تعريف volcanism في الإنجليزية الإنجليزية القاموس.: Any of the natural phenomena and processes associated with the action of volcanos, geysers and fumaroles; or vulcanism Any of various processes and phenomena associated with the surface discharge of molten rock or hot water and steam, including volcanoes, geysers, and fumaroles. Most active volcanoes occur where two plates converge and one overrides the other (see plate tectonics). Volcanism can also occur along the axis of an oceanic ridge, where the plates move apart and magma wells up from the mantle. A few volcanoes occur within plates, far from margins. Some of these are thought to occur as a plate moves over a "hot spot" from which magma can penetrate to the surface; others appear to result from an extremely slow form of plate spreading; The eruption of molten material or gas-driven solid fragments onto the surface of a planetary body On icy moons the phenomenon is sometimes called cryovolcanism to distinguish it from silicate or sulfur volcanism; the phenomena associated with volcanic activity; Volcanic power or action; volcanicity; {i} volcanic processes and phenomena; Any of the phenomena and processes associated with the action of volcanos, geysers and fumaroles; The phenomena of volcanic activity Large volcanic eruptions spew massive amounts of ash into the atmosphere that absorb solar radiation, thus potentially generating a cooling effect on planetary temperatures At the same time, volcanoes release carbon dioxide and sulfur dioxide, and decrease stratospheric concentrations of ozone, thus producing a potential warming effect (Source: Mintzer, 1992); The set of geological processes that result in the expulsion of lava, pyroclastics, and gases at the Earth's surface; vulcanism
