Moho

views updated May 11 2018

Moho (Mohorovičič discontinuity) Boundary between the Earth's crust and mantle. Identified by a sharp increase in the velocity of seismic waves passing through the Earth, it receive its name from the Croatian geophysicist Andrija Mohorovičič, who first recognised it in 1909. The velocity increase occurs because of the shift to more dense rocks in the mantle. The depth of the Moho varies from c.5km (3mi) to 60km (37mi) below the Earth's surface.
