Question

Quizplus · Accepted Answer

Io's volcanic flows are composed primarily of sulfur and its compounds. This is because Io has a high concentration of sulfur in its composition, and the volcanic activity on the moon is driven by the heat generated from tidal interactions with Jupiter. The volcanic eruptions on Io are some of the most active in the solar system, and the sulfur-rich magma and lava create dramatic and colorful features on the moon's surface.
