I do not know too much about geology (I do not even know if the study of the surface of foreign planets should be called geology), but the many surface features suggests vasts quantities of fluids running along the surface at one time. No point to that observation, the observation is the point.
Enceladus is close to Saturn and heavily affected by its gravity. The tidal forces push and pull at the ice crust of the tiny moon causing fissures to form. The cracks are a result of the icy crust breaking and reforming, hence the ice plumes near the southern pole.
I believe Jupiter’s moon Europa suffers the same fate.
