The Mohorovičić Discontinuity, or Moho, is a significant geological boundary that delineates the transition between the Earth's crust and the mantle. This crucial interface is not just a physical layer but a zone where major changes in material properties occur.
Named after the Croatian seismologist Andrija Mohorovičić, who first defined it in 1909, the Moho plays a critical role in our understanding of the planet's geological behavior. It is where lighter silicate minerals of the crust transition to the denser magnesium and iron-rich silicates found in the mantle. This boundary exemplifies how seismic waves travel differently through these materials, impacting earthquake research and tectonic studies.
What defines the Mohorovičić Discontinuity?
It is the boundary separating the Earth's crust from the mantle, marked by a significant increase in seismic wave velocity and a change in the composition of geological materials.
What is seismic velocity?
It refers to the speed at which seismic waves travel through different geological materials, which varies according to these materials' density and elastic properties.
Who is the Mohorovičić Discontinuity named after?
It is named after Croatian seismologist Andrija Mohorovičić, who identified it in 1909.
