Composite Volcano Diagram
Composite Volcano Diagram. Stratovolcanoes form on the continental side of a subduction zone where the melting oceanic crust forms pools of molten rock in a magma chamber. A composite volcano is also commonly called a stratovolcano.
These volcanoes are built from layers, or strata, of pyroclastic material, including lava, pumice, volcanic ash, and tephra.
Stratovolcano is another name for composite volcanoes.
Composite volcanoes are made up of alternating layers of lava and ash (other volcanoes just consist of lava). Name the type of volcano illustrated in diagram b. describe how its formed. The low viscosity, runny, nature of the lava means it travels in streams far from the source and covers many square miles.
