Volcanoes are geological formations on the surface of the crust of the Earth or another planet, where magma comes to the surface, forming lava, volcanic gases, stones (volcanic bombs and pyroclastic flows). The word "volcano" comes from the name of the ancient Roman god of fire Vulcan.The so-called mud volcanoes are not actually volcanoes and are related to post-volcanic phenomena.
