Earth is the only planet in our solar system to have a plate tectonics system. Something has allowed the interior of the earth to retain sufficient heat for this to work. We are larger than the other rocky planets who no longer exhibit volcanics though the did do so (Venus and Mars) earlier in their histories. Some of the moons of Saturn and Jupiter exhibit similar effects to tectonics but not quite due to the influence of the gas giants.
Some geologists believe the extra heat / energy of our moon creating collision gave us the extra energy to create an ongoing plate tectonic system.
Aren’t Jupiter and Saturn dwarf suns that never ignited, according to some scientists?
