Most composite volcanoes have a crater at the summit which contains a central vent or a clustered group of vents. Lava either flow through breaks in the crater wall or from fissures on the flanks of the cone. Lava, solidified within the fissures, form dikes that act as ribs which help to strengthen the cone.
Others are formed when the summit of a volcano collapses into an empty magma cavern that had stored the magma prior to eruption. Shield Volcanoes. Shield volcanoes, formed when large flows of lava spread rapidly from central vents or rows of vents, are the largest volcanoes.Because the lava moves rapidly and spreads out in a broad area, it does not form a tall, steep cone. Instead, shield volcanoes are dome-shaped mountains with broad bases and gentle slopes.tratovolcanoes, or composite volcanoes, get their name from the different layers, or strata, of ash and lava that form them. Most stratovolcanoes are irregularly shaped mountains formed by material ejected from both a central vent and other vents on the sides of the mountain.
