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:

The outer planets (Jupiter, Saturn, Uranus, Neptune) are gas giants. Their composition (mostly gases like hydrogen and helium) results in lower density compared to inner rocky planets. Saturn has the lowest density among all planets (less than water). All outer planets have low - density due to their gaseous nature.

Answer:

All the outer planets have low density.
