Question

there is volcanic activity on jupiters moon ganymede. callisto. io. europa. this is caused by the interaction of jupiters gravity and the gravity of the other galilean moons. tectonic plates moving toward or away from each other. jupiters strong magnetic field. a liquid water ocean locked under a fractured ice surface.

Explanation:

Jupiter's moon Io is known for its intense volcanic activity. This is due to tidal heating caused by the interaction of Jupiter's gravity and the gravity of the other Galilean moons. Io is squeezed and flexed by these gravitational forces, generating internal heat that drives the volcanic activity.

Answer:

First question: C. Io
Second question: A. the interaction of Jupiter's gravity and the gravity of the other Galilean moons
