Volcano shapes - shield, composite/stratiform, caldera - and chemistry

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!
