Magma composition is an important control on the geomorphology of lava flows and volcanoes. In this exercise, students investigate this relationship by studying several classic examples of diverse volcano types in the western United States. Students use the interactive Google Earth software to determine the size and shape of the selected volcanoes, and then use the North American Volcanic and Intrusive Database (NAVDAT) to gather whole-rock geochemical data to test the nature of the relationship between magma composition and volcano geomorphology.
