Question

What is the difference between mohorovicic discontinity and gutenberg discontinuity?Atleast give three differences of both?

Answer 1

1- mohorovicic discontinuity marks boundary between upper mantle and crust while Gutenberg discontinuity marks boundary between lower mantle and outer core

2- the Gutenberg discontinuity is located about 2900 km below the earth surface whereas Mohorovicic discontinuity is 8 km below ocean floor and 30 to 50 km below typical continuents

3- Andriza Mohorovicic discovered the Mohorovicic discontinuity whereas Beno Gutenberg discovered the Gutenberg discontinuity .

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.
