WebThe mantle has two main parts, the upper mantle and the lower mantle. The upper mantle is attached to the layer above it called the crust. Together the crust and the upper mantle form a fixed shell called the lithosphere, which is broken into sections called tectonic plates. WebThe internal structure of Earth Earth's mantle is a layer of silicate rock between the crust and the outer core. It has a mass of 4.01 × 10 24 kg and thus makes up 67% of the mass of Earth. [1] It has a thickness of 2,900 kilometers (1,800 mi) [1] making up about 84% of Earth's volume.
