• Mohorovičić Discontinuity The Moho Geology

    What is the Mohorovičić Discontinuity? The Mohorovicic Discontinuity, or "Moho," is the boundary between the crust and the mantle. The red line in the diagram shows its location. In geology the word "discontinuity" is used for a surface at which seismic waves change velocity. One of these surfaces

  • What Is the Difference Between the Crust & the Lithosphere

    Apr 25, 2017 · When discussing the composition of the Earth as a whole, geologists conceptually divide the Earth into several layers. One of these layers is the crust, which is the outermost part of the planet. The lithosphere is not an individual layer, but rather a zone made up of two of the layers of the Earth, which includes the

    Jan 14, 2019 · M-type (mantle) granites are rarer and are thought to have evolved directly from deeper melts in the mantle. A-type (anorogenic) granites now appear to be a special variety of I-type granites. The evidence is intricate and subtle, and the experts have been arguing for a long time, but that is the gist of where things stand now.

    The most efficient way for this heat to escape Earth's interior is through some type of slow convection of mantle rock in which hot rock from the interior rises toward the surface, loses heat to the overlying lithosphere, becomes denser as it cools, and then sinks back into the interior where it is heated, and the process repeats itself.

    Constructive plate boundaries are underlain by regions of hot mantle that rises in response to the separation of the overlying plates and so it is easy to see how magma can be generated from the mantle. Beneath island arcs there is less evidence for hot mantle and so melting must be triggered by some alternative mechanism.
