Surface of Ganymede
The surface of Ganymede is halfway between that of Callisto
and that of Europa
. Portions of the crust are of ancient age, while other portions are relatively new
The little white dots shown in this image are the many imact craters on Ganymede. Portions of Ganymede that are heavily cratered have not been resurfaced, indicating that they are of ancient age.
Besides the craters, the surface of Ganymede is made of grooved terrain, light terrain, and dark terrain.
Because many different kinds of terrain can be found on the surface of Ganymede, some processes of change in the interior must have taken place during Ganymede's history.
