- In the above image, the dark orange lines crisscrossing Europa’s
surface are called lineae, and may result from fracturing of the surface crust of Europa from tidal flexing, a force related to the gravity exerted on Europa by Jupiter.
- Europa is strongly evidenced as having subsurface oceans of liquid water, with tidal flexing believed to provide the heat that keeps its oceans from freezing.
- Possible hydrothermal vents in the subsurface oceans of Europa (which could be caused by tidal flexing) could hypothetically provide a habitat for life, just as life clusters around hydrothermal vents in the oceans of Earth.
