Io, one of the major moons of Jupiter, is undergoing extensive volcanic activity associated with interior heating that is caused by
A) deposition of energy by particles from within Jupiter's Van Allen belts.
B) original heat caused by gravitational condensation at the moon's formation.
C) tidal distortion and internal friction because of flexing.
D) solar radiation and heat falling on the surface.

Question

Quizplus · Accepted Answer
