What does tidal heating cause?
The more the tidal force changes, the more the moon stretches, and the more it heats. This heat causes activity like volcanoes and geysers and can keep water liquid to form oceans.
Why is tidal heating important?
Tidal heating is responsible for the geologic activity of the most volcanically active body in the Solar System: Io, a moon of Jupiter. The same mechanism has provided the energy to melt the lower layers of the ice surrounding the rocky mantle of Jupiter’s next-closest large moon, Europa.
Is responsible for the tremendous volcanic activity on Io?
With over 400 active volcanoes, Io is the most geologically active object in the Solar System. 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.
What produces meteor showers quizlet?
Meteor showers are caused by the Earth passing through the orbit of a comet. Swarms of dust particles left behind by the passage of the comet are swept up by the Earth. If the meteoroid survives its passage through the Earth’s atmosphere and strikes the ground, it is called a meteorite.
Which Galilean moon of Jupiter is volcanically active?
Io
Why is IO more volcanically active than our moon quizlet?
Why is Io more volcanically active than our moon? Io has a different internal heat source. 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.

What did the photographs from the Huygens probe reveal?
What did the photographs from the Huygens probe reveal as it landed on Titan? Titan’s surface may contain lakes of liquid methane.
What is unusual about Neptune’s moon Triton?
Triton is the largest of Neptune’s 13 moons. It is unusual because it is the only large moon in our solar system that orbits in the opposite direction of its planet’s rotation―a retrograde orbit. Like our own moon, Triton is locked in synchronous rotation with Neptune―one side faces the planet at all times.
