Lava.
Below the surface, the molten rock is called magma; at the earth's surface it becomes lava, nothing has changed only the name of the liquid. Igneous rock is made by fire. Small wonder the magma from which igneous rock is formed can reach temperatures close to 1200 degrees Celsius.
Melted rock beneath the earth is called magma.
The Earth's crust is on the exterior, not the interior; that is why it is called the crust. It is on the outside. It is made mostly of rock, of various kinds. The rock of the crust is on average less dense than the rock of the mantle, which lies beneath the crust.

Molten rock is called magma when it is inside the earth. Its called lava when it reaches the Earth's surface.
The molten rock that is found inside the earth is usually simply called magma. It becomes lava after it leaves the volcano at the surface of the earth.
