Do volcanoes have to be a specific type of rock for lava not to melt through?

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.

Do volcanoes have lava?
The molten rock that erupts from volcanoes ultimately comes from Earth's mantle, which is a very hot layer of rock. It is hot enough that some if its rock can melt and rise through the crust.
Does Mars have lava?
Mars does not have lava, but probably has magma due to radioactive decay.
Where is the magma stored before the eruption?
It is not. It is forced up through the Earths mantel and then through the volcano. The volcano itself is just solidified magma (called lava as it exudes from the volcano).
Will steel melt when touched by lava?
No. Lava is generally not hot enough to melt steel.
Is lava hot enough to burn through rocks?
Lava is molten rock and could melt through thin layers of rock if given enough time before cooling.
Why does ice melt in volcanoes?
Volcanoes erupt hot ash or molten rock. It is the heat from this that can melt ice.
What are volcanoes created from?
Volcanoes are created from the building up of lava flows or ash and cinder deposits. This occurs inland from subduction zones, at 'hot spots' where mantle plumes melt the lithosphere, and most often at mid ocean ridges.
What Substance do volcanoes emit or release?
Volcanoes can emit lava, ash, and rocks. I also think that they can realease sulfur and poisonous gas.
Can lava melt wolverine's claws?
Yes lava will melt everything in its path, apart from granomight witch might last at least 5 minutesin the lava.
Can lava melt concert?
of course it does lava melts everything in its way
Will you melt if you stand in lava?
No. You will burn.
Can lava melt a woodchiper?
Yes
