Q2. 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…

With the information from Exercise 8.25, you can calculate the average age of the ocean floor. First, find the total area of the ocean floor (equal to about 60% of the surface area of Earth). Then compare this with the area created (or destroyed) each year. The average lifetime is the ratio of these numbers: the total area of ocean crust compared to the amount created (or destroyed) each year.

Antarctica is roughly semicircular, with a radius of 2000 km . The average thickness of its ice cover is 3000 m. How many cubic centimeters of ice does Antarctica contain? (Ignore the curvature of Earth.)

A11 Consider linear flow through a core length L with cross sectional area equal to A. Assume that flow through the core can be modeled as flow through ncapillary tubes of radius r and length L. Show that; k = 4.04 x 10^6 x Φ x r^2 where Φ denotes porosity, and k denotes permeability in Darcies.

A seismic survey is conducted in a region with two layers. The top layer is shale, with density 2500 kg/m3, and seismic velocity of 2900m/s, and the bottom layer is sandstone, with a density of 2100 kg/m3, and a seismic velocity of 3000m/s. The reflection coefficient will bea. Positiveb. Negativec. Zerod. Not enough information

Earth's surface area is 5.10x10^8 km^2 .Earth's crust has a thickness (or depth) of 35 km and density 2.8 g/cm^3 for earth's crust. d) Silicon's concentration in earth's crust is 2.72x105grams/ton. Calculate the mass of silicon (in grams) present in earth's crust.

21. Your town has built a new water tower and has decided to cover the sides with wallpaper. You've been tasked with calculating how many square feet of wallpaper are necessary. The water tower is 25 meters tall with a diameter of 10 meters. (Hint: you're looking for the lateral side area; and be careful of your units!) 2ad sloo A L

A golden-colored cube is handed to you. The person wants you to buy it for $100, saying that is a gold nugget. You pull out your old geology text and look up gold in the mineral table, and read that its density is 19.3 g/cm3. You measure the cube and find that it is 2 cm on each side, and weighs 40 g. What is its density? Is it gold? Should you buy it? Draw also a figure or free body diagram that support the problem, and the discovery after solving it.

The Ocean's level is rising about 1.5 millimeters (mm) per year. At this rate, in how many years will the sea level be 3 m higher than it is now? You must include a SKETCH to solve.
