The moho marks what type of boundary
WebAug 8, 2016 · The Moho is widely believed to be the boundary between Earth’s crust and an underlying layer of denser rocks in Earth’s interior called the mantle. It is named after Croatian seismologist Andrija Mohorovicic, who first detected it in 1909 by examining seismic waves moving through the Earth. WebThe Mohorovicic Discontinuity, commonly called the “Moho” is recognized as the boundary zone between Earth's crust and the mantle. This boundary marks a change in seismic-wave velocity from the crust to the uppermost …

Did you know?
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 … See more The Mohorovičić discontinuity , usually referred to as the Moho discontinuity, Moho boundary, or just Moho, is the boundary between the Earth's crust and the mantle.

The curves show the paths of waves, and the lines crossing the rays show mark the wavefront at one minute intervals. WebMoho, or Mohorovičić discontinuity, boundary between the Earth’s crust and its mantle. The Moho lies at a depth of about 22 mi (35 km) below continents and about 4.5 mi (7 km) beneath the oceanic crust. Modern instruments have determined that the velocity of seismic wave s increases rapidly at this boundary.

WebSince magma is a mixture of different minerals, the solidus boundary is more of a fuzzy zone rather than a well-defined line; some minerals are melted and some remain solid. This type of rock behavior is called partial melting and represents real-world magmas, which typically contain solid, liquid, and volatile components. isight replacement utilityWebNov 19, 2014 · Introduction.
