Quizplus · Accepted Answer

The chaotic surface and large blocks are consistent with a thin icy crust that has been broken into pieces by tidal forces below which is a subsurface ocean of water.

Scientists believe there is a subsurface ocean beneath the icy crust due to the surface features and measurements taken by spacecraft.
