Motions in Neptune's Interior, part 2
Motions in the interior of a gas-giant planet such as Neptune may be very different from the motions within the Earth.
A second idea for the motions in the interior of a gas-giant planet is shown in this picture. Strong heat coming from within a planet can cause this kind of motion to take place.
The drawing shows that underneath the clouds of Neptune, long logs of material may be in motion, rolling in different directions. It is thought that this pattern may be in operation because the tips of the logs may match up with the striped pattern of clouds seen in the atmosphere.
It is not known which of these two kinds of motion, one typical of the earth, and one like this, takes place in the interior of Uranus.
