Motions in Saturn's Interior
Motions in the interior of a planet help carry heat from the inside to the outside of the planet.
The drawing shows a kind of movement that is usual in the atmosphere as well as the inside of a planet. Material moves the way water does in a pot that is boiling. In the drawing, there are three different red sheets of activity where the air is turning over.
In the interior of Saturn, the liquid layers are warm enough to move this way. Motions like this in the liquid metallic hydrogen layer inside Saturn cause the big magnetosphere of Saturn.
