Is Mayon Volcano an acidic or a composite volcano?
Mt Mayon in Philippines is a composite volcano because: Composite volcanoes consists of alternate layers of viscous lava, ash and cinder. It is generally steep towards the top and gentler at the base. The viscous lava solidifies in the central pipe, blocking the passageway. This prevents rising magma and trapped gases from escaping, building up pressure beneath. There will be and explosive eruption of ash and cinders at first, which will drop back around the vent. Lava then excapes and flows over the ash and cinders. Viscous lava solidies in the pipe once again, and this process is repeated again. Violent eruptions of ash and cinders followed by lava forms a composite volcano.
