This page provides all possible meanings and translations of the word Volcano
Random House Webster's College Dictionary
vol•ca•novɒlˈkeɪ noʊ(n.)(pl.)-noes, -nos.
a vent in the earth's crust through which lava, steam, ashes, etc., are expelled, either continuously or at irregular intervals.
a mountain or hill, usu. having a cuplike crater at the summit, formed around such a vent from the ash and lava expelled through it.
Origin of volcano:
1605–15; < It < L Volcānus, var. of VulcānusVulcan
a fissure in the earth's crust (or in the surface of some other planet) through which molten lava and gases erupt
a mountain formed by volcanic material
Kernerman English Learner's Dictionary
a mountain with a hole at the top through which lava can explode
fears that the volcano could erupt any day; a volcanic eruption
A vent or fissure on the surface of a planet (usually in a mountainous form) with a magma chamber attached to the mantle of a planet or moon, periodically erupting forth lava and volcanic gases onto the surface.
Origin: From vulcano, from Vulcanus the Roman god of fire and metalworking. Perhaps related to Greek πῦρ and καίειν
a mountain or hill, usually more or less conical in form, from which lava, cinders, steam, sulphur gases, and the like, are ejected; -- often popularly called a burning mountain
A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, volcanic ash and gases to escape from the magma chamber below the surface. Volcanoes are generally found where tectonic plates are diverging or converging. A mid-oceanic ridge, for example the Mid-Atlantic Ridge, has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates coming together. By contrast, volcanoes are usually not created where two tectonic plates slide past one another. Volcanoes can also form where there is stretching and thinning of the Earth's crust in the interiors of plates, e.g., in the East African Rift, the Wells Gray-Clearwater volcanic field and the Rio Grande Rift in North America. This type of volcanism falls under the umbrella of "Plate hypothesis" volcanism. Volcanism away from plate boundaries has also been explained as mantle plumes. These so-called "hotspots", for example Hawaii, are postulated to arise from upwelling diapirs with magma from the core–mantle boundary, 3,000 km deep in the Earth. Erupting volcanoes can pose many hazards, not only in the immediate vicinity of the eruption. Volcanic ash can be a threat to aircraft, in particular those with jet engines where ash particles can be melted by the high operating temperature; the melted particles then adhere to the turbine blades and alter their shape, disrupting the operation of the turbine. Large eruptions can affect temperature as ash and droplets of sulfuric acid obscure the sun and cool the Earth's lower atmosphere or troposphere; however, they also absorb heat radiated up from the Earth, thereby warming the stratosphere. Historically, so-called volcanic winters have caused catastrophic famines.
