Lava Tube

Lava Tube

Lava tubes are natural conduits through which lava travels beneath the surface of a lava flow, expelled by a volcano during an eruption. They can be actively draining lava from a source, or can be extinct, meaning the lava flow has ceased and the rock has cooled and left a long, cave-like channel.

Lava tubes are likely to exist on previously or currently geologically active planets or moons, including the Earth.

Famous quotes containing the words tube and/or lava:

    One of the great natural phenomena is the way in which a tube of toothpaste suddenly empties itself when it hears that you are planning a trip, so that when you come to pack it is just a twisted shell of its former self, with not even a cubic millimeter left to be squeezed out.
    Robert Benchley (1889–1945)

    We walk on molten lava on which the claw of a fly or the fall of a hair makes its impression, which being received, the mass hardens to flint and retains every impression forevermore.
    Ralph Waldo Emerson (1803–1882)
