Theorize the difference in soil development in adjoining soils developed on forested, sloped area versus a grassed flat area. What are the soil-forming factors? Explain the importance of the nature of the parent material to soil formation and type. Then, cite at least 2 examples in which the influence of parent materials might be outweighed by other soil-forming factors. Explain the “struggle” between the internal and external processes in shaping the Earth’s surface. What are the different ways that the surface of the Earth is changed over time?
