A volcano is a vent or chimney which transfers molten rock known as magma from depth to the Earth's surface.Magma erupting from a volcano is called lava and is the material which builds up the cone surrounding the vent. A volcano is active if it is erupting lava, releasing gas or generates seismic activity.agma erupting from a volcano is called lava and is the material which builds up the cone surrounding the vent.
