Volcanic Neck
This is known as a volcanic plug or neck. Please see the related link for more information.
Solid materials erupted from a volcano are known as pyroclastic materials. These include ash, rocks, and hardened lava fragments that can vary in size from tiny particles to large boulders. Pyroclastic materials are formed during explosive volcanic eruptions when magma is fragmented and violently expelled from the volcano.
The main solid parts of a volcano include the crust of the Earth, the volcanic rock that forms the cone and vent of the volcano, and the hardened lava flows. Beneath the surface, there are also solid magma chambers where molten rock accumulates before erupting.
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.

Lava is a liquid although some parts of it may have already solidified.
Yes, volcanoes and density are related. Magma created by the melting of rocks in the Earth's mantle is less dense than the surrounding solid rock, causing it to rise towards the surface and eventually erupt as a volcano. The composition and temperature of the magma play a role in determining how explosive or effusive a volcano will be.
