Lava Tubes Caves may also form in volcanic rock when the surface of a lava flow hardens to form a roof over a still-flowing lava stream on or near the flank of a volcano. After the lava drains out, it leaves behind an empty ...

Caves and Karst ~ Learning Geology

As we have noted, caves in limestone usually occur as part of a network. Cave networks include rooms, or chambers, which are large, open spaces sometimes with cathedral-like ceilings, and tunnel-shaped or slot-shaped passages. Some chambers may host underground lakes, and some passageways may serve as conduits for underground streams.

Limestone ~ Learning Geology

About 10% of all sedimentary rocks are limestone. Limestone is partially soluble, especially in acid, and therefore forms many erosional landforms. These include limestone pavements, pot holes, cenotes, caves and gorges. Such erosion landscapes are known as karsts. Limestone is less resistant than most igneous rocks, but more resistant than ...
