Volcanoes A volcano is an opening in the Earth's crust. It allows hot magma, ash and gases to escape from below the surface. Magma chamber - large underground pool of magma.
Lava - magma, once it reaches the surface. Crater - bowl-shaped basin in the top of the volcano. Vent - central tube which magma travels through.
Secondary cones - eruptions from other vents may build up secondary cones on the flanks. Ash, steam and gas - material thrown out by the volcano. Volcanic bombs - larger material thrown out by the force of eruption.
