QUESTION 5 Suppose there is a river transporting gravels, sands, and muds (that's pretty common). Now suppose flow velocity starts to slow down (but just a little bit). Which of the following would you expect would occur. O the rate of erosion would increase O muds that had been in transport would start to be deposited O gravels and large sands that had been in transport would start to be deposited all the above QUESTION 6 Where would you expect the highest rates of soil erosion to occur? O flat, forested regions O farmland O city centers where there is a lot of concrete and asphalt O mountainous regions with little human activity QUESTION 7 Which of the following is true about how humans have influenced soil profiles? O we've increased the rate of soil production (i.e., the 'flow in') O we've increased the rate of soil erosion (i.e., the flow out') O we've made the mass balance of soil profiles more positive O we've increased the residence time of soil profiles QUESTION 8 Which of the following is always true about a reservoir with a positive mass balance? O there will be a greater number of different flows coming into the reservoir than going out of it O the reservoir will be in equilibrium O the amount of mass flowing into the reservoir will be larger than the amount of mass flowing out of the reservoir O the residence time of the reservoir will decrease over time
