Moho

 or Mohorovicic discontinuity

Boundary between the Earth's crust and its mantle. The Moho lies at a depth of about 22 mi (35 km) below continents and about 4.5 mi (7 km) beneath the oceanic crust. Modern instruments have determined that the velocity of seismic waves increases rapidly at this boundary. The Moho was named for Andrija Mohorovicic.

Moho 

(or Wuchi), the general name for a group of Tungus tribes that inhabited the territory of Manchuria and the Southern Primor’e from the fifth to the eighth centuries. A number of scholars maintain that the Moho assimilated and drove out the aboriginal Paleo-Asiatic inhabitants. In Chinese sources, the term “Moho” was used as a general name for the Sumo, Poty, Anch’eku, Funieh, Haoshi, Heishui, Paishan, and Yüehhsi tribes, whose clan systems were at different stages of disintegration. Plow cultivation, livestock breeding, hunting, fishing, pottery-making, metalworking, and weaving were well developed among the Moho.

The Moho were united in a tribal alliance. They often fought on the side of the Korean Koguryo kingdom in wars against China. At the turn of the eighth century the most developed tribe, the Sumo, founded the Chen kingdom, which became the Pohai kingdom in 712; almost all of the Moho tribes became members of this kingdom.
