What evidence has been obtained concering the existence of the moho and earths mantle?
The existence of the Mohorovičić discontinuity, or Moho, is evidenced by seismic wave studies, which show a distinct change in wave speeds at depths of about 5 to 70 kilometers, indicating a transition from the Earth's crust to the underlying mantle. Seismic waves travel faster in the denser mantle compared to the less dense crust, confirming the presence of this boundary. Additionally, the analysis of mantle rocks brought to the surface by volcanic activity and studies of meteorite compositions provide further insights into the mantle's characteristics and composition.
