multiple - choice question
the moho marks the boundary between the ______ and is due
to rapid speed changes due to rapid changes in _______
crust and mantle, density
inner and outer core, color
core and mantle, density
crust and core, temperature
rewatch

Explanation:

The Mohorovičić discontinuity (Moho) is the boundary between the Earth's crust and mantle. This boundary is identified by a rapid change in seismic wave speed, which is due to a rapid change in density (the mantle is denser than the crust). The other options are incorrect: the inner and outer core boundary is not related to color; the core - mantle boundary is the Gutenberg discontinuity; and the crust - core is not separated by the Moho and temperature is not the relevant property here.

Answer:

crust and mantle, density
