volcano a mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapour, and gas are or have been erupted from the earth's crust.
lava hot molten or semi-fluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this.
vent an opening that allows air, gas, or liquid to pass out of or into a confined space.
