Volcanic Neck
magma is the semi-solid that comes out of the volcano
This is known as a volcanic plug or neck. Please see the related link for more information.
When a volcano erupts it releases liquid magma into the air and as it falls to the earth it cools down and becomes solid.
Magma is underground, when it reaches the surface it becomes lava. So solidified magma is really lava. The lava flow is the liquid lava as it goes down the mountain, when hard its just hardened lava.

Being a less dense liquid, it rises toward the surface, seeking the path of least resistance. The volcano is simply a structure created by the rising magma and the surface features of its lava.

Devils Tower in Wyoming is an exposed pipe of an old volcano. It is over 700 feet high and composed of solid rock.
The Core of the Volcano is actoly the Core of the Earth as Volcano's basicly the earths Air shafts

The magma from the Earth's mantle can rise and collect in spaces called magma chambers. The magma continues to collect here until it is pushed out of a crack in the ground or a volcano.

This is a silly question...No! Magma (not lava) can melt (not burn) and include some material sorrounding it but could never melt an entire volcano as it would cool down and become solid in doing so.

No. Some melting of rock occurs in and under a volcano from the magma, but it is only a small fraction of the volcano's rock. There are two reasons for both stemming from the first law of thermodynamics: energy can neither be created nor destroyed, only converted between different forms. This means that for magma or lava to heat up and melt a rock, the lava itself must cool down. In terms of temperature, the magma in a volcano is closer to solidifying than the rock is to melting. Second, the volume of solid rock in a volcano is much larger than the volume of magma.
No. Silica, or silicon dioxide, is a component of magma and most rocks on earth. It is a solid under most conditions but will form part of the liquid melt of magma. Pure silica in mineral form is called quartz.
