How do lava tubes caves formed?
Lava tubs form as a result of pahoehoe lava flows. As one of these flows progresses, it builds of a layer of rock on top of it. eventually, thus becomes thick enough to support is own weight, and forms an insulating tube through which lava can flow.

What rock does lava form?

This is called a lava tube.
What are lava flows on a volcano?
