Discovered by AndrijaMohorovicic in 1909. A Croatian Seismologist.
He discovered that… • The velocity of a seismic wave is related to the density of the material it is traveling through • Seismic waves travel faster through material with a higher density and slower through material with a lower density • MOHO has an average depth of 8 Km beneath the ocean basins and 32 Km beneath the continental surfaces
Discontinuity means… • Asurface where seismic waves change velocity. • Who remembers what velocity is? • What are seismic waves?
