WebKeep in mind that while the Moho averages about 10km deep beneath oceanic crust, it can be as much as 70km deep beneath continental crust. Earth’s crust and mantle, Moho discontinuity between bottom of crust and solid uppermost mantle The Moho’s depth varies depending upon geographic location. WebOften referred to as simply the Moho, this crust-mantle interface lies at a depth of about 35 km (22 miles) on continents and about 7 km (4.3 miles) beneath the oceanic crust. Modern instruments have determined that seismic wave velocity rapidly increases to more than 8 km (5 miles) per second at this boundary.
WebApr 10, 2024 · Moho depths vary from a maximum of >20 km at the continental margin to about 5 km at the southern rift axis (Figure 3a). Along the rift axis, Moho rises under the troughs and deepens under inter-trough zones. Moho also deepens northwards, consistent with the northward propagation of the Red Sea Rift (Figure 3a). The Moho marks the transition in composition between the Earth's rocky outer crust and the more plastic mantle. Immediately above the Moho, the velocities of primary seismic waves (P-waves) are consistent with those through basalt (6.7–7.2 km/s), and below they are similar to those through peridotite or dunite (7.6–8.6 km/s). This increase of approximately 1 km/s corresponds to a distin…
WebThe Moho is the name of the line separating the mantle from the core. This claim is untrue. The core-mantle border, not the Moho, is the term used to describe the boundary between the mantle and the core. The line separating the Earth's crust and mantle is known as the Moho.
