This online simulator lets students observe what happens to volcanic eruptions as the silica content of the magma changes. Operating a slider changes the percentage of silica, and the display shows the rock type, type of eruption, and type of volcanic edifice. It also displays temperature, pressure, viscosity of the lava, and seismic activity. A brief tutorial describes how to use the simulator and explains how the nature of eruptions and the type of rock produced changes with silica content.
