the upper mantle beneath the lithosphere.
  13. 21. A Boundary place where two tectonic plates move away from each other.
  14. 23. Earth's rigid outer layer, made of the crust and uppermost mantle.
  15. 25. The ancient supercontinent that once contained nearly all Earth's landmasses.
