Erosion and Soil

4. A sedimentary ridge or surface formed by glacial till after a glacier melts or retreats.
5. A thick deposit of fine, windblown dust and silt that provides an excellent base for rich soil
6. Sediments deposited by a glacier
7. the process by which factors or conditions in the environment break rocks down into smaller pieces
9. the rapid downward movement of earth material.
12. The process by which wind-driven sand erodes exposed rock. this process is similar to artificial sand blasting
13. A relatively uniform layer of soil

1. a mechanical weathering process in which changes in temperature or the removal of the wight of overlying rock breaks down thin layers or slabs of rock.
2. the process of wearing away rock and transporting sediments
3. the action of wind over a large area to remove small clastic particles, leaving behind cobbles and larger rocks that form desert pavement
8. An especially fertile topsoil containing about 40% sand, 40% silt and 20% clay
10. Layers of eroded earth materials and organic matter (humus) on earth's surface.
11. A depositional landform that results from wind deposited sand and soil.
