Across
  1. 2. the theory that the continents were once joined and then slowly drifted apart.
  2. 3. the part of the Earth where life exists
  3. 4. Chemical or physical processes that break down rocks into smaller pieces.
  4. 8. the outer layer of the Earth, a hard rocky shell forming Earth's surface.
  5. 11. a crack or break in Earth's crust.
  6. 14. the innermost layer of the Earth
  7. 16. thick middle layer of the Earth's interior structure consisting of hot rock that is dense but flexible
  8. 18. The process of converting liquid into vapor or gas.
  9. 20. Piles of rocky debris left by melting glaciers.
  10. 22. the water areas of the Earth, including oceans, lakes, rivers, and other bodies of water.
  11. 23. Molten rock that is located below Earth's surface.
  12. 26. the term scientists use to describe the activities of continental drift and magma flow, which create many of Earth's physical features.
  13. 27. Moisture that falls to the Earth as rain, sleet, hail or snow.
  14. 28. The movement of weathered rock and material by wind, glaciers and moving water.
Down
  1. 1. part of a continent that extends out underneath the ocean.
  2. 5. the uppermost layer of Earth that includes the crust, continents and ocean basins.
  3. 6. slow process in which an oceanic plate slides under a continental plate, creating debris that can cause continents to grow outward.
  4. 7. The process of excess water vapor changing into liquid water when warm air cools.
  5. 9. process by which magma wells up between oceanic plates and pushes the plates apart.
  6. 10. Process of cracking that occurs when the folded land cannot be bent any further.
  7. 12. a thin layer of gases that surrounds the Earth.
  8. 13. Water located underground within the Earth that supplies wells and springs.
  9. 15. The regular movement of Earth's water from ocean to air to ground and back to the Ocean.
  10. 17. Process by which oceanic plates dive beneath continental plates often causing mountains to form on land.
  11. 19. The removal of salt form seawater to make it usable for drinking and farming.
  12. 21. A large body of ice that moves across the surface of the Earth.
  13. 24. Underground water bearing layers of porous rock, sand and gravel.
  14. 25. a bend in layers of rock, sometimes caused by plate movement.
