INTERPRETING GRAPHICS
The graph below shows density versus mass for Earth, Uranus, and Neptune. Mass is given
in Earth masses—the mass of Earth is equal to 1 Earth mass. The relative volumes for the
planets are shown by the size of each circle. Use the graph below to answer the questions that
follow.
27. Which planet is denser, Uranus or Neptune? How can you tell?

28. You can see that although Earth has the smallest mass, it has the highest density of the
three planets. How can Earth be the densest of the three when Uranus and Neptune have
so much more mass than Earth does?
