Answer:

Seismic waves traveled at varying speeds.

Explanation:

The Moho Discontinuity was discovered by one Croatian seismologist, Andrija Mohorovicic. He realized that the speed of a seismic wave depends on the density of the material the wave is moving through. Mohorovicic interpreted the acceleration of seismic waves observed within the Earth's crust as a change in composition of matter within the Earth.
