Across
- 2. A mass of material deposited in a triangular or fan shape at the mouth of a river or stream
- 3. A mass of rocks and sediment carried down and deposited by a glacier
- 6. The process by which wind, water, ice, or gravity transports soil and sediment from one location to another
- 7. The process in which material is laid down
- 9. Fan-shaped mass of material deposited by a stream, when the slope of the land decreases sharply.
- 11. Collective erm for several mechanical weathering processes induced by stresses created by the freezing of water to ice
- 14. A mound or ridge of sand or other loose sediment formed by the wind.
- 15. The chemical breakdown and decomposition of rocks by natural processes in the environment.
- 17. Thick sheets of ice that may spread over large areas, like whole continents
- 20. The natural process by which atmospheric and environmental agents, such as wind, rain, and temperature changes, disintegrate and decompose rocks
- 21. The sudden movement of rock and soil down a slope
- 22. Quality of being porous
Down
- 1. A large mass of ice that exists year-round and moves over land
- 4. An area along a river that forms from sediments deposited when the river overflows it’s banks
- 5. The mechanical breakdown of rocks into smaller pieces that is caused by natural processes and that does not change the chemical composition of rock material
- 8. The chemical reaction in which a material combines with oxygen to form another material
- 10. the same thing of another weathering
- 12. The flow of mud or rock and soil mixed with a large amount of water
- 13. A glacier the forms in a mountainous area
- 16. The rock material carried and deposited by glaciers
- 18. The process of which a rock is reduced in size by the scraping action of other rocks driven by water, wind, and gravity.
- 19. precipitation Rain, sleet, or snow, that contains a high concentration of acids.
