The boundary surface between the earth's crust and the mantle, lying at a depth of about 6–7 miles (10–12 km) under the ocean bed and about 24–30 miles (40–50 km) under the continents.
- ‘The sharp boundary between the crust and mantle is called the Mohorovicic discontinuity or Moho.’
- ‘Wide-angle reflection and refraction seismic data can be used to image the Mohorovicic discontinuity and provide information on the velocity structure and physical properties of the crust.’
- ‘These values suggest that the Mohorovicic discontinuity remains relatively deep, 40 to 45 km, beneath western half of the transect.’
- ‘The Mohorovicic discontinuity, or Moho, the first major boundary of the earth's interior, separates the crust from the underlying mantle.’
- ‘This seismic boundary is known as the Mohorovicic discontinuity.’
1930s named after Andrija Mohorovičić (1857–1936), Yugoslav seismologist.
