... I. What is a volcano? A volcano is basically a vent (hole in the ground) through which magma can rise to the earth’s surface. Lava flowing from fissures (long cracks in the ground) are more common than volcanoes. Magma is molten rock. Magma, which reaches the surface and flows, is called lava. Lava ...
