What is Lava?
Lava Molten Rock from a Volcano
Lava is molten rock that pours onto Earth's surface during a volcanic eruption. Once lava cools and solidifies it forms an igneous rock.
The only difference between lava and magma is one is molten rock below the surface of Earth, the other is molten rock after it's been expelled from the vent of a volcano.
