- ‘The Mohorovicic discontinuity, or Moho, the first major boundary of the earth's interior, separates the crust from the underlying mantle.’
- ‘These values suggest that the Mohorovicic discontinuity remains relatively deep, 40 to 45 km, beneath western half of the transect.’
- ‘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.’
- ‘This seismic boundary is known as the Mohorovicic discontinuity.’
- ‘The sharp boundary between the crust and mantle is called the Mohorovicic discontinuity or Moho.’
