Weathering, Erosion, Deposition and Soil
Across
- 1. a land form created by rivers
- 3. the amorphous, ordinarily dark colored, colloidal matter in soil; a complex of the fractions of organic matter of plant, animal, and microbial origin that are most resistant to decomposition
- 6. the upper layer of soil
- 11. Rain acid precipitation falling as rain
- 12. Wedging a collective term for several mechanical weathering processes induced by stresses created by the freezing of water into ice
- 15. Dune a hill of sand near an ocean or in a desert that is formed by the wind
- 17. a slowly moving mass or river of ice formed by the accumulation and compaction of snow on mountains or near the poles
- 19. the state or process of rotting
- 21. a large natural stream of water flowing in a channel to the sea, a lake, or another such stream
- 22. Movement the movement downslope of rock fragments and soil under the influence of gravity
- 23. the process of wearing down or rubbing away by means of friction
Down
- 2. a group of natural processes, including weathering, dissolution, abrasion, corrosion, and transportation, by which material is worn away from the Earth's surface
- 4. Weathering any of the destructive effects of the atmosphere and the exposure of rocks to the extremes of the surface
- 5. Composition what soil is made of
- 7. the absorption by a mineral of one or more oxygen ions. The major type of chemical weathering, particularly in rocks containing iron
- 8. solid material that is moved and deposited in a new location
- 9. the sliding down of a mass of earth or rock from a mountain or cliff.
- 10. any of the chemical or mechanical processes by which rocks exposed to the weather undergo changes in character and break down
- 13. the absorption by a mineral of one or more oxygen ions. The major type of chemical weathering, particularly in rocks containing iron
- 14. Island a constantly changing deposit of sand that forms parallel to the coast
- 16. the dropping of material which has been picked up and transported by wind, water, or ice
- 18. Weathering chemical effects of water, carbon dioxide, and oxygen attacking and destroying the minerals that are near the surface of the Earth
- 20. a type of wetland, an area of land where water covers ground for long periods of time
