Question

Could someone please help me with this question? Fractures (5 points) a. 2. Fractures affect the permeability of rock. Using the Cubic Law, calculate the effective vertical permeability of fractured shale containing one vertical fracture per linear meter, with an average fracture aperture of 0.2 mm. Give your answer in both m and in Darcy. b. Does this fractured shale have a higher or lower permeability than the sandstone in Problem 1? Would this serve as an effective cap rock? Explain. 3. Sea level rise (15 points) The two principal drivers of sea level rise are thermal expansion and melting ice. Estimate what percent of the global average sea-level rise that has occurred since 1900 comes from each of those factors and what the projections from each factor are through 2100. Read this article (https://agupubs onlinelibrary wiley.com/doi/10.1029/2011GL048604) and explain how and why groundwater depletion is causing sea-level rise How much sea-level rise happened since year 1880? List five consequences that a. b. C. sea level rise will have for our society?

Explanation / Answer

3. sea level rise:

In the context of oceans, thermal expansion is the increase in volume of ocean water as a result of increased temperature of the water. • A rise in global sea level due to the warming caused by only two effects:

It is estimated that most of the increase in sea level will be from as the result of global warming, which will cause thermal expansion of the oceans.
