Composite Volcano. Introduction. A composite volcano is also known as a stratovolcano. These volcanoes form tall, conical shaped mountains. Most of the Earth's active volcanoes have formed a ring around the Pacific Ocean. There are 452 stratovolcanoes in the Pacific Ring of Fire.he lava is less fluid and forms thick lava flows on the sides of the volcano. Sometimes the lavas form small dome volcanoes over the vent in the crater of a stratovolcano or on its steep sides. Eruptions of statovolcanoes. Stratovolcanoes erupt less frequently than shield volcanoes which have formed over hot spots.
