Which of the following statements best explains why the densities of Uranus and Neptune are higher than that of Saturn, even though Saturn is much more massive?View Available Hint(s)A. They have higher masses.B. They have stronger magnetic fields.C. They are at greater distances from the Sun.D. They have a higher proportion of hydrogen compounds and rock.E. Their interiors are more compressed due to stronger gravity.

Density is the mass per unit volume of a solid or fluid. The higher density of Neptune and Uranus are due to its composition, the composition of Neptune and Uranus are different from that of Jupiter and Saturn. Despite the fact that Jupiter and Saturn have a larger volume, the densities of Neptune and Uranus is higher because they have much larger fractions of high density materials like hydrogen compounds and rocks. And moreso, density depends mostly on composition rather than volume.

Answer:

D. They have a higher proportion of hydrogen compounds and rock

Explanation:

The density of a substance is defined as its mass per unit volume

ρ = [tex]\frac{m}{v}[/tex]

Although Uranus and Neptune are planets of a smaller size than Saturn, they have a higher proportion of hydrogen compounds and rock, and for this reason, their densities are higher than then Saturn's density

The answer is

D. They have a higher proportion of hydrogen compounds and rock
