Io's volcanic flows are primarily composed of sulfur and its compounds, including sulfur dioxide and sulfuric acid. These materials create a range of colorful volcanic features on Io's surface. Io's volcanic flows are primarily composed of sulfur and its compounds, including sulfur dioxide and sulfuric acid, which give the moon its colorful appearance. Basaltic lava is common on Earth, the Moon, and Mars, but not on Io. Liquid nitrogen is too cold and too volatile to form the flows observed on Io, and carbon dioxide and water vapor are not present in significant quantities on Io.
