InterpretationWhy are Uranus and Neptune distinguished from Jupiter and Saturn as "ice giants"?
Need a small nudge?

The term ice giant refers mainly to bulk composition, not a visible frozen shell.

ConnectionAstronomers compare two giant planets. Planet X is dominated by hydrogen and helium. Planet Y is also a giant planet but has a much larger proportion of water-, ammonia-, and methane-rich material in its interior. Which comparison best fits the two planets?
Need a small nudge?

Classify both planets, not just one: first the hydrogen-helium giant, then the volatile-rich giant.
