Lava flow during a rift eruption at Krafla, Iceland in 1984. 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.
A volcano is vent or opening on planetâs surface which allows molten rock called magma, volcanic ash and gas to escape out onto its surface. A volcano gives a look like a mountain from which lava erupts. The hot magma erupting from a volcano is called lava. When that lava cools down, it becomes solid and forms like a mound-like cone. In fact the mountain that we see today are nothing but solidified lava from previous volcanic eruptions. It is said that through volcanoes are earthâs way of renewing itself.
