The Mohorovičić discontinuity, also known as the Moho, is the boundary between the Earth's crust and the mantle. It is named after Croatian seismologist Andrija Mohorovičić, who first discovered it in 1909. The Moho is characterized by a sudden increase in seismic wave velocity, indicating a change in composition and density between the crust and mantle.
On the other hand, the Gutenberg discontinuity is the boundary between the Earth's mantle and outer core. It is named after German seismologist Beno Gutenberg, who first identified it in 1913. The Gutenberg discontinuity is characterized by a sudden decrease in seismic wave velocity, indicating a change in composition and density between the mantle and outer core.
In summary, the Mohorovičić discontinuity marks the boundary between the Earth's crust and mantle, while the Gutenberg discontinuity marks the boundary between the mantle and outer core.

Mohorovičić Discontinuity (Moho)
- Boundary between the Earth's crust and mantle
- First identified by Andrija Mohorovičić in 1909
- Characterized by a sharp increase in seismic wave velocity
- Depth varies from 5-70 km
Gutenberg Discontinuity
- Boundary between the Earth's mantle and core
- First identified by Beno Gutenberg in 1914
- Seismic waves do not penetrate beyond this boundary
- Located at a depth of approximately 2900 km
Key Differences:
- Location: Moho marks the crust-mantle boundary, while Gutenberg marks the mantle-core boundary.
- Seismic Wave Behavior: P-waves (compressional) increase in velocity at the Moho, while they are refracted and reflected at the Gutenberg. S-waves (shear) are not transmitted beyond the Gutenberg.
- Composition: The Moho reflects changes in crustal composition, while the Gutenberg separates the rocky mantle from the molten core.
- Depth: The Moho varies in depth, while the Gutenberg is consistently located at around 2900 km.
- Identification: The Moho is detectable by seismic analysis, while the Gutenberg is identified by the absence of seismic energy beyond its boundary.
