Detailed explanation-1: -The Mohorovičić discontinuity, also known as the Moho, is a discrete jump in seismic wave velocities – a seismic discontinuity – that has come to define the boundary between the crust and the mantle. Its significance stems from its clear demarcation of the first boundary of the chemically differentiated solid Earth.
Detailed explanation-2: -The Moho discontinuity is the boundary between the Earth’s crust and the mantle. It has been named so because it was discovered by a Croatian scientist, Andreaja Mohorovicic. This boundary marks a change in seismic-wave velocity from the crust to the uppermost mantle within the (lithospheric) plate.
Detailed explanation-3: -The boundary between the crust (continental or oceanic) and the underlying mantle is known as the Mohorovičić discontinuity (also called Moho), which is named for its discoverer, Croatian seismologist Andrija Mohorovičić.
