What might cause a moon to be geologically active while its planet is not?
A) The moon may contain more magnetic material than the planet.
B) The moon's rotation is tidally locked to the planet.
C) Heating of the moon by its planet's heat of formation.
D) The moon orbital distance from the planet and/or other moons may cause tidal stresses that can heat its interior.

Question

Quizplus · Accepted Answer

Tidal stresses from the gravitational pull of the planet and/or other moons can cause the moon's interior to heat up and create geological activity, even if the planet itself is not geologically active. The other choices do not directly relate to the potential for a moon to be geologically active.
