The solid structure created when lava, gases, and hot particles escape to the Earth's surface through vents. Volcanoes are usually conical. A volcano is "active" when it is erupting or has erupted recently. Volcanoes that have not erupted recently but are considered likely to erupt in the future are said to be "dormant." A volcano that has not erupted for a long time and is not expected to erupt in the future is "extinct."
A naturally occurring vent or fissure at the Earth's surface through which erupt molten, solid, and gaseous materials. Volcanic eruptions inject large quantities of dust, gas, and aerosols into the atmosphere. A major component of volcanic clouds is sulfur dioxide, a strong absorber of ultraviolet radiation. Chemical interactions between sulfur dioxide and water cause sulfuric acid aerosols which can scatter some of the incident solar radiation back to space, thus causing a global cooling effect. For example, Mt. Pinatubo in the Philippines erupted in June 1991, and in the following year the global surface temperature was observed to decrease by about 0.3 degrees C.
vent or chimney to the earth's surface from a resevoir of molten matter, known as magma, in the depths of the crust of the earth;150 The mountain formed by local accumulation of volcanic materials around an erupting vent.151
a geological landform where magma (rock from the Earth's interior made molten 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
a transforming process that fixes the surface of the world in mountains (in conjunction with other forces, such as plate tectonics and weather, and having other effects as well, such as forming lava fields, etc
A vent or fissure in the Earth's surface through which molten lava, ash, and gases are ejected. It is also the name for the structure, usually conical, formed by the materials ejected from the vent or fissure.
An erupting volcano means you are ignoring a dangerous situation that is now coming to a head. A smoking volcano predicts a love affair made in deceit. An inactive volcano is a warning to not take on any new ventures for a while.
is a naturally occurring vent or fissure at Earth's surface through which erupt molten, solid, and gaseous materials. Volcanic eruptions inject large quantities of dust, gas, and aerosols into the atmosphere and can thus cause temporary climatic cooling.
A volcano is a place on the Earth's surface (or any other planet's or moon's surface) where molten rock, gases and pyroclastic debris erupt through the earth's crust. Volcanoes vary quite a bit in their structure - some are cracks in the earth's crust where lava erupts, and some are domes, shields, or mountain-like structures with a crater at the summit. Some types of volcanoes include: caldera, cinder cone, hornito, lava dome, maar, mud volcano, shield volcano, spatter cone, and stratovolcano. The word volcano is from Latin; it comes from the ancient Romans god of fire and metalworking, Vulcan.
layers of lava or ash erupted on to the surface of the Earth forming a cone-shaped structure. Volcanoes are found in areas of the Earth which are geologically unstable, such as near plate boundaries, or 'hot-spots' where magma wells-up from deep inside the Earth. Page up
Volcano is an action drama starring Tommy Lee Jones, Anne Heche, and Don Cheadle, and was directed by Mick Jackson. The film opened in the United States on April 25, 1997 just a couple months after Dante's Peak, a movie with a similar plot.
To see a volcano in your dreams, signifies that you will be in violent disputes, which threaten your reputation as a fair dealing and honest citizen. For a young woman, it means that her selfishness and greed will lead her into intricate adventures.
