Among solid worlds, which type of world is most likely to have significant geological activity?
A) those that are the smallest (and thus easiest to heat)
B) those that have strong magnetic fields
C) those that have a moon (satellite)
D) those that are the largest (and retain heat the best)
E) those that are farthest from the Sun

Question

Quizplus · Accepted Answer

Larger worlds retain heat better due to their smaller surface area-to-volume ratio, which slows the loss of internal heat. This retained heat can drive geological activity for longer periods.
