Answer to Question 1

ANS: D
Density is the measurement of mass per unit of volume. It is an expression of the relative heaviness of
a substance. Information can be found in the section Earth's Interior Is Layered.

Answer to Question 2

ANS: B
The height of the continental crust is dependent upon the depth and the size of the portion that is in the
asthenosphere. Erosion can have an effect on the isostatic equilibrium because it is connected to mass
and density. Information can be found in the section Earth's Inner Structure Was Gradually Revealed.
