How do the densities of the jovian and terrestrial planets compare?
A)Made from the same solar nebula, they are all similar.
B)More massive jovians all have high densities, compared to the tiny terrestrials.
C)All terrestrials are denser than any of the jovians.
D)The closer a planet lies to the Sun, the less its density.
E)No real pattern here; densities vary greatly and are very individual to each world.

Question

Terrestrial planets are denser than the jovian planets because the terrestrial planets are made mostly of rock and metal, which are more dense materials. In contrast, the jovian planets are primarily composed of hydrogen, helium, and other light elements, which have lower densities. Terrestrial planets are composed primarily of rock and metal, giving them a higher density than the gas giants. Jovian planets are mostly made up of lighter gases and ice, resulting in a lower overall density. Therefore, all terrestrials are denser than any of the jovians.
