The Structure of Saturn's Interior
There is no surface to the giant planets, only a gradual transition from the atmosphere, as depicted in this drawing. The hydrogen and helium of which Saturn is mostly composed change to liquid form under the high pressure conditions found in the interior, but the change is very gradual. Therefore the giant planets do not have strict layers, as the terrestrial planets do.
The liquid portions of Saturn form by far the largest sections of the planet, although the liquid layer is not composed of water. The first liquid layer inside Saturn, immediately under the atmosphere, is the liquid hydrogen layer. Under the liquid hydrogen layer is a liquid metallic hydrogen layer.
At the far interior is the core of Saturn.
