Quizplus · Accepted Answer

Io is known to be the most volcanically active body in our solar system. It has over 400 active volcanoes and its surface is constantly changing due to volcanic activity.

Answer: B
 While there is no direct evidence of a subsurface ocean on Io, studies suggest that it could have a deep, subsurface ocean of liquid water due to the tidal forces it experiences from Jupiter and other moons.

Answer: C
 Io is not the largest moon in the solar system. That title belongs to Ganymede, which is also a moon of Jupiter.

Answer: D
 Io is not the only moon in the solar system with a thick atmosphere. Titan, a moon of Saturn, also has a thick atmosphere. However, Io does not have a significant atmosphere.
