Lava is the molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling. This molten rock is formed in the interior of some planets, including Earth, and some of their satellites.The source of the heat that melts the rock within the earth is geothermal energy.When first erupted from a volcanic vent, lava is a liquid at temperatures from 700 to 1,200 Â°C (1,292 to 2,192 Â°F).his molten rock is formed in the interior of some planets, including Earth, and some of their satellites.
