- Identify the parent material/s for each local soil. Use the appropriate name (e.g. residuum, colluvium, etc. and the rock type if the parent material is residuum; e.g. residuum – shale).

- Define argillic horizon.
- Define Aridisol.
- Define mollic epipedon.
- Define cambic horizon.
- Compare the rate of nitrate fertilizer leaching in an arid climate versus a humid climate.
- Compare the rate of soil profile development in the Brazilian rainforest versus on the prairie east of Laramie.
- How would soil temperature, evaporation, and soil formation differ for soils forming on north versus south facing slopes (assume the same parent materials and landscape positions)?
- North aspect:
- South aspect:
- What differences can be expected in two soils formed from the same parent material, but where one soil occurs on a 1 % slope (summit) and the other soil occurs on a 35 % (backslope) slope with all other soil-forming factors being the same?
- 1 % slope:
- 35 % slope:
- How does soil color change with depth for the soil profile? Explain.
- How does soil texture change with depth for the soil profile? Explain.
