... A volcano is a location on the surface of the Earth where magma has erupted out of the interior of the planet. Magma is molten rock, which has melted from the extreme heat (2200°C to 5000°C) and pressure that exists inside the Earth. Once molten rock has erupted onto the Earth’s surface, it is calle ...
