molten rock

Sometimes magma reaches the surface through volcanoes. Then the molten rock is called lava.

as I said previously the molten rock material is called magma if it is beneath the surface and called lava if it is on the surface.

The reservoir is under such pressure that it has forced tongues of molten rock up towards the surface, producing eruptions and earthquakes.
