WebThe higher the temperature of magma is, the lower is its viscosity. As lava flows, it cools and begins to harden, its ability to flow decreases and eventually it stops. Next, let’s look at how the composition of magma affects its viscosity. Magmas with high silica content are more viscous than those with low silica content as shown in Figure 6. http://sci.sdsu.edu/how_volcanoes_work/Controls.html candlepin bowling davis squareWebNow you’re going to add more “silica” to see how this changes the viscosity of your magma.
