The correct observation made by Mohorovičić (often referred to as "Moho") is that **seismic waves travelled at varying speeds.** This is related to his discovery of the boundary between the Earth's crust and the underlying mantle, where seismic waves travel faster in the denser materials of the mantle compared to the less dense crust.
