Across
- 3. the breaking down of rocks
- 6. process in which large flat or curved sheets of rock fracture and are detached from the outcrop due to pressure release
- 7. occurs when runoff water forms small channels as it concentrates down a slope
- 9. a vertical cross-section of the soil, made of layers running parallel to the surface
- 11. weathered soil deposits that are transported from one place to another
- 14. a layer parallel to the soil surface whose physical, chemical and biological characteristics differ from the layers above and beneath
- 15. the erosion of rocks formed by chemical reactions
Down
- 1. a soil material which is the result of weathering and decomposition of rocks
- 2. surface minerals
- 4. causes rocks to crumble due to physical strain
- 5. the process of wearing or being worn due to the atmosphere
- 8. chemical reaction formed by making contact with oxygen
- 10. the laying down of sediment by wind, water, or ice.
