Question

Quizplus · Accepted Answer

The terrestrial planets, including Earth, are composed mainly of rocky material and therefore have much higher densities than liquid water. The appropriate range in average densities of the terrestrial planets is 4 to 6 grams/cc, with Earth having a density of approximately 5.5 grams/cc. This is due to the fact that the rocky materials making up the interiors of these planets are denser than water. Choice A and D are too low and Choice B is too narrow.
