When Io passes between Jupiter and Europa, both moons experience gravitational stress. On Europa this is responsible for three of the features listed below. Which feature does NOT occur as a result of the gravitational flexing of Europa?
A) cracks on the surface
B) heat to keep subsurface water liquid
C) water geysers
D) lava/sulfur volcanoes

Question

Quizplus · Accepted Answer

Lava/sulfur volcanoes are not a feature caused by the gravitational flexing of Europa. This phenomenon is more closely associated with Io, which is the most volcanically active body in the Solar System due to its intense gravitational interaction with Jupiter. Europa's surface features such as cracks, subsurface liquid water, and possible water geysers are influenced by tidal heating from gravitational interactions, but not volcanic activity similar to Io's.
