15. How do basalt and granite differ from gabbro, andesite, rhyolite, and diorite? 16. What is aspect in the context of topography? 17. What are the five hill slope components? How does water and sediment movement vary among the five components? What is a catena? 18. Forest and prairie vegetation have profound effects on the cycling of organic matter and its distribution in the soil. Discuss these effects in the context of root:shoot ratio for the two vegetation types. 19. On average, soils of high latitudes store more organic carbon than do soils in the tropics. Explain why this is the case, taking into consideration biomass production in the two environments. 20. How does climate influence soil processes? How are precipitation, temperature, and evapotranspiration relationships depicted in a water budget graph? 21. What is meant by the statement: “Soils are clay factories.”? 22. As soils weather in a well-drained, humid environment, what major properties are expected to change on progressively older landscapes? 23. In an arid environment, how would soil properties compare with those discussed in the question above?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
