Question

Quizplus · Accepted Answer

Io, one of Jupiter's moons, is known for its extreme volcanic activity, which is the most intense in the Solar System. This activity is due to tidal heating from its interaction with Jupiter and other Galilean moons, leading to a surface covered in sulfur and sulfur dioxide, giving it a colorful and dynamic appearance, rather than being dominated by craters or ice.
