Earth's mantle is a layer of silicate rock between the crust and the outer core. It has a mass of 4.01 × 10 kg and thus makes up 67% of the mass of Earth. It has a thickness of 2,900 kilometers (1,800 mi) making up about 84% of Earth's volume. It is predominantly solid but, on geologic time scales, it behaves as a viscous fluid, sometimes described as having the consistency of caramel. Partia… WebQ. The upper layer of the mantle is said to be thicker than the lower mantle, but not solid rock like crust. The tectonic plates rest on this layer and it is responsible for the movement of those plates. What is the name of this layer? Q. The innermost layer of the Earth is thought to be made of solid iron.
