From what I understand, most of the earth's mantle is not molten and you can only find molten rock, magma, in some specific places like mid-ocean rifts and volcanic hotspots. The mantle has convection currents, but those flow on geological timescales. The Earth's outer core is liquid, but that's almost three thousand kilometers below the surface.
