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.arrow_forwardNon-Foliated metamorphic rocks are usually found near a. Glaciers b. Intrusive ingenious rock c. Oceans d. Lava Flowsarrow_forward
- 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. Continental crust at sea level averages about 35 kilometers thick. (1 km = 0.6 miles.) Therefore, in general, how thick must the crust…arrow_forwardFoliated metamorphic rocks are created by a.

- 1. How old is a rock if the mineral biotite from the rock has 85,000 40K atoms and 15.000 40Ar atoms? Note: 40K decays to 40Ar with half-life = 1.3 billion years. 2. Isotopic analysis of a granitic intrusion indicates that 6.25 % of the original 40K is present. Analysis of a nearby basaltic intrusion indicates that 25 % of the original amount of 40K is present. What is the absolute age of both the granitic intrusion and the dike? What is the relationship between them? I. 3. Pebbles of an igneous rock are incorporated within a conglomerate. The pebbles yield a radiometric age of 200 million years. What can you say about age of the conglomerate based on this data? 4. A radioactive parent isotope with 600 atoms. After the decay, 450 daughter atoms were produced. Calculate the age of the rock if you know that the half-life of the parent isotope is 20 million years.arrow_forwardHow does sedimentary rock from the ocean floor sometimes end up in highland and mountainous regions on the Earth? (22.5) (a) Sedimentary rock is commonly made inside volcanoes. (b) Wind and water carry the sediment to the mountaintops. (c) It is believed that asteroid impacts probably caused the sedimentary rock to move great distances. (d) The sedimentary rock was uplifted by powerful forces to form mountain chains.arrow_forwardWhich metamorphic change is brought about primarily by heat?
