What is the Moho?
What will be an ideal response?
The Moho is defined by a sharp increase in seismic wave velocities that separates the Earth's crust and mantle. P-wave velocities in the crust of around 5–6 km/sec increase to uppermost mantle velocities of about 8 km/sec. Beneath the continental crust, the depth to the Moho ranges from as much as 75 km in young mountain belts to 20 km in areas undergoing extension and crustal thinning. Beneath the oceanic crust, the Moho is at a nearly constant depth of around 7 km below the ocean floor.
