A volcano is an opening or rupture in the earth's surface that allows magma (hot liquid and semi-liquid rock), volcanic ash and gases to escape. They tend to be pitted and full of holes, which gives them a low density.Along with water vapor and other hot gases, volcanic ash is part of the dark ash column that rises above a volcano when it erupts. The chemical composition, volume of trapped gases, and temperature of the magma all determine the kind of volcano that will form and the type of eruption, if any.
