Lava

Lava is a general term for all rocks originating in molten streams from volcanoes, includes traps, basalts, pumice, and others. The surface of a lava stream cools and hardens quickly, presenting a cellulose structure, while below the heat is retained much longer and the rock when cooled is compact and columnar or crystalline. The largest recorded lava flow was from Skaptar Jökull, Iceland, in 1783.
