An Overview of Saturn's Interior
The Giant planets do not have the same layered structure that the terrestrial planets do. Their evolution was quite different than that of the terrestrial planets, and they have less solid material inside.
Saturn's interior composition is primarily that of simple molecules such as hydrogen and helium, which are liquids under the high pressure environments found in the interiors of the outer planets, and not solids.
Motions in the interior of Saturn contribute in a very special way to the development of the powerful and extensive magnetosphere of Saturn. Heat generated within Saturn contributes to the unusual motions of the atmosphere.
