Ask.com Answer for: how are volcanoes formed
Volcanoes are created from a opening in the Earth's crust, which allows hot magma, ash and gases to escape. They form in the shape of cones, domes or simple fissures.
Volcanoes generally form where tectonic plates are diverging or converging. They can also form where there is stretching and thinning of the Earth's crust (called 'non-hotspot intraplate volcanism'). For additional information check the links below.
Volcanoes are formed when the magma from the inside of the earth explodes into the earth's surface. The magma comes from the Earth's upper mantle. You can find more information here: http://www.infc.ulst.ac.uk/computing/stepup/volcanoes/how_are_volcanoes_formed.htm
