Seismic tomography provides reconstructions of thermal-density structure of the Earth’s mantle as deep as the man-tle/core boundary (CMB). For the first time, a direct image of dynamic processes, occurring inside the globe, … 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…
