Question

Io's elliptical orbit is necessary to its tidal heating. This elliptical orbit, in turn, is a result of the orbital resonance among Io, Europa, and Ganymede. This orbital resonance causes Io to have a more elliptical orbit than it would otherwise, because_________

Answer 1

Answer: Io periodically passes Europa and Gynamede In the same

orbital position.

Step-by-step explanation:

Because it takes Io to rotate in 1.7 days, Europa in 3.5 days, and Ganymede in 7.5 days; hence, their period of rotation is equivalent to the ratio of 1:2:4.
