the zone which separates the crust from the mantle. Average depth 35km. Usually seismically defined.

is the junction which separates the Earth's crust and mantle. Its depth is about 10 kilometres below the ocean basin. neutrinos, see nuclear fusion

The boundary between the crust and the mantle. Frequently referred to as the Moho.

The first global seismic discontinuity below the surface of the Earth. It lies at a depth varying from about 5 to 10 m beneath the ocean floor to about 35 km beneath the continents. Commonly referred to as the Moho.

a seismic discontinuity thought to represent the boundary between the crust and the mantle. Typically 35 km below the surface of the continents and 5-11 km below the ocean floor.

The boundary surface or sharp seismic-velocity discontinuity (pronounced Mo-ho-ro-vi-chich) that separates the Earth's crust from the underlying mantle. Named for Andrija Mohorovicic, the Croatian seismologist who first suggested its existence. Under Eastern Canada, it can be found at around 40 km depth.

The boundary within the earth between the crust and the mantle, as indicated by the refraction and velocity change of seismic waves recognized by Andrija Mohorovicic. The depth of the Mohorovicic Discontinuity is ~5-7 km below oceanic crust and ~10-70 km below continental crust.
