Four World Heritage Sites custom essay

[pewslideshow slidename=anim2]

Look around your home. Are your floors, sinks, or countertops made of stone? In recent times, humans have used more synthetic building materials, but throughout history stone has been one of the primary building materials used. As you have learned in Chapter 9, the Parthenon, Kilwa Kisiwani, Mesa Verde, and Machu Picchu (World Heritage Sites) have been worn down from their former glory by biological, chemical, and physical weathering. Factors such as rainfall, temperature, rock type, elevation, and vegetation all play a part in the rate of weathering. In this week’s Discussion, you will think about the characteristics of each site, and whether or not some sites are more prone to mass wasting and weathering than others.

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 253 to assist you with your analysis.

?Parthenon, Greece
?Kilwa Kisiwani, Tanzania
?Mesa Verde, U.S.A.
?Machu Picchu, Peru

•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.
With these thoughts in mind:

Post by Day 3 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. Then in a second paragraph, 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.
