Why does this kind of volcano have the gentlest slope?
In this problem, you will compute the gradients of Mauna Loa in Hawai‘i, Mount Vsevidof in Alaska, and SP Mountain in Arizona. (You may also determine the elevation changes and distances needed to calculate these gradients by using Google Earth™.) The recommended starting point and distance to measure are given for all three volcanoes. What will be an ideal response?
