The ‘Moho’ (Mohorovičić Discontinuity) is primarily identified by a sudden increase in the velocity of which waves?
The Moho is the boundary between the Earth’s crust and the mantle. It was discovered because P-waves traveling through the deeper mantle arrive at distant stations faster than those traveling through the shallower crust. This indicates that the mantle is made of much denser rock (peridotite) than the crust. ANSWER: (C) P-waves
