Io experiences tidal heating primarily because __________. correct answers Io's elliptical orbit causes the tidal force on Io to vary as it orbits Jupiter. As you learned in Part A, 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 __________. correct answers Io periodically passes Europa...

-- Life, orbital resonances, rings and gaps. - ️️Give three examples of current properties of the solar system that a model of its formation need not explain. Why? 11. How did the temperature structure of the solar nebula affect the planetary composition? - ️️-- The distance between a planet and the sun determines the temperatures at which each planet was created. For planets close to the Sun like Mercury and Venus, the temperature was too high for those planets to be formed with light ...
