This is the description for the conduit of a volcano. Use the link below for more information, including a diagram.

Dont listen to that because that's not true its the pipe and if it's not that then its the vent:)

What hardens and cools beneath earth's surface when an intrusive igneous rock forms?

The substance that cools beneath the earths surface when an intrusive igneous rock forms is Magma. Magma is a molten material made up of rocks and minerals.


Why do large particles form on Intrusive rocks?

Intrusive rocks are formed below the ground in a magma chamber. Being that the chamber is underground, it takes a long time to cool. This allows the rock forming minerals to "grow" to their size. On the other hand, lava (which is what magma is called when it is above ground and is deemed extrusive) will cool much faster when expose to the air. Therefore, minerals do not have the time to "grow" to a large size.


How long does it take for magma to reach the Earth's surface?

In the normal course of things, lava doesn't usually reach the surface of the earth, it being encased by the earth's solid rock mantle and the earth's crust. However, when fault lines and cracks develop, the lava, under great pressure, spews forth from deep inside the earth in a matter of seconds. In sub-surface lava channels it is reckoned that lava can flow at about 60 kilometers per hour or so, but the time it takes to reach the surface depends on how deep beneath the surface the particular channel is situated. Pyroclastic surges (mainly gas, plus some lava), can reach speeds arounds 350 km/h. However, one cause of these is the undergraound lava coming into water at some point before its eruption, particularly when the lava vent it situated under the sea. Of course, scientists are continually monitoring movements of the earth's layers and are quick to alert us to any potential dangers, particularly in areas known to be at risk.

What minerals combine to form igneous rock?

It doesn't necessarily matter what the minerals are, as long as they form from cooling magma or lava. Igneous rocks are formed by the solidification of cooled magma (molten rock). They may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.


How do fissures form?

Fissures form when rocks are under stress and begin to crack or fracture, often due to tectonic activity, volcanic activity, or changes in temperature and pressure. These cracks can develop into long, narrow openings in the Earth's surface, allowing magma or fluids to move towards the surface.

The magma moves upward through a pipe, witch is a long tube that connects the magma chamber to the surface.Molten rocks and gas through it's opening called a vent.It's all written here in a text book called Prentice Hall Earth Science. This information is at page 210.


How long can a volcano last?

Until the magma chamber feeding it runs out of magma.


Definition of branch pipe of a volcano?

A branch pipe of a volcano is a smaller conduit that branches off from the main vent of the volcano. Branch pipes can be found on the flanks of a volcano and may act as secondary pathways for magma to reach the surface. They can contribute to localized eruptions and can play a role in the overall plumbing system of a volcano.


What is a branch pipe of a volcano?

A pipe is a long tube in the ground that connects the magma chamber to the earths surface.


Can rising magma change composition before reaching the surface?

Yes. If the magma stops in a magma chamber long enough it can change composition through two mechanisms:fractional crystalization, where minerals with lower melting points crystallize and sink to the bottom og the chamberMelting of srrounding rock, which then become part of the magma.


What is the hole called when lava comes out of it?

Do you mean the hole it comes out of the ground through? That is a volcano. More likely, you mean the hole made when the lava starts to cool and the liquid part inside can suddenly run out. That is a lava tube.


How does magma leave a volcano?

Magma collects in a magma chamber.the magma moves upward through a pipe, a long tube in the ground that connects the magma chamber to earths surface. Molten rock and gas leave the volcano through an opening called a vent. A lava flow happens when an are covered by lava pours out of the vent. A crater is a bowl shaped area at the top of the volcano around the central vent where magma comes out. Magma is beneath the volcano. Lava is the name of magma after it leaves a volcano.

How long does it take the magma to complete the circular convection flow?

The time it takes for magma to complete a circular convection flow can vary depending on factors such as temperature, viscosity, and the size of the magma chamber. In general, this process can take anywhere from days to centuries.
