Cave Types
|
Lava Cave
Lava caves are tubes that form when molten rock flows away from volcanoes. Cool air causes the rock to harden on the outside, and when all the lava has drained out, the tube becomes a cave.

|
Sea Cave
Sea caves are formed by waves crashing on rocky coastlines.
|
|
Ice Cave
Ice caves are formed by water flowing underneath glaciers of ice. Light passing through the ice makes the caves blue.
