Earth's crust and mantle, Moho discontinuity between bottom of crust and solid uppermost mantle. The Mohorovičić discontinuity (/ ˌ m oʊ h ə ˈ r oʊ v ɪ tʃ ɪ tʃ / MOH-hə-ROH-vih-chitch; Croatian: [moxorôʋiːtʃitɕ]) [1] – usually called the Moho discontinuity, Moho boundary, or just Moho – is the boundary between the crust and the mantle of Earth.
Project Mohole was an attempt in the early 1960s to drill through the Earth's crust to obtain samples of the Mohorovičić discontinuity, or Moho, the boundary between the Earth's crust and mantle. [2] The project was intended to provide an earth science complement to the high-profile Space Race.
This is now called the Mohorovičić discontinuity or (because of the complexity of that name) Moho. According to Mohorovičić, a layered structure would explain the observation of depths where seismic waves change speed and the difference in chemical composition between rocks from the crust and those from the mantle.
The top of the mantle is defined by a sudden increase in the speed of seismic waves, which Andrija Mohorovičić first noted in 1909; this boundary is now referred to as the Mohorovičić discontinuity or "Moho." [3] The Moho defines the base of the crust and varies from 10 km (6.2 mi) to 70 km (43 mi) below the surface of the Earth.
The North Island species (P. mantelli, as described by Owen) was known to Māori as moho; it is extinct and only known from skeletal remains and one possible specimen. Moho were taller and more slender than takahē, and share a common ancestor with living pūkeko. [15]
Moho is a genus of extinct birds in the Hawaiian bird family, Mohoidae, that were endemic to the Hawaiian Islands. Members of the genus are known as ʻōʻō in the Hawaiian language . Their plumage was generally striking glossy black; some species had yellowish axillary tufts and other black outer feathers .

Male and female Moho bishopi. It was discovered in 1892 by Henry C. Palmer, a bird collector for Lord Rothschild. Its length was about 29 centimeters. The tail had reached a length of 10 centimeters. The plumage was general glossy black with yellow feather tufts on the maxillaries, beneath the wings and the undertail coverts.
