- Lava is molten or partially molten rock that has been expelled from the interior of a terrestrial planet or a moon onto its surface. 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. The volcanic rock resulting from subsequent cooling is often also called lava.
A Liquid Fire ShowLava is the name given to the molten rock that erupts from volcanoes. It can reach temperatures of over 1,000 degrees Celsius and flow like a river of fire.
