7. An elevation difference measurement by a total station is (a) is from the ground point at the total station to the ground point at the prism computed from only slope distance and zenith angle (b) requires the horizontal circle to compute the elevation difference (c) requires sighting a known elevation on a backsight (d) usually requires height of instrument and height of target to be correctly derived 8. A horizontal angle at 2 from 1 to 3 is 65-08-10,...

Exercise : Volcano Shape The purpose of this exercise is to compare the slope of two volcanoes, Hawaii and Mt. St. Helens Hawai: The Hawaiian volcanoes are shield volcanoes, though some cinder cones are present as well. The very low viscosity of mafic/basaltic magma that cools to form the Hawaiian shield volcanoes produces very gentle or shallow slopes. This is a primary characteristic of shield volcanoes. So, let's try to get an impression of just how low the slopes of...
