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:)
the tube a a volcanoe that hold lava are called lava chambers
it's the conduit

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.
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.
There are 3 main types of rocks:Igneous RocksForms when molten rock cools.2 types of molten rock: magma, and lava.Intrusion: Forms when magma cools. Intrusion rocks take longer to form because magma takes longer to cool. Magma is under the Earth's surface, and it is very hot there. Imagine how long it would take for magma to cool down somewhere a thousand degrees!Extrusion: Forms when lava cools. Extrusion don't take as long to form, because lava cools much faster than magma does. Lava is at the surface, and the surface is WAY cooler than underground.Sedimentary RockForms when rocks/minerals/remains of plants or animals settle and accumulate.Forms in layers.3 types of sedimentary rock:Clastic - forms from accumulation of rock fragments and minerals.Biologic - forms from plant or animal remains.Chemical - forms when minerals precipitate out of a solution.MetamorphicPreexisting rocks that have changed form by heat and pressure.If you are looking for specific types, here are some brief examples:Igneous RocksBasaltPegmatiteGraniteTuffSedimentary RocksLimestoneCoalShaleSiltstoneMetamorphic RocksSlateGneissSchistMarble
In dome mountains, uplift pushes a large body of hardened magma toward the surface. The hardened magma forces the layers of rock to bend upward in a dome shape. In a lava plateau, lava can flow out of two long cracks in an area. The thin, runny lava floods the area and travels far before cooling and solidifying.
surface waves, raleigh waves, and long waves.
pipe
A pipe is a long tube in the ground that connects the magma chamber to the earths surface.
Pipe?
Magma becomes lava after reaching a volcano's vent.Volcanoes have a pocket beneath the surface called a magma chamber. 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.
A pipe is a long tube in the ground that connects the magma chamber to the earths surface.
Until the magma chamber feeding it runs out of magma.
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. YOUre WELCome
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.
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.
As far as we know, they are not. The Mono Craters are located above and fed by a magma chamber about 8 km below. The Inyo Craters are likely fed from the same magma chamber via a north-south-trending system of fractures but may be fed by the magma chamber under Long Valley Caldera.

magma rises toward earth's surface as long as it is less dense than the surrounding rock.
