Volcanoes can be of different shapes and sizes, but all contain some basic parts. The essential parts of a typical volcano are: 1) magma chamber, 2) lava, 3) primary vent, 4) throat, 5) conduit, 6) crater, 7) summit, 8) secondary vent, 9) secondary cone, 10) lava flow, and 11) ash cloud.

Ash, Steam, and Gas - cloud which is pushed out of the volcano Secondary Cone - a cone that builds up around secondary vents Secondary Vent - place where magma reaches the surface without going through the main vent Crater - circular depression at the top of the volcano Magma Chamber - store of underground magma
