The Mohorovicic discontinuity is based on the discovery that seismograph stations located about 150 km from an earthquake received earthquake waves sooner than those nearer the focus. Mohorovicic reasoned that below a depth of 30 km, there must be a zone having physical properties that permit earthquake waves to travel faster. The Mohorovicic discontinuity is the boundary separating these two layers of the Earth:

Answer:

Yes, Moho discontinuity marks the gap or zone of unevenness in the deep layer of earth crust.

Explanation:

  • Mohorovičić Discontinuity is usually found between the two layers of the earth's crust namely Upper mantle and a lower crust that causes the waves to rise and create tremors and earthquakes at shallow depths.
  • Thus it separates bothe the continental and oceanic crust. moho lies within the entire zone of the lithosphere, only beneath the mid-oceanic ridges and this discontinuity starts from 5 to 10 kilometer below the oceanic floor with an average of 35 kilometers.
  • Immediately above this zone the P-waves due to the refracture nature of the moho which is characterized to 500 m thickness Most of the P and S waves get deflected through the solid inner core and where they don't form a shadow zone.
