stratovolcano (or composite volcano) — a conical volcano consisting of layers of solid lava flows mixed with layers of other rock.
cinder cone volcano — doesn’t have any horizontal layers, and is instead a steep conical hill of tephra (volcanic debris) that accumulates around and downwind from the vent.
shield volcano — a type of volcano built entirely or mostly from fluid lava vents. They are named like this because when viewed from above, you can see just how massive and imposing they are – like a warrior’s shield.
