1. Erosion Four Corners Last man standing! (most likely going to be a woman… Just saying…)

2. When rill erosion is not controlled, the MAIN result is: 1-Aseptic erosion. 2-Glacial erosion. 3-Gully erosion. 4-Sheet erosion.

3. When topsoil is removed at an excessive rate, usually caused by humans, it is BEST called: 1-Accelerated erosion. 2-Glacial erosion. 3-Natural erosion. 4-Shore erosion.

4. The MAIN type of erosion that happens on sandy soils is: 1-Glaciers. 2-Land slippage. 3-Water. 4-Wind.

5. Of all the types of erosion, which form is the MAJOR cause of soil loss in North America? 1-Glacier erosion 2-Land slippage 3-Water erosion 4-Wind erosion

6. When small channels form on sloping land where running water from precipitation has washed soil away, it is BEST called: 1-Gully erosion. 2-Rill erosion. 3-Sheet erosion. 4-Slippage erosion.

7. Land slippage is best described as soil erosion that occurs: 1-On level, clayey soils. 2-On bottomlands near rivers. 3-On sloping, water saturated soils. 4-On sandy soils near the tree line.

8. The planting of vegetation on excavated soil to hold it in place is a land treatment called: 1-Cover crop. 2-Mulching. 3-Silt fence. 4-Strip cropping.

9. The use of rip-rap, fabrics, straw, vegetation or concrete on a creek or roadside bank to prevent erosion is called: 1-Mulching. 2-Silt fence. 3-Stabilizing. 4-Waste management.

10. Planting on the contour is a soil conservation method described as: 1-Making ridges of earth across a slope. 2-Planting across the slope of a hill. 3-Planting different crops from year to year. 4-Constructing small ditches across slopes.

11. Not planting the same crop in the same place year after year is know as: 1-Conservation tillage. 2-Diversion ditchers. 3-Rotating crops. 4-Strip cropping.

12. Planting different crops in alternate sections on sloping land is called: 1-Conservation tillage. 2-Rotating crops. 3-Strip cropping. 4-Terracing.

13. What is it called when rows of trees are planted to prevent soil erosion on level, sandy land? 1-Conservation tillage 2-Diversion ditch 3-Strip cropping 4-Windbreak
