The Moho
The top of the mantle is defined by a sudden increase in seismic velocity, which was first noted by Andrija Mohorovičić in 1909; this boundary is now referred to as the "Mohorovicic discontinuity" or "Moho". Its depth ranges from about 5 km beneath the ocean floor to about 35 km below the continent, although it may reach 60 km or more under some mountain ranges.
The sometimes magnesium rich Mohorovičić discontinuity, which often is called simply 'Moho', forms the boundary between the basalt rich crust and the planet's underlying, iron rich mantle.

The discovery of the MohoroviÄiÄ discontinuity (Moho) was based on the analysis of seismic waves that travel through the Earth. Scientists observed a change in the velocity of seismic waves at a certain depth, indicating a boundary between the Earth's crust and mantle. This discovery provided valuable insights into the structure and composition of the Earth's interior.
Andrija Mohorovicic discovered the Moho boundary, or Mohorovicic discontinuity, in 1909 by observing the travel times of seismic waves. He noticed a sudden increase in seismic wave velocity at a certain depth in the Earth's interior, which indicated a change in composition and density between the Earth's crust and mantle. This boundary was later named after Mohorovicic in recognition of his discovery.
The Mohorovicic Discontinuity, or 'Moho', was discovered in 1909 by Croatian seismologist Andrija Mohorovicic through the analysis of seismic waves. By observing the sudden increase in seismic wave velocity at a certain depth within the Earth, Mohorovicic identified the boundary between the Earth's crust and mantle, now known as the Moho.
Seismic waves generally speed up as they travel downward and reach the Moho, the boundary between the Earth's crust and mantle. This increase in speed is due to the change in density and composition of the Earth's layers, causing the waves to travel faster in the more rigid mantle layer compared to the crust.
The Mohorovicic Discontinuity (also known as the Moho) separates the Earth's crust from the underlying mantle. It is the boundary where seismic waves change speed, indicating a change in composition and density between the two layers.

the Mohorovicic (Moho) discontinuity
When seismic waves hit the Moho (MohoroviÄiÄ discontinuity), they can either be reflected back to the surface, refracted as they pass through the boundary, or converted into a different type of wave. This boundary separates the Earth's crust from the underlying mantle, resulting in changes in seismic wave behavior.
The MohoroviÄiÄ discontinuity, also known as the Moho, marks the boundary between the Earth's crust and mantle. It is identified by a sudden increase in seismic wave velocities, indicating a change in rock density and composition at this boundary.
