- Calculate how much of a glacier is below the exterior of the ocean, given that the density of ice is 917 kg/m^3 and salt water has density 1025 kg/m^3.33 Calculate how much of a glacier is below the exterior of the ocean, given that the density of ice is 917 kg/m^3 and salt water has density 1025 kg/m^3. (Report answer in 3 SF; unit: %) *Rocks are sometimes used along coasts to prevent erosion. If a rock needs to weigh 2,000 kilograms (about 2 tons) in order not to be shifted by waves, how big (what volume in inches) does it need to be? You are using basalt, which has a typical density of 3200 kg/m3.
- Rocks are sometimes used along coasts to prevent erosion. If a rock needs to weigh 2,000 kilograms (about 2 tons) in order not to be shifted by waves, how big (what volume) does it need to be? You are using basalt, which has a typical density of 3200 kg/m3When it comes to protecting coastlines from erosion, rocks are sometimes used as a barrier. In order for a rock to not be shifted by waves, it must weigh 1,000 kilograms (approximately 1 ton). How big (what volume) does the rock need to be? You are using basalt, which has a typical density of 3200 kg/m3.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…
- Today, the lowest part of Death Valley is near Badwater, an elevation of 85 meters below sea level. One of the abandoned shorelines, cut by waves when the basin was filled with water as a lake during the Pleistocene, is found at an elevation of 80 meters above sea level. Estimate the depth of this lake stand during the Pleistocene.The distortion of the earth's crust is an example of sheer on a large scale. A particular rock has a sheer modulus of \(1.2 x108 Pa (N/m² ) \)(Shear Modulus, S). what shear distance (Ax) can a 473011N/m2 of shear stress can create when it is applied to a 3km layer (h) of rock ) ? (Include the Sl unit in your answer.)d) Describe how porosity and permeability are associated with one another.
- The average elevation of Arabian peninsula (freeboard) is f=400 m. Considering that the oceanic crust is h=5 km of thickness and the sea average depth is D= 3700 m. (pc=2700 kg/m3, po=3000 kg/m3, pm=3300 kg/m3 pw=1000 kg/m3) What is the thickness H of the continental crust. B. If the Musandam has an average elevation of 800 m. How much is the thickness below Musandam considering stacking of sedimentary layers and not erosion.A non-artesian well is drilled in an aquifer with a fairly horizontal water table. The well (φ = 25 cm) has a discharge of 408 m3 /hr, creating a 250 m wide cone of depression. If the height/depth of the water table is 60 m and the aquifer permeability is 8 m/day, determine the drawdown. Include also diagram or drawing.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.
