Question

which statement best describes the density of the outer planets? all the outer planets have low density. the outer planets are denser than the inner planets. saturn is dense, but the other outer planets are not. uranus and neptune are dense, but jupiter and saturn are not.

Explanation:

Outer planets include Jupiter, Saturn, Uranus, and Neptune. Jupiter and Saturn are gas giants with very low density (Saturn's density is even lower than water). Uranus and Neptune are ice giants, which have a higher density than Jupiter and Saturn but are still less dense than the rocky inner planets. This means not all outer planets have low density, and the correct distinction is that Uranus and Neptune are denser relative to Jupiter and Saturn.

Answer:

D. Uranus and Neptune are dense, but Jupiter and Saturn are not.
