B. core
C. crust
D. asthenosphere
11. Which part of the Earth is a hot, elastic semi-liquid layer that extends around the entire Earth?A. crust
B. core
C. mantle

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.

The energy released đuring an earthquake can be calculated using the formula E(M) =(10'")“, where E is the energy in kWh (kilowatt hours) and M is the magnitude of the carthquake. a. The magnitude 9.5 earthquake in Southern Chile on May 22, 1960 is thought to be the strongest earthquake that has ever occurred. Use the formula above to caleulate the energy released during this earthquake. Express the answer in scientific notation, to the nearest tenth. b. An earthquake of magnitude 3 may not be felt or noticed by most people. Calculate the energy, to the nearest tenth, that is released during an earthquake of this strength. ( c. Compared to a magnitude 3 carthquake, how many times greater was the energy that was released during the 1960 earthquake in Chile? d. An earthquake that occurred in Central Canada in 2010 released approximately 30 000 000 kWh energy. Find the magnitude, to the nearest whole number, associated with this carthquake.arrow_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.
