(i)The boundary between the mantle and core at the depth of 2900 km is called Gutenberg's discontinuity. (i)The boundary between the crust and the mantle is called Mohorovicic discontinuity. (ii)It was observed by the seismologists, Beno Gutenberg in 1926.

Mohorovicic Discontinuity

Named after the pioneering Croatian seismologist Andrija Mohorovičić, the Moho separates both the oceanic crust and continental crust from underlying mantle. The Mohorovičić discontinuity was first identified in 1909 by Mohorovičić, when he observed that seismograms from shallow-focus earthquakes had two sets of P-waves and S-waves, one that followed a direct path near the Earth's surface and the other refracted by a high-velocity medium.

Gutenburg Discontinuity

The uppermost section of the outer core is thought to be about 500–1,800 K hotter than the overlying mantle, creating a thermal boundary layer.The boundary is thought to harbor topography, much like Earth's surface, that is supported by solid-state convection within the overlying mantle.[citation needed] Variations in the thermal properties of the core-mantle boundary may affect how the outer core's iron-rich fluids flow, which are ultimately responsible for Earth's magnetic field.
