Igneous rock
Ingenious rocks form when molten material under the earths surface cools. Not only does the molten cool it does not harden.

Magma is inside the volcano, and it becomes lava when it comes out. :)

That would be magma. The moment it reaches the surface, it becomes lava and eventually cools to form igneous rock.

Molten material below ground is called magma, and molten material above ground is called lava.

This is false. Molten material below earth's surface is known as magma. It is only known as lava once it has been erupted onto the surface.
Volcanism is the process by which molten rock material is moved from one part of the earth's crust to another, or from within the earth's crust to the surface. This molten material is called *magma* while it is still beneath the surface, but it is called *lava* as soon as it reaches the surface. All this molten rock material eventually cools and solidifies into igneous rock.
The molten material that reaches earth's surface is lava :)
