- Lava - Wikipedia
Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from 800 to 1,200 °C (1,470 to 2,190 °F) The volcanic rock resulting from subsequent cooling is often also called lava A lava flow is an outpouring of lava during an effusive eruption
