Mohorovicic Discontinuity or Moho

Explanation:

It was discovered by seismologist Andrija Mohorovicic. The Moho starts from the depth of 3232 kmkm and at the upper part of the mantle.

This was discovered when Andrija Mohorovicic noticed that there is a change in the movement of the seismic waves. The change in movement indicates that seismic waves move at a different composition of the Earth's layer and that is the Moho.
