To prepare for this Discussion:
Analyze the following four World Heritage Sites listed in figure 9.1 in Chapter 9 of the course text for physical, chemical, and biological weathering. Use Table 9.1 on page 240 to assist you with your analysis.
Parthenon, Greece
Kilwa Kisiwani, Tanzania
Mesa Verde, U.S.A.
Machu Picchu, Per
Determine which site is at the greatest risk of weathering. Rank the locations 1 through 4 on their potential for weathering (with 1 being the highest risk).
Determine which one site is at greatest risk from mass wasting.
Post a paragraph with your ranking of the four locations, from the highest risk (1) to the lowest risk (4) from weathering, and explain why you have ranked them this way. Address the type of rock relevant to each location and the type(s) of weathering that impact this site. Then, in a second paragraph, explain the term mass wasting. State which site is most at risk for mass wasting and explain your rationale. If you believe none of the four sites are at risk, explain why.
Be sure to support your ideas by connecting them to the week’s Learning Resources, or something you have read, heard, seen, or experienced.
