Question

Advanced 20. Archimedes's principle is a useful tool to model the depth to which continents sink into the mantle rock. Consider a continental crust of average density pcc shown in Figure 1-17. The continental crust sinks a distance d into the mantle rock, with density at its top strata of p Surrounding the continent are oceans of average density po-1030 kg/m3 and depth ho Beneath the ocean is the oceanic crust of thickness hoe which has a density sufficiently different from the mantle that it should be considered separately from the mantle. Using the data in the figure, calculate the depth d that the continent sinks into the mantle. Ocean Oceanic Crust ho6.6km, -1,030 kg/m lhoc-6.0km, ???-2.900 kg/m2 Continent Pec-2.800 kg/m2 Mantle Pm -3,300 kg/ma
