Mohorovicic Discontinuity – The Moho

Earth and Planetary Science Letters. The Mohorovicic Discontinuity marks the lower limit of Earth’s crust. The core—mantle boundary CMB in the parlance of solid earth geophysicists of the Earth lies between the planet’s silicate mantle and its liquid iron – nickel outer core.

Plate tectonics Structure of the Earth Croatian inventions. Retrieved from ” https: The discontinuity was discovered by Beno Gutenberga seismologist who made several important contributions to the study and understanding of the Earth’s interior. It was drilled to a depth of about 12 kilometers. Statements consisting only of original research should be removed.

There are a few rare locations where mantle material has been brought to the surface by tectonic forces. Mohorovicic realized that the velocity of a seismic wave is related to the density of the material that it is moving through.

Mohorovičić discontinuity – Wikidata

The Moho is characterized by a transition zone of up to m thick. He discovered that the oceanic crust has a relatively uniform thickness, while continental crust is thickest under mountain ranges and thinner under plains. Mohorovicic was able to use his discovery to study thickness variations of the crust. The 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.

Immediately above the Moho, the velocities of primary seismic waves P-waves are consistent with those through basalt 6.

Maps Volcanoes World Maps. The acceleration must be caused by a higher density material being present at depth. Boundary between the Earth’s crust and the mantle. 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.

One proposal considers a rock-melting radionuclide-powered disdontinuidad with a heavy tungsten needle that can propel itself down to the Moho discontinuity and explore Earth’s interior near it and in the upper mantle.

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.

Please improve it by verifying the claims made and adding inline citations. However the operation, named Project Moholenever received sufficient support and was mismanaged [ citation needed ] ; the United States Congress canceled it in An disconntinuidad to seismological research: He interpreted the acceleration of seismic waves observed within Earth’s outer shell as a compositional change within the Earth.


Core–mantle boundary

A seismic discontinuity occurs within Earth’s interior at a depth of about 2, km 1, mi below the surface, where there is an abrupt change in the speed of seismic waves generated by earthquakes or explosions that travel through Earth. The Mohorovicic Discontinuity, or “Moho,” is the boundary between the crust and the mantle.

Drilling to the Moho through oceanic crust has also been unsuccessful. Articles about geysers, maars, deltas, rifts, salt domes, water, and much more!
