Web2 days ago · This “subducted” oceanic material could collect along the core-mantle boundary where it can be pushed by the slowly flowing rock in the mantle over time. “Analyzing thousand of seismic recordings from Antarctica, our high-definition imaging method found thin anomalous zones of material at the boundary everywhere we probed. 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…
