B. core
C. mantle
D. asthenosphere
13. How deep in the crust is 10 kbar? Lithostatic pressure within the crusts results from the
weight of the rocks above. Assume an average density of 2750 kg/m3. Use the equation
P=p*g*h or P/(p *g)=h 23kPa/m
P=pressure (e.g. kbar), p=density, g-gravity 9.8 m/s2, h= depth (m), 1 kbar=1,000 bars, 1
bar=100,000 Pa, 1 Pa=kg/(m*s2), 1 kbar =100,000,000 Pa, 1 km =1000 m. Give your answer in
kilometers.

A. liquid inner core B. liquid outer core C. solid inner core D. solid outer corearrow_forward5. The "iceberg analogy" for the isostatic equilibrium of the continental crust turns out to be quite the relative density of icebergs versus seawater is close to the relative density of continental crust versus mantle. Glacial ice is about 15% less dense than seawater; likewise continental crust is about 15% less dense than the mantle. This leads to a simple rule that we can call the 1-to-8 rule: for every 1 unit of extra elevation for an iceberg or a mountain belt, there need to be 8 units of total thickness. These iceberg examples illustrate the idea: an iceberg 3 meters above sea level is 24 meters thick an iceberg 1 meter above sea level is 8 meters thick an iceberg 2 meters above sea level is 16 meters thick 3m 2m water level 1m >7m 14m 21m For the following questions, apply the 1-to-8 rule, assuming continental crust in isostatic equilibrium. a.
