Question 1 0.5 / 0.5 pts In Google Earth go to (-86.920494°, 61.056563°) and then change the eye altitude to about 4700 miles above the surface. What is the order of relief and the major process(... es) generating that relief? Also, what is the total relief from the highest peak to the elevation of the continental shelf at this location (-74.494594°, -49.023300°)? This is a 1​st​ order feature. It is produced by plate tectonic processes. The relief from highest peak (​Mount VinsonLinks to an external site. ​) to sea level is 16,066 feet. Correct! This is a 1​st​ order feature. It is produced by plate tectonic processes. The relief from highest peak to the shelf just off Antarctica is about 17,500 feet. This is a 1​st​ order feature. It is produced by glacial processes. The relief from highest peak (​Mount VinsonLinks to an external site. ​) to sea level is 16,066 feet.This is a 3rd order feature. It is produced by glacial processes. The relief from highest peak (​Mount VinsonLinks to an external site. ​) to the shelf just off Antarctica is about 17,500 feet. The continent of Antarctica is a 1​st​ order relief feature produced by plate tectonic processes. The highest point in Antarctica (​Mount Vinson​Links to an external site.​) is about 16,066 feet. Then, the continental shelf at the indicated location is about 1400 below sea level. Thus, the total relief between the highest point on the continent and the adjacent shelf is about 17,500 feet (rounded off). Question 2 0.5 / 0.5 pts Grand Canyon is Arizona’s iconic physical geography feature, no matter whether you look at it from the​ ​bottom (Links to an external site.)​ ​or from​ ​the top (Links to an external site.)​. ​In Google Earth go to (36.100817°, -112.089503°) and change the eye altitude to about 30 miles above the surface. What is the order of relief that you are seeing and what would be the major process(es) generating the observed relief. Also, what is the total relief from the high point of the North Rim (36.197536°, -112.052940°) to the Colorado River (36.100817°, -112.089503°) near Phantom Ranch? 2nd order of relief (about 5800 feet) generated by deposition of sedimentary rocks. 3​rd​ order of relief (about 5800 ft) generated by faulting dropping down the Grand Canyon. Correct! 3​rd​ order of relief (about 5800 ft) has been generated by weathering, mass wasting, fluvial processes.2​nd​ order of relief (exactly 8218 ft) generated by uplift of the Kaibab Plateau during the plate tectonic Laramide Revolution between 40 and 70 million years ago. The Grand Canyon as viewed from the bottom or the top is a 3​rd​ order of relief landform. The Grand Canyon formed by a mix of three general types of processes: rock decay (weathering) breaking apart the sedimentary rocks; then mass wasting (rock fall, rock avalanches, debris flows) carried rocks down to ephemeral river channels. Then, during flooding, these channels transported rocks down to the Colorado River. All of these processes widened the canyon. Erosion by the Colorado River itself both deepened the canyon and also keeps the canyon clear of rocks by transporting the all of the rock material entering the canyon downstream. Colorado River near Phantom Ranch (36.100817°, -112.089503°) has an elevation of about 2425 feet. The North Rim Dining Hall (36.197536°, -112.052940°) has an elevation of about 8218 feet, resulting in a relief of about 5800 feet or more than a mile. Question 3 0.5 / 0.5 pts In Google Earth go to Mount Everest (27.987332°, 86.895156°) and change the eye altitude to about 13 miles above the surface. What is the order of relief that you are seeing and what would be the major process(es) generating the observed relief. Also, what is the total relief from the high point of Mt Everest (27.987850°, 86.925026°) and the Base Camp at (28.0013008,86.8510439). [Show More]
