Mohorovičić discontinuity - Wikipedia

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.

See more The Mohorovičić discontinuity , usually referred to as the Moho discontinuity, Moho boundary, or just Moho, is the boundary between the Earth's crust and the mantle. It is defined by the distinct change in velocity of See more Croatian seismologist Andrija Mohorovičić is credited with discovering and defining the Moho. In 1909, he was examining data from a local earthquake in Zagreb when he observed two distinct sets of P-waves and S-waves propagating out from the focus of the earthquake. … See more • Britt, Robert Roy (2005-04-07).
