Constructing a Topographic Map 7.7 Construct a simple topographic map by drawing contour lines. Early topographic maps were constructed by first surveying an area and establishing the elevations at numerous locations. The surveyor then sketched contour lines on the map by estimating their position between the points of known elevation Today, topographic maps are made by computers from radar data or a series of stereoscopic aerial photographs similar to those in Figure 7.2. The data from these images is processed...

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...
