Yes, Uranus can continue to generate internal heat through gravitational contraction, albeit at a much slower rate than in its earlier formation. As the planet cools, the gravitational energy from the slow contraction of its mass can be converted into thermal energy. However, this process is not the primary source of heat for Uranus today; much of its internal heat is residual from its formation. Overall, while gravitational contraction may contribute to its internal heat, it plays a limited role compared to other factors.
False
The heat source for Jupiter and Saturn is primarily internal heat left over from their formation, along with some heat generated by the decay of radioactive elements in their cores. Gravitational compression from their massive sizes also contributes to maintaining their internal temperatures.
The extreme heat of the core is primarily caused by the process of radioactive decay of elements such as uranium, thorium, and potassium. This heat, combined with the heat left over from the Earth's formation and gravitational compression, creates the high temperatures found in the Earth's core.
Jupiter and Saturn are hot inside primarily due to the immense pressure and gravitational forces at their cores, which generate heat through processes like gravitational contraction and the slow release of heat from their formation. Additionally, both planets have significant amounts of hydrogen, which can retain heat effectively. This internal heat can create a temperature that is much higher than expected, despite their distance from the Sun. Thus, their internal warmth is a result of their own mass and composition rather than solar heating.
Which internal energy source produces heat by converting gravitational potential energy into thermal energy?
Friction from gravitational forces.

Mainly the heat is caused by radioactive decay, but there will be a small contribution due to gravitational pressure.

The Inner Core is the source of the internal heat of the Earth. This is composed of heat generated by gravitational pressure, and by the heat from nuclear disintegration of radioactive materials. This heat gradually spreads outwards.
