- A volcano is a vent or chimney which transfers molten rock known as magma from depth to the Earth's surface. Magma erupting from a volcano is called lava and is the material which builds up the cone surrounding the vent. A volcano is active if it is erupting lava, releasing gas or generates seismic activity.

- A volcano is a landform created by magma from the earth's interior which penetrates through weaknesses in the Earths surface. Most volcanoes are formed at plate boundaries. They are classed in one of three categories of activity: active, dormant or extinct.

Volcano 508 pages on this wiki. A Volcano is an opening (or rupture) in the Earth's surface or crust, which allows hot, molten rock, ash, and gases to escape from deep below the surface. Volcanic activity involving the extrusion of rock tends to form mountains or features like mountains over a period of time.An erupting volcano.ivergent plate boundaries Edit. At the mid-oceanic ridges, two tectonic plates diverge from one another. New oceanic crust is being formed by hot molten rock slowly cooling down and solidifying. In these places, the crust is very thin and eruptions occur frequently because of the pull by the tectonic plates.

Definitions Lava. Magma which has reached the surface through a volcanic eruption. The term is most commonly applied to streams of liquid rock that flow from a crater or fissure. It also refers to cooled and solidified rock.ompound Volcano. A volcano that consists of a complex of two or more vents, or a volcano that has an associated volcanic dome, either in its crater or on its flanks. Examples are Vesuvius and Mont Pelee.

Volcanic gases can be harmful to health, vegetation and infrastructure. Hydrogen halides (HF, HCl, HBr) are strong, toxic acids. When magma ascends close to the surface, volcanoes can emit the halogens fluorine, chlorine and bromine in the form of hydrogen halides (HF, HCl and HBr).

- Often times the same type of radar imagery is used to reconstruct the changes throughout a volcanic eruption, this radar imagery service is also used on the Yellowstone Super Caldera. Examples of how this has been used can be seen on both the Hawaii Volcanoes Observatory website and Yellowstone Volcano Observatory website. (See related links).

Glossary of Geography Terms and Definitions A volcano is a landform (usually a mountain) where molten rock erupts through the surface of the planet. In simple terms a volcano is a mountain that opens downward to a pool of molten rock (magma) below the surface of the earth. It is a hole in the Earth from which molten rock and gas erupt.

Types of Volcanic Eruptions Here are some of the most common types of eruptions: In a Hawaiian eruption, fluid basaltic lava is thrown into the air in jets from a vent or line of vents (a fissure) at the summit or on the flank of a volcano.The jets can last for hours or even days, a phenomenon known as fire fountaining. Vulcanian eruption is a short, violent, relatively small explosion of viscous magma (usually andesite, dacite, or rhyolite). This type of eruption results from the fragmentation and explosion of a plug of lava in a volcanic conduit, or from the rupture of a lava dome (viscous lava that piles up over a vent).

Anatomy of an Underwater Volcano Definition A volcano is a rupture in the planet's crust through which molten rock, ash and gas escape. The opening at the top of the volcano is known as the crater. Although often associated with the ring of fire in the pacific, Volcanoes can form at any location where there is a thinning of the earth's crust.

Volcano Facts and Types of Volcanoes A volcano is a vent or fissure in Earth's crust through which lava, ash, rock and gases erupt. A volcano is also a mountain formed by the accumulation of these eruptive products.Let's take a look at how volcanoes form: Earth's crust is 40 to 250 miles (64 to 402 kilometers) thick. volcano is a vent or fissure in Earth's crust through which lava, ash, rock and gases erupt.

- Definition of a volcano: A volcano is the term for any place on the surface of the earth, where hot molten rock (magma) reaches the surface. Current activity of Bardarbunga volcano, Iceland: An intense seismic crisis started at Bárdarbunga volcano on 16 August 2014 and is continuing at the time of writing (23 Aug).

- Title Slide. Slide 2. A volcano is a place on the Earth’s surface where hot, molten rock (called magma) breaks through. As we will see there are many different types of volcanoes and material that is erupted. volcanic eruption dominated by the passive outpouring of lava onto the Earth’s surface is called an effusive eruption. This happens either because there is not enough gas (volatiles) in the magma to break it apart upon escaping, or the magma is too viscous (sticky) to allow the volatiles to escape quickly.

- Volcanoes and Humans. Mudflows are somewhat of a misnomer, because these volcanic flows include not only mud, but debris ranging up to boulder size. The term, however, has been commonly applied to water-saturated volcanic flows and is well entrenched in the literature.The Indonesian word lahar refers to mudflows in volcanic terrain.udflows are somewhat of a misnomer, because these volcanic flows include not only mud, but debris ranging up to boulder size.

Volcanic neck Volcanic neck. Definition: a hill resulting from differential weathering and erosion between the former feeder tube of a volcano and its surrounding rocks. A volcanic plug, also called a volcanic neck or lava neck, is a volcanic landform created when lava hardens within a vent on an active volcano. When forming, a plug can cause an extreme build-up of pressure if volatile-charged magma is trapped beneath it, and this can sometimes lead to an explosive eruption.

Volcano A volcano is a rupture on the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle. volcano is a rupture on the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

Volcanic arc A volcanic arc is a chain of volcanoes formed above a subducting plate, positioned in an arc shape as seen from above.Offshore volcanoes form islands, resulting in a volcanic island arc.Generally they result from the subduction of an oceanic tectonic plate under another tectonic plate, and often parallel an oceanic trench.The oceanic plate is saturated with water, and volatiles such as water drastically lower the melting point of the mantle.ffshore volcanoes form islands, resulting in a volcanic island arc. Generally they result from the subduction of an oceanic tectonic plate under another tectonic plate, and often parallel an oceanic trench.
