Ego ledyanaya poverhnost' ispeshrena svetlymi molodymi kraterami, kotorye pokryvayut
bolee staruyu temnuyu poverhnost',
na kotoroi mnogo kraterov,
kotlovin i hrebtov.
Proishozhdenie izrezannogo borozdami rel'efa ostaetsya
predmetom issledovanii,
naibolee veroyatnaya gipoteza predpolagaet, chto ono svyazano so sdvigami ledyanyh plit.
Predpolagaetsya, chto pod poverhnost'yu
Ganimeda
nahoditsya
okean,
v kotorom bol'she vody, chem na Zemle, i vozmozhna
