In this episode, I talk about how volcanoes get different shapes due to the chemistry of the molten rock materials.  We talk about the shield, composite/stratiform and caldera volcanoes…and a little about cinder cones.   We mention silicate chemistry and the effect of water on shapes and eruption style.

This is a great primer to volcanoes!
