- ice covered surface with few impact craters
- hot, glowing lava visible in some photos
- heavily cratered terrain adjacent to much younger terrain
- volcanoes currently erupting
- largest moon in the solar system
- surface features provide evidence of a subsurface liquid ocean

Answer 1

Io
- volcanoes currently erupting
- source of ionized gas in the donut-shaped charged particle belt around jupiter
- hot, glowing lava visible in some photos

Europa
- ice covered surface with few impact craters
- surface features provide evidence of a subsurface liquid ocean

Ganymede
- largest moon in the solar system

Callisto
- heavily cratered terrain adjacent to much younger terrain
