8.3.3 Composite Volcano

A composite volcano or stratovolcano is a conically-shaped mountain which slopes about 30 degrees at the summit, and tapers off to 5 degrees near the base. A composite volcano is made up of alternating layers of ejected pyroclastic material and lava flows. Composite volcano eruptions are usually explosive, and exude a high viscosity lava.
