- A supervolcano is any volcano capable of producing a volcanic eruption with an ejecta mass greater than 10 15 kg.arge igneous provinces can cover huge areas with lava and volcanic ash, causing long-lasting climate change (such as the triggering of a small ice age or global warming), which can threaten species with extinction.

Supercontinent In geology, a supercontinent is the assembly of most or all of the Earth 's continental blocks or cratons to form a single large landmass.However, the definition of a supercontinent can be ambiguous.angaea's supercontinent cycle is a good example for the efficiency of using the presence, or lack of, these entities to record the development, tenure, and break-up of supercontinents. There is a sharp decrease in passive margins between 500 and 350 Ma during the timing of Pangaea's assembly.

Stratovolcano Stratovolcano. Stratovolcanoes, or composite volcanoes, are similar to cinder cone volcanoes in terms of their shape, but that is one of their few similarities.These volcanoes have gentle lower slopes but much steeper upper slopes, creating an upwardly concave cone and generally have many distinct vents.tratovolcanoes, or composite volcanoes, are similar to cinder cone volcanoes in terms of their shape, but that is one of their few similarities.

Supermoon A supermoon is the coincidence of a full moon or a new moon with the closest approach the Moon makes to the Earth on its elliptical orbit, resulting in the largest apparent size of the lunar disk as seen from Earth. The technical name is the perigee-syzygy of the Earth-Moon-Sun system.

VENT Noun. 1. volcano-a fissure in the earth's crust (or in the surface of some other planet) through which molten lava and gases erupt. vent. crack, scissure, cleft, crevice, fissure-a long narrow opening. eructation, extravasation, eruption - (of volcanos) pouring out fumes or lava (or a deposit so formed).

Volcano 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.he most common perception of a volcano is of a conical mountain, spewing lava and poisonous gases from a crater at its summit. This describes just one of many types of volcano, and the features of volcanoes are much more complicated.

Worldâs largest âsupervolcanoâ is even bigger than previously thought World’s largest “supervolcano” is even bigger than previously thought. Seismologists have discovered a massive magma reservoir beneath the Yellowstone supervolcano in Wyoming, US, that suggests its volcanic system could be more than 5.6 times larger than was previously thought.

plume A body of magma that rises from the Earth's mantle into the crust. ◇ If a plume rises to the Earth's surface, it erupts as lava. ◇ If it remains below the Earth's surface, it eventually solidifies into a body of rock known as a pluton. An area in air, water, soil, or rock containing pollutants released from a single source. A plume often spreads in the environment due to the action of wind, currents, or gravity.

Stratovolcano: Definition, Formation & Facts This iconic shape that we commonly think of as a 'volcano' is actually a stratovolcano. In this lesson, we'll learn what a stratovolcano is, how stratovolcanoes form, and where you can find them on earth. Let's start with the basics.A stratovolcano is a conical-shaped volcano composed of steeply-dipping layers of lava, hardened ash, and other material erupted from the main volcanic vent.Stratovolcanoes are also commonly called composite volcanoes.his iconic shape that we commonly think of as a 'volcano' is actually a stratovolcano.

Supermoon A supermoon is a full moon or a new moon that approximately coincides with the closest distance that the Moon reaches to Earth in its elliptic orbit, resulting in a slightly larger-than-usual apparent size of the lunar disk as seen from Earth. The technical name is the perigee syzygy of the Earth–Moon–Sun system or more simply full Moon at perigee. The term supermoon is astrological in origin, and has no precise astronomical definition. The real association of the Moon with both oceanic ...

- supervolcano A new study may have finally resolved debate on how America's famous Yellowstone supervolcano was formed. The research conducted by scientists including Professor Ross Griffiths of the Australian National University, shows features associated with Yellowstone were caused by a volcanic hot spot affected by a subduction zone.

Supercontinent In geology, a supercontinent is the assembly of most or all of the Earth 's continental blocks or cratons to form a single large landmass. However, the definition of a supercontinent can be ambiguous.assive margins are therefore born during the break-up of supercontinents and die during supercontinent assembly. Pangaea's supercontinent cycle is a good example for the efficiency of using the presence, or lack of, these entities to record the development, tenure, and break-up of supercontinents.

Mount Unzen Volcano: Volcano, vent in the crust of the Earth or another planet or satellite, from which issue eruptions of molten rock, hot rock fragments, and hot gases. A volcanic eruption is an awesome display of the Earth’s power.

Definitions &Translations Freebase(5.00 / 1 vote)Rate this definition: A cryovolcano is a volcano that erupts volatiles such as water, ammonia or methane, instead of molten rock. Collectively referred to as cryomagma or ice-volcanic melt, these substances are usually liquids and form plumes, but can also be in vapour form.

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.

Composite volcanoes Composite volcanoes (also called stratovolcanoes) are much more explosive than shield volcanoes, the other important type of volcano. The large and generally cone-shaped volcanoes form along plate boundaries called subduction zones where one of the Earth's plates moves below another.omposite volcano magma contains more silica, SiO 2, than that of a shield volcano and is therefore stickier (more viscous). This stickiness plugs up the volcano, causing pressure to build-up.

- In 2005, BBC and the Discovery Channel produced a docudrama and documentary about Yellowstone called Supervolcano. Below, Yellowstone Volcano Observatory scientists answer questions that arose after this program aired that relate to supervolcanoes, volcanic hazards, and Yellowstone. The docudrama Supervolcano dramatically explores the impact of a large caldera-forming eruption at Yellowstone.

Dome Volcano Dome Volcano. A dome volcano is small and often forms inside the caldera of a stratovolcano. After a large eruption when large amount of magma has emptied out of the magma chamber the summit of the composite volcano collapses forming a depression.Inside the depression magma oozes out to begin forming a small lava dome.ome Volcano A lava dome is small and often forms inside the caldera of a stratovolcano.

- But residents and scientists had every reason to fret, mostly because the Yellowstone supervolcano is actually a caldera. A supervolcano is not just a big volcano. It occurs when magma continues to rise to the Earth’s crust but is unable to escape, kind of the way pressure cookers trap steam.

The effects of erosion, earthquakes and volcanoes A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers of hardened lava, tephra, pumice, and volcanic ash. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile and periodic explosive eruptions and effusive eruptions, although some have collapsed craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far due to high viscosity. The magma forming this lava is often felsic, having
