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 seismic waves as they pass through changing densities of rock. The Moho lies almost entirely … See more The Moho marks the transition in composition between the Earth's rocky outer crust and the more plastic mantle. Immediately above the Moho, the velocities of primary seismic waves (P-waves) are consistent with … See more Croatian seismologist Andrija Mohorovičić is credited with discovering and defining the Moho.
