Document Summary

Shape: flat, wide, low slopes, plateau, emitted from fractures. Shape: small tephra cone mountains, angle at top where lava flows, internal layers of lava. Eruption: big explosive, small emitted from vent, may build up a shield. Magma type: basaltic. high viscosity, high volume, small volatiles viscosity, med/high volume, large volatiles volume, very large volatiles. Shape: circular depression in earth, water reenters and forms a dome gathers in hole, forms cones inside hole have a crater. Eruption: explosive, have craters emitted from central vent.
