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.
1.
A giant ice sheet expands quickly over the surface of North America. For how long
must the ice sheet remain in place in order to cool the crust to a depth of 2000 m? The thermal
diffusivity of crustal rocks is ~ 10-6 m²/s. Give your answer in years.

- 5. 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.

To illustrate the tremendous pressure that exists deep underground where granite bodies are emplaced, answer the following question. Stone Mountain granite in Georgia has an area of 4.1 square kilometers and was emplaced 16 km deep. If we assume that Stone Mountain granite is present in an area that has more or less a rectangular shape with dimensions of 1 km by 4.1 km and that it was buried under 16 km of metamorphic rock material with a density of 2.6 g/cm³. We can calculate the weight of metamorphic rock over the Stone Mountain granite when it was emplaced and before erosion removed that material. First, we need the volume of the metamorphic rock that existed over Stone Mountain. The volume of a rectangular prism that represents the metamorphic rock over Stone Mountain is length x width x height. In our case: 1 km x 4.1 km x 16 km= 65.6 km³ Now we can use the relationship: Density x Volume= Mass However, we need to change our density units from 2.6 g/cm3 to kg/km3, and then we…arrow_forwardSupercooled water freezing onto a snowflake is called a. a.
