Across
- 4. downhill movement of weathered material
- 6. fall of a large mass of earth, rock, or snow
- 7. oxidation reactions are chemical weathering processes where rock-forming minerals react with oxygen, often in the presence of water
- 8. thick masses of permanent ice found on land that slowly move
- 11. abrasion the process of scraping or wearing something away
- 12. ice wedging form of mechanical weathering where water seeps into cracks
- 13. mass of rock and soil slips in one big chunk
- 15. type of physical weathering where salt crystals grow within cracks in rocks
- 17. unconsolidated mineral or organic material on the immediate surface of the Earth
- 19. the process when soil and sediment get frozen under a glacier
- 20. rain and snowmelt moving over Earth’s surface
- 21. process where thin, curved layers of rock detach from the surface of the rock due to weathering
- 22. form of mechanical weathering where plant roots grow into cracks in rocks
- 23. type of physical weathering where rocks break down due to the repeated expansion and contraction caused by temperature changes
Down
- 1. defined as the uppermost layer of natural soil
- 2. pore spaces are filled with water and air
- 3. study of the solid rock foundation beneath the Earth's surface
- 4. process by which minerals in rocks are broken down and changed into new minerals and substances
- 5. disintegration of rocks and minerals by the activities of living organisms
- 8. large scratches left by glaciers
- 9. grooves or scratches on bedrock surfaces
- 10. stable, dark-colored organic matter found in soil
- 14. downslope movement of rock, soil, and debris under the influence of gravity
- 16. downward movement of water saturated soil
- 18. sediment the deposits after the glacier retreats
