Answer:

Mohorovicic Discontinuity or Moho

Explanation:

It was discovered by seismologist Andrija Mohorovicic. The Moho starts from the depth of #32# #km# 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.
