The Mohorovičić discontinuity (/ ˌmoʊhəˈroʊvɪtʃɪtʃ / MOH-hə-ROH-vih-chitch; Croatian: [moxorôʋiːtʃitɕ]) [1] – usually called the Moho discontinuity, Moho boundary, or just Moho – is the boundary between the crust and the mantle of Earth. It is defined by the distinct change in velocity of seismic waves as they pass through ...
The meaning of MOHO is the boundary layer between the earth's crust and mantle whose depth varies from about 3 miles (5 kilometers) beneath the ocean floor to about 25 miles (40 kilometers) beneath the continents.
The Mohorovicic Discontinuity, or "Moho," is the boundary between the crust and the mantle. The red line in the diagram shows its location. In geology the word "discontinuity" is used for a surface at which seismic waves change velocity. One of these surfaces exists at an average depth of 8 kilometers beneath the ocean basin and at an average ...
Dec 3, 2023 · The Mohorovicic discontinuity is a boundary between the crust and the upper mantle. At this boundary, the P seismic wave velocity abruptly increases by nearly 1 km (0.6 mi) per second, from 6.7–7.2 km/s above it to 7.6–8.6 km/s below it. The P waves (primary or pressure) are the fastest seismic waves. They travel through fluids and solids ...

Definition. The Moho, or Mohorovičić discontinuity, is the boundary that separates the Earth's crust from the underlying mantle. It is characterized by a distinct change in seismic wave velocities, indicating a transition from the relatively rigid and less dense crust to the denser and more fluid mantle below.
