Lava is molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon. Ash cloud is occur where a violent explosive eruption ejects volcanic ash into the atmosphere. Magma is the molten or semi-molten natural material from which all igneous rocks are formed. Volcano is a rupture in the crust of a planetary-mass object, such as Earth
