An Overview of Neptune's Interior
The Giant planets do not have the same kind of layers inside that the Earth-like planets do. Their evolution was quite different than that of the Earth-like planets, and they have much more gas and ice inside.
Neptune's interior make-up is primarily methane ice, just as Uranus' is.
Motions in the interior of Neptune help form the magnetosphere of Neptune. Heat generated within Neptune helps form the unusual winds of the atmosphere.
