They're characterized by a central, sharp peak and side areas that appear to be collapsing toward the plains. The higher of these peaks range from 2.3 to 6.1 miles in elevation.⁣⁣ Io is the most volcanically active world in the solar system. You can see this in the upper-left, where extremely large flow fields – areas where lava flows have been deposited – are visible. The most active flow regions are marked by their darker color.⁣⁣ Image description: Io is a deep, rusty red with a whitish cast over it. Yellow lava flows and white deposits mark the top portio...
