Composite volcanoes, sometimes called stratovolcanoes, are typically deep-sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8,000 ft above their bases.
Most composite volcanoes have a crater at the summit that contains a central vent or a clustered group of vents. Lavas either flow through breaks in the crater wall or issue from fissures on the flanks of the cone.
TypesofCompositeVolcano
Stratovolcanoes are also called composite volcanoes because they are built of layers of alternating lava flow, ash and blocks of unmelted stone, according to the U.S. Geological Survey.
Cinder cone volcanoes (also called scoria cones) are the most common type of volcano, according to San Diego State University, and are the symmetrical cone-shaped volcanoes we typically think of.
Shield volcanoes are huge, gently sloping volcanoes built of very thin lava spreading out in all directions from a central vent.
A volcano with a broad base, steep sides, and often a crater at the top. The volcano is composed of alternating layers of ash and lava flows. Also called a stratovolcano.
