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. [1] |

A volcano is a geological landform (usually a mountain ) where a substance, usually magma (rock of the Earth's interior made molten or liquid by extremely high temperatures along with a reduction in pressure and/or the introduction of water or other volatiles) erupts through the surface of a planet . Although there are numerous volcanoes (some very active) on the solar system 's rocky planets and moons, on Earth at least, this phenomenon tends to occur near the boundaries of the continental plates . However, important exceptions exist in hotspot volcanoes . |

A volcano (plural, volcanoes) is a geological landform (usually a mountain ) where magma (rock of the earth's interior made molten or liquid by high pressure and temperature) erupts through the surface of the planet . Although there are numerous volcanoes (some very active) on the solar system 's rocky planets and moons, on Earth at least, this phenomenon tends to occur near the boundaries of the continental plates . However, important exceptions exist in so-called hotspot volcanoes . |

A volcano is a geological landform formed where magma comes close to the surface of a planet . On earth , this phenomenon tends to occur near the boundaries of the continental plates (see, however, hotspot volcanoes ). The process begins when magma rises to near the surface deep beneath a volcano, occupying a magma chamber. Magma in the chamber is forced upwards and flows from a vent as lava , or can react with water in the surrounding landform and cause explosive discharges of steam, escaping gases from the magma, and ejection of rocks, cinders , volcanic glass , and volcanic ash . |

A volcano is a geologic structure formed where magma comes close to the surface of a planet . This tends to occur at the boundaries of the continental plates . This magma can break the surface and flow as lava (rare), cause rocks above it to melt and flow as lava, or its presence can cause the ejection of cinders , volcanic glass , steam , ash and gases of various temperatures. |

A volcano is a place where the earth's crust is weak, and seismic activity leads to expulsions of lava , gases and brimstone during eruptions . Volcanoes are usually situated either at the boundaries between tectonic plates or over hot spots . Volcanoes may be either dormant (having no activity) or active (near constant expulsion and occasional eruptions), and change state unpredictably. |
