Across
  1. 2. A rock that forms from compressed or cemented layers of sediment
  2. 4. When one plate slips under the other due to differences in their density
  3. 9. Rock that has been changed by heat and pressure
  4. 11. A physical feature on Earth's surface (ex: mountains or canyons)
  5. 13. Sections of the crust located under the oceans and seas... usually younger than other sections of crust, and made mostly of basalt
  6. 14. Boundary that occurs where plates slide PAST each other... causes earthquakes
  7. 18. Process in which eroded material (sediment) is laid down in new locations
  8. 22. The layer of hot, semi-solid material between Earth's crust and core.
  9. 23. Not formed from living things or the remains of living things
  10. 24. Molten rock beneath the earth's surface
  11. 26. The layer of rock that forms Earth's outer surface.
  12. 27. A type of fuel that forms from the ancient remains of decomposed plants and animals (2 words)
  13. 29. Boundary that occurs where two plates slide TOWARD each other... forms mountains and volcanoes
  14. 31. A German scientist who proposed the theory of continental drift (2 words)
  15. 34. The color of a mineral in powdered form... found by rubbing the mineral on an unglazed porcelain plate
  16. 35. The formation of new crust at an ocean-ocean divergent boundary, as a result of magma pushing upward and outward from Earth's mantle to the surface (2 words)
Down
  1. 1. The location where two tectonic plates meet. (2 words)
  2. 3. Sections of the crust that form landmasses... tend to be older than other sections of the crust, and made mostly of granite
  3. 5. Igneous rock that forms when magma rises up and cools in a place underground (2 words)
  4. 6. Processes by which rock, sand, and soil are broken down and carried away due to weathering
  5. 7. The process of rock being broken down by abrasion (ex: different types of weather, moving air, water, sand, glaciers, ice formation, etc.) (2 words)
  6. 8. A dense sphere of solid iron and nickel at the center of Earth (2 words)
  7. 10. A scale ranking minerals from 1 (softest) to 10 (hardest) (3 words)
  8. 12. The process that breaks down or dissolves rock through chemical reactions (ex: acid in geothermal areas, oxidation, etc.) (2 words)
  9. 15. The process in which rocks are created, changed, destroyed, and formed again (2 words)
  10. 16. A naturally occurring, inorganic solid that has a definite chemical composition and an orderly arrangement of atoms
  11. 17. When weight from layers of sediment forces out fluids and air, decreasing the space between sediments
  12. 19. Rock that forms when magma cools above the surface of Earth, usually as a result of a volcano... sometimes has holes from escaping gas (2 words)
  13. 20. The gradual movement of the continents across the earth's surface (2 words)
  14. 21. Magma that reaches Earth's surface
  15. 25. Sections of the Earth's crust that move due to convection currents. (2 words)
  16. 28. A layer of molten iron and nickel that surrounds the inner core of Earth (2 words)
  17. 30. Boundary that occurs where two plates slide AWAY from each other... forms valleys and sea-floor spreading
  18. 32. The way a mineral reflects light
  19. 33. The hardest known mineral
