Study Notes
- Physical weathering increases the surface area of rocks, thereby increasing chemical weathering.
- Chemical weathering increases physical weathering.
- Decreasing slope angle and plowing across the slope best reduces soil loss from a sloped field.
- Cumberburg and Dumble will undergo the most weathering in a 50-year period.
- The correct order for a soil horizon from the surface down is O, A, E, B, C.
- Eluviation occurs in the E horizon.
- Soil erosion by wind occurs most in the Great Plains.
- Regolith is not essentially the same as soil.
- Soils are a non-renewable resource.
- Biological weathering is essential for soil formation.
- Biological weathering occurs at both the macro- and micro-levels.
- Quartz is not easily weathered compared to other minerals.
- Porosity does not describe how rapidly water moves through a rock.
