The Moho discontinuity mainly represents the boundary between which two parts?

Answer and explanation

Correct answer: Crust and mantle

The correct answer is A: the Moho discontinuity is the boundary between the crust and the mantle. Earth has layers with different compositions and physical properties. Seismic waves travel at different speeds when they enter a new material, so a marked change in wave velocity helps scientists identify the Moho. Option A is correct because the Moho separates the thin outer crust from the denser mantle below it. Option B is wrong because the boundary between the outer and inner core is a different internal boundary, not the Moho. Option C is wrong because lithosphere and hydrosphere are not the two layers separated by the Moho; the hydrosphere means Earth’s water. Option D is wrong because the troposphere and stratosphere are atmospheric layers. Exam cue: Moho means crust–mantle boundary.
