Question

Which of the following best explains why Jupiter's density is higher than Saturn's?

a.Jupiter has a stronger magnetic field than Saturn.
b.Jupiter is closer to the Sun than Saturn.
c.Jupiter is more massive than Saturn.
d.Jupiter has a higher proportion of hydrogen compounds and rock than Saturn.

Answer 1

Jupiter's density is higher than Saturn's because it is more massive, leading to greater gravitational compression and a denser core.

Step-by-step explanation:

The correct answer to why Jupiter's density is higher than Saturn's is that Jupiter is more massive than Saturn. The immense mass of Jupiter leads to a stronger gravitational compression, which increases the overall density of the planet. Since both planets have cores of heavier elements like rock and metal, the significant difference in mass means that Jupiter's core will experience more gravitational pressure, making it denser than Saturn's core.

While both Jupiter and Saturn have mantles of liquid hydrogen, and atmospheres largely composed of hydrogen and helium, the greater mass of Jupiter results in a denser planet despite both being gas giants. Moreover, the lack of helium precipitation on Jupiter, compared to Saturn, influences their respective densities.
