The discontinuity was discovered by Beno Gutenberga seismologist who made several important contributions to the study and understanding of the Earth’s interior. Mantle rock at surface: Physics of the Earth and Planetary Interiors. Why not have a go at them together! Articles with short description All articles with unsourced statements Articles with unsourced statements from August An introduction to seismological research: Structure of the Earth.
The Moho is characterized by a transition zone of up to m thick. P-wave velocities are much slower in the outer core than in the deep mantle while S-waves do not exist at all in the liquid portion of the core. Geophysics Structure of the Earth.
Mohorovičić Discontinuity – The Moho
Information about ore minerals, gem materials and rock-forming minerals. Dictionary Conjugation Phrases Games More by bab.
In geology the word “discontinuity” is used for a surface at which seismic waves change velocity. Find Other Topics on Geology. English name of the letter D. Do you want to translate into other languages? Earth and Planetary Science Letters. We may not have made it to our goal of m, but we did drill the deepest ever single-leg hole into hard rock mwhich is currently the 5th deepest ever drilled into the hard ocean crust.
discontinuidad de Mohorovicic – English translation – Spanish-English dictionary
Note how the thickest areas red and dark brown are beneath some of Earth’s important mountain ranges such as the Andes west side of South AmericaRockies western North AmericaHimalayas north of India in south-central Asiaand Urals north-south trending between Europe and Asia. Disconntinuidad Moho lies almost entirely within the lithosphere ; only beneath mid-ocean ridges does it define the lithosphere— asthenosphere boundary.

Recent evidence suggests a distinct boundary layer directly above the CMB possibly made of a novel phase of the basic perovskite mineralogy of the deep mantle named post-perovskite.
The lower density material immediately beneath the surface is now commonly referred to as “Earth’s crust. Highest mohorlvicic, deepest lake, biggest tsunami and more.
There are a few rare locations where mantle material has been brought to the surface by tectonic forces. His system was to label discontinuidac layer alphabetically, A through G, with the crust as ‘A’ and the inner core as ‘G’. This page was last edited on 23 Decemberat Boundary between the Earth’s crust and the mantle. Near-surface observations suggest such sorting produces an irregular surface.
Drilling to the Moho through oceanic crust has also been unsuccessful. S waves shear material, and cannot transmit through liquids, so it is thought that the unit above the discontinuidsd is solid, while the unit below is in a liquid or molten form. Statements consisting only of original research should be removed.
Conrad continental crust Gutenberg upper mantle Lehmann upper mantle.
A seismic discontinuity occurs within Earth’s interior at a depth of about 2, km 1, mi below the surface, where mohodovicic is an abrupt change in the speed of seismic waves generated by earthquakes or explosions that travel through Earth. Seismic tomography studies have shown significant irregularities within the boundary zone and appear to be dominated by the African and Pacific large low-shear-velocity provinces LLSVPs.
Mohorovičić discontinuity – Wikidata
Moborovicic boundary is observed via the discontinuity in seismic wave velocities at that depth due to the differences between the acoustic impedances of the solid mantle and the molten outer core.
The deepest well that has been drilled to date was located on the Kola Peninsula of the Soviet Union. Retrieved from ” https: Views Read Edit View history.
A photo of rock from one of these locations is shown on this page. The dixcontinuidad section of the outer core is thought to be about —1, K hotter than the overlying mantle, creating a thermal boundary layer. Retrieved from ” https: At this discontinuity, seismic waves accelerate. During the late s and early s the executive committee of the U. The red line in the discontinuudad shows its location. No one has ever been deep enough into the Earth to see the Moho, and no wells have ever been drilled deep enough to penetrate it.
