What two competing processes define the geological state of a moon, according to the final summary?

Answer

The rate at which internal heat is generated versus the rate at which that heat escapes to space.

The geological state is described as a dynamic balance between the rate of internal heat generation (usually tidal flexing) and the rate at which that heat escapes to space.
