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