The Giant planets do not have the same kind of structure inside that the terrestrial planets do. Their evolution was quite different than that of the terrestrial planets, and they have much more gas and ice inside.

Uranus's interior composition is primarily that of methane ice.

Motions in the interior of Uranus contribute to the formation of the magnetosphere of Uranus. Heat generated within Uranus contributes to the unusual motions of the atmosphere.

The Giant planets do not have the same layered structure that the earthlike planets do. Their evolution was quite different than that of the earthlike planets, and they have much more gas and ice inside.

Uranus's interior is primarily made of methane ice.

Motions in the interior of Uranus help form the magnetosphere of Uranus. Heat generated within Uranus helps form the unusual winds of the atmosphere.

The Giant planets do not have the same kind of layers inside that the earth-like planets do. The history of the giant planets was so different that they formed with much more gas on the inside.

Uranus is made of ice.

Motions inside Uranus help form the magnetosphere of Uranus. Heat from within Uranus helps to make unusual winds in the atmosphere.
