A student is making a model of the layers of Earth. She is using materials with different densities to represent the layers. The table shows the materials she has chosen for two layers.
How should the density of the material the student uses for the mantle compare to the density of the materials chosen for the other layers?
A. It should be more dense than foam.
B. It should be more dense than glass.
C. It should be the same density as foam.
D. It should be the same density as glass.
