- When 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.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 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.)

- 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.On August 17, 1983, an earthquake with a magnitude of 5.3 in the Richter scale hit the province of llocos Norte. This was the most sever earthquake in North-western Luzon in 52 years and probably the second largest earthquake to hit Laoag City and its immediate vicinity in historical times (Source: philvocs.dost.gov.ph).
