Question

Mohorovicic discontinuity is the boundary between ________ and _________.

• A. crust and core
• B. mantle and core
• C. crust and mantle
• D. none of these

Answer 1

The correct option is C crust and mantle

The Mohorovicic Discontinuity, or Moho is the boundary between the crust and the mantle. This boundary is located at approximately 2891 km depth beneath the Earth's surface. The boundary is observed via the discontinuity in seismic wave velocities at that depth. This discontinuity is due to the differences between the acoustic impedances of the solid mantle and the molten outer core.
