1. (Geological Science) the boundary between the earth's crust and mantle, across which there is a sudden change in the velocity of seismic waves. Often shortened to: Moho. [C20: named after Andrija MohoroviÄiÄ (1857-1936), Croatian geologist].
What is the MohoroviÄiÄ Discontinuity? The Mohorovicic Discontinuity, or Moho, is the boundary between the crust and the mantle. 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 depth of about 32 kilometers beneath the continents. At this discontinuity, seismic waves accelerate.
