What largely determines the level of volcanic and tectonic activity on the Galilean moons?
A) whether the crust is light- or dark-colored, which controls how much of the Sun's heat it retains
B) the composition of the crust of each moon
C) the amount of wind and water on each moon's surface
D) proximity to Jupiter and its extreme tidal forces

Question

Quizplus · Accepted Answer

The extreme tidal forces exerted by Jupiter on its Galilean moons are the primary factor influencing the level of volcanic and tectonic activity on these moons. This is because the intense gravitational pull from Jupiter causes significant internal heating and deformation within these moons, leading to geological activity.
