You should allocate your time accordingly. Lithospheric Processes, Hazards and Management 1. Figure 1 shows a rock that has been weathered along its joints. (a) Identify and describe the outcome of weathering that is evident in Figure 1. [2] (b) With reference to a specific weat hering process, show how it has led to the outcome above. [5] (c) Explain how a different weatheri ng process from the one in (b) can result in another type of weathering outcome. [5] Hydrologic Processes, Hazards and Management 2. Figure 2 is from a newspaper article on the Three Gorges Dam in China. (a) With the aid of Figure 2, s how how catchment management through dam construction can create conflicts of interest. [6] (b) Suggest how the negative impacts highlighted in Figure 2 may be ameliorated for the affected groups. [6] Atmospheric Processes, Hazards and Management 3. Figures 3A and 3B show the track of major hurricanes occurring in the U.S. for the periods 1971-1980 and 1991-2000.
