EXERCISE 15.4Landforms at the Terminus of a Continental Glacier (continued)Name:Course:Section:Date:FIGURE 15.8a is a map of the Arnott moraine in Wisconsin, formed approximately 14,000 years ago. It shows the classicirregular knob-and-kettle topography of terminal and ground moraines. Compare this morainal area with the fluvial landscapeshown in FIGURE 15.8b.(c) Are the stream networks and divides as well developed and clearly defined in the morainal area?(d) Suggest an explanation for the absence of a well-integrated drainage system in the morainal area.(e) Suggest an explanation for the numerous swampy areas in the morainal landscape.(f) Compare the sizes and shapes of the hills (knobs) in the morainal landscape with those in the fluvial landscape.(g) Suggest an origin for the several small lakes in the morainal area. What will be their eventual fate?(h) There are several gravel pits in the morainal area. Why might gravel be more easily and profitably mined from thesespecific areas than from others?(i) What difficulties do you think might be involved in farming on a ground moraine?15.3 LANDSCAPES PRODUCED BY CONTINENTAL GLACIATION393
