Question

What is the moho discontinuity ?

Answer 1

The Mohorovičić discontinuity(Croatian pronunciation: [moxorôʋiːt͡ʃit͡ɕ]), usually referred to as the Moho, is the boundary between the Earth's crust and the mantle. ... TheMoho lies almost entirely within the lithosphere; only beneath mid-ocean ridges does it define the lithosphere–asthenosphere boundary.

Answer 2

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 exists at an average depth of 8 kilometers beneath the ocean basin and at an average depth of about 32 kilometers beneath the continents. At this discontinuity, seismic waves accelerate. This surface is known as the Mohorovicic Discontinuity or often simply referred to as the "Moho."
