Volcano shapes - shield, composite/stratiform, caldera - and chemistry
from GEO Podcast · host Gary Lewis, GEOetc.com
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! Interested in joining us on a trip?
