Volcano
Description
A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, ash and gases to escape from below the surface. The word volcano is derived from the name of Vulcano island off Sicily which in turn, was named after Vulcan, the Roman god of fire. Volcanoes are classified based on its volcanic activity as active, potentially active and inactive. Hotspot volcanoes are also found elsewhere in the solar system, especially on rocky planets and moons.
