Quick Summary

A seismic discontinuity is a boundary within the Earth where seismic waves change velocity. The most well-known is the Mohorovičić discontinuity, or Moho, which marks the boundary between the Earth's crust and mantle. This discontinuity was discovered by geophysicist Andrija Mohorovičić. Seismic waves, generated by earthquakes or artificial sources, travel through the Earth's layers. By analyzing how these waves speed up or slow down, scientists can map the Earth's internal structure, including these discontinuities. This field of study is known as seismology, a key part of geophysics.123456
