a) You are the captain of the Titanic and spot an iceberg that stands 10 meters above the sea surface (the black solid line in the figure). How thick is the iceberg? The Titanic was about 43 meters from waterline to the top of its smokestacks –how does this compare to the total thickness of the iceberg? b) Calculate the difference in average elevation between continental crust (granite, 40 km thick) and oceanic crust (basalt, 7 km thick)? In this case, the asthenosphere is the compensation layer. How does this compare to the average depth of the ocean basins (the abyssal plain)? (note: the black solid line is not sea level –which depends on the amount of water in the Ocean). c) Mount Everest (Sagarm\bar (a) th\bar (a) to the Nepali) is about 8000 meters above the average continental crust elevation. How much thicker must the crust be to support this height isostatically? d) Why is the crust this thick (think plate tectonics)? e) (trick question) If 1,000 meters (1 km) of rock is weathered off the top of Everest and washed downhill into the Ocean, how tall is Everest (given your answer from c)) above the average continental crust elevation now?
