the crust is made up of solid rock and mantle is made up of molten rocks
outer core
The mantle is the hot rock.
The mantle is the source of molten rock. This molten material can, if the tectonics are right, penetrate up through the solid outer mantle and the crust to deliver lava, which is molten rock (magma) that has reached the surface of the earth.
Partially molten, plastic like, flowing layer located below the solid part of Earth's mantle is the Asthenosphere. The asthenosphere is mechanically weak and ductiley deforming region of the upper mantle.

outer core
the earth's inner core is solid, and the crust is solid, obviously, because we can walk on it.
The densest layer of the earth is the inner core.

First: The earths core is not molten, it is a very dense solid mass, kept solid by the intense pressure on it. Second: It is the layer around this core that is molten, and yes it does influence gravity, but more so earths magnetism.
The outer core is the only layer with molten in it.
The asthenosphere is partially molten. It is about 5% molten.

All the layers of the Earth are solid except for the outer core which is comprised of molten iron and nickel.
