13. Does Earth have lava in its center? (A K2S Question)

From The Space Library

Earth does not have lava in its center. When there are volcanic eruptions, the lava comes from hot spots just below the surface. This heat is the remains of the energy that came when the Earth was formed at the outset by the crashing together, because of gravity, of its early materials. At the center of the Earth, scientists think there is a giant ball of molten iron.
