Across
  1. 5. movement the downhill movement of rock and soil because of gravity
  2. 7. a slide of a large mass of dirt and rock down a mountain or cliff
  3. 12. A mixture in which particles can be seen and easily separated by settling or filtration
  4. 14. a very fine-grained soil that is plastic when moist but hard when fired (less than .0004 cm)
  5. 15. scratches left on rocks and bedrock by glacier movement
  6. 19. a mechanical weathering process which removes protruding overlying layers and exposes the weathered down dome of the underlying layers. Exfoliation releases pressure from the removal of overlying rocks.
  7. 20. Lakes a body of water that forms in a long narrow U-shaped glacial valley often partly dammed at one end by a mound of glacial moraine sediment example the Finger lakes of NY
  8. 22. a ridge of sand created by the wind
  9. 23. small particles of various minerals and broken rocks, he result of weathering and erosion (.006-.02 cm)
  10. 25. carbonic acid reacts with calcite to dissolve limestone or dolostone
  11. 27. left over; remaining
  12. 29. small rocks sometimes called gravel (.2-6.4 cm)
  13. 31. carried from one place to another
  14. 32. a complex mixture of weathered mineral materials from rocks, partially decomposed organic molecules, and a host of living organisms
  15. 33. weathering the process in which rock is broken down by changes in its chemical makeup
  16. 35. An unsorted and unstratified accumulation of glacial sediment, deposited directly by a glacier
  17. 36. matter the remains of plants and animals
  18. 38. things (bugs, worms,plant roots)
  19. 39. most frequent or common; significant or important
  20. 40. a long mound of till that is smoothed in the direction of the glacier's flow
Down
  1. 1. soil by the work of
  2. 2. lake forms when a depression left in till by melting ice fills with water
  3. 3. the process of moving sediment from one place to another
  4. 4. profile a vertical section of soil from the ground surface to the parent rock
  5. 6. rocks (25 cm or larger)
  6. 8. The volume of water a river transports over a given amount of time.
  7. 9. weathering weathering that changes the shape and size of rocks without changing the chemical makeup of the rock
  8. 10. speed
  9. 11. a slowly moving mass of ice
  10. 13. a chemical change in which a substance combines with oxygen, as when iron oxidizes, forming rust
  11. 16. horizon a layer in a soil profile
  12. 17. a mixture of tiny bits of soil and rock carried and deposited by a river (.0004-.006 cm)
  13. 18. rounded stones about he size of sandwich rolls (6-25 cm)
  14. 21. plain flat area in front of a glacier where the debris washes out with the meltwater at the end of a glacier
  15. 24. large, rounded or
  16. 25. a steep high face of rock
  17. 26. The breaking down of rocks and other materials on the Earth's surface
  18. 28. the process of combining with water
  19. 29. action plant roots grow in the cracks of rocks and gradually push them apart
  20. 30. a mixture in which one substance is dissolved in another
  21. 34. flow rapid movement of flowing mud
  22. 37. activity breaking down of rocks and
