how do composite volcanoes form
Which causes it to burn making the magma turn into lava. Once the lava hardens it then forms a Composite Volcano. its fromed by putting your hand in the volcani and than seeing if the magma comes up and goes thrugh the vent. the volcano is a vent on the earth surface A composite volcano is formed from eruptions of often viscous molten rock. Some eruptions are explosive, producing ash, pumice, and cinders. Other eruptions are effusive, producing lava domes and lava flows. This material gradually piles up in layers, forming a composite volcano.
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.
