This material changes the thickness of lava.
What is silica?

This volcano is the same as the composite volcano but has a different name.
What is a stratovolcano?

This is a crack that lava flows out which is not the main vent.
What is the side vent?
500
This is cooler and slower moving lava.
What is aa?
500
These are smaller bodies of magma that form a feature by forcing layers of rock to bend upward.
