Geology
  • 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.’
