Three of the moons influence each other in an interesting way. Why are Jupiter’s Galilean moons geologically active? Liquid water from inside Europa causes the ice to move, erasing many of the impact craters. But the debris from Io’s active volcanoes has covered old impact craters. Why are numerous impact craters found on Ganymede and Callisto but not on Io or Europa? All of them have had many impacts over the past billions of years. Why are numerous impact craters found on Ganymede and Callisto but not on Io or Europa? “None of the topography is more than a couple of hundred meters tall,” Philips said. First, spectroscopic measurements have showed that the surface is covered in water ice, and that it is smoother than a cue ball. The Europan surface also offers evidence for liquid-water oceans. What evidence supports the hypothesis that Europa has an active surface and liquid sub surface ocean? Why are few craters seen on Europa? The icy crust of Europa shifts atop an underlying ocean of water, which erases craters from the surface. Why are no craters seen on Io? The volcanoes and geologically active mountains on Io erase craters from the surface. Solar radiation reflected of Jupiter’s surface provides a power source for geological activity. What causes the geological activity seen on Europa and Io?ĭ. The reason for its continued activity is due to tidal heating – a continual flexing and stretching of the Europa caused by the shape of its orbit and gravitational pull from Jupiter, Io, and Ganymede. However, Europa is smaller than our Moon (Table1), yet it is still geologically active. This extreme geologic activity is the result of tidal heating from friction generated within Io’s interior as it is pulled between Jupiter and the other Galilean moons-Europa, Ganymede and Callisto. With over 400 active volcanoes, Io is the most geologically active object in the Solar System. As a result, some of the icy moons contain interiors warm enough to host oceans of liquid water, and in the case of the rocky moon Io, tidal heating melts rock into magma. In a process called tidal heating, gravitational tugs from Jupiter’s moons and the planet itself stretch and squish the moons enough to warm them. What is tidal heating? Which moon has a thick atmosphere made mostly of nitrogen? Which forces cause tidal heating of Jupiter’s moon? Which statement about Jupiter’s moon Io is true? It is the most volcanically active body in our solar system. Which statement about Jupiter’s moon Io is true? These tidal forces generate the heat that drives Io’s intense volcanic activity, according to NASA. The volcanic moon is Jupiter’s third-largest and the innermost Galilean satellite, it finds itself caught in a gravitational tug-of-war between Jupiter and two nearby Jovian moons Europa and Ganymede. What causes the heating of Io that gives rise to volcanic activity? The generation of heat due to friction produced by the strong tidal forces exerted by a very massive parent body on a body moving about it in an elliptical orbit. Io has a similar mass and size as the Moon, but Io is the most geologically active body in the Solar System. Orbital and rotational energy are dissipated as heat in the crust of the moon. Tidal heating of Io (also known as tidal working) occurs through the tidal friction processes between Jupiter and its moon. Why does Io experiences strong internal tidal heating?
