What is one possible reasons Jupiter and Saturn radiate more energy than they receive from the Sun quizlet?
it has erased craters nearly as fast as they have formed. Why do Jupiter and Saturn radiate more energy than they receive from the sun? The planets are still radiating heat from when they first formed.
What is the most likely reason that Jupiter radiates more energy than it receives from the Sun?
Jupiter radiates 70 percent more energy than it receives from the Sun, mostly because it is still contracting under its own gravity. Uranus and Neptune are less massive than Jupiter and Saturn, probably because they formed earlier than Jupiter or Saturn.
What is the largest contributor to Saturn’s excess energy?
Saturn's excess heat is generated by the precipitation of helium into its metallic hydrogen core. The heavier helium separates from the lighter hydrogen and drops toward the center, somewhat like the heavier ingredients of a salad dressing that hasn't been shaken for awhile.
How is Saturn different from Jupiter?
Saturn and Jupiter have different material organization. Saturn has a big rocky core at the center. In both planets, hydrogen changes from a gas to liquid metal, but in Saturn, it happens much deeper. Saturn is less dense, so the pressure required for liquid metal is at lower depths.
Where does the energy for motion in the atmospheres of Jupiter and Saturn come from?
What are the energy sources for the motions in the atmospheres of Jupiter, Saturn, and Earth? All three atmospheres receive energy from sunlight. In addition, the atmospheres of Jupiter and Saturn receive energy from the internal heat of the planet.
How does this difference affect the magnetic fields of Jupiter and Saturn?
Jupiter has a larger metallic hydrogen core than Saturn, and the larger this region is the stronger a magnetic field can be. Because of the two planets' similar rotation periods, the difference in the magnetic fields must come from the differential core sizes.
Why does Saturn radiate more energy?
Saturn Is Smaller and Brighter Scientists believe this extra energy results from a phenomenon called helium rain. Saturn's more rapid cooling allowed helium droplets to form in its atmosphere, and because they are heavier than hydrogen, they fall toward the center of the planet.
Why does Jupiter radiate more energy?
The jovian planets get their heat from the Sun and from their interiors. Jupiter creates a lot of internal heat and releases this heat by emitting thermal radiation. In fact, Jupiter creates so much internal heat that it emits almost twice as much energy as it receives from the Sun.
Why does Saturn generate more internal energy per kilogram of material than Jupiter?
Saturn has an internal energy source about half as large as that of Jupiter, which means (since its mass is only about one quarter as great) that it is producing twice as much energy per kilogram of material as does Jupiter.
Why does Saturn emit more heat than it receives from the Sun in the form of sunlight?
Why does Saturn emit more heat than it receives from the Sun in the form of sunlight? Gravitational contraction and the settling of helium droplets. – The settling of helium droplets is essentially ongoing differentiation through gravitational contraction, and is the source of Saturn's internal heat.
Why does Saturn have a much cooler interior than Jupiter?
But even with this internal heat, Saturn is colder than Jupiter because it's farther away from the Sun.
What is the source of Jupiter’s excess energy?
What is the source of Jupiter's excess energy? What do our magnetic field and Jupiter's share? Jupiter's magnetic field is much stronger than Earth's, and has a magnetic tail that extends beyond the orbit of Saturn. Like Earth, Jupiter's internal energy is generated chiefly by radioactive decay.
What is the main source of energy on Saturn?
Scientists accept that Saturn draws its extra energy from two sources: (1) heat left over from the planet's formation approximately 4.5 billion years ago, still radiating out into space, and (2) the "raining out" of atmospheric helium.
Why does Saturn have a weaker magnetic field than Jupiter?
This region, in which hydrogen exists in a fluid metallic state around a central rocky core, comprises the inner half of the planet. Compared with Jupiter, less of Saturn's mass and volume consists of this conducting metallic fluid, which may partly explain why Saturn's magnetic field is much weaker.
Why does Saturn have such a strong magnetic field?
Saturn's magnetic field is created as material cycles deep within the planet's fluid interior. Outside Saturn's magnetosphere, a million-mile-per-hour flow of electrically charged particles (electrons and ions) from the sun, called the solar wind, spreads out through the solar system.
What source of energy allows Jupiter and Saturn to radiate more heat than they receive from the Sun?
Internal Energy Internal Energy Jupiter and Saturn radiate more energy at Infrared wavelengths than they receive from the Sun. Energy Source: They are slowly contracting under their own weight. Slow gravitational contraction releases gravitational energy, heating the deep interior.
Does Saturn emit more energy than it receives?
Saturn's Radiation Output: As with Jupiter, Saturn radiates more energy than it absorbs from the Sun. In fact, it emits 2.3 times more energy than it receives.
Does Saturn emit radiation?
Saturn is the source of rather strong low frequency radio emissions called Saturn kilometric radiation (SKR). The frequency of SKR lies in the range 10–1300 kHz (wavelength of a few kilometers) with the maximum around 400 kHz.
In which way does Saturn differ from Jupiter quizlet?
In which way does Saturn differ from Jupiter? Saturn has a smaller zone of liquid metallic hydrogen.
Is Saturn’s magnetic field stronger or weaker than Jupiter’s why is it stronger or weaker?
This region, in which hydrogen exists in a fluid metallic state around a central rocky core, comprises the inner half of the planet. Compared with Jupiter, less of Saturn's mass and volume consists of this conducting metallic fluid, which may partly explain why Saturn's magnetic field is much weaker.
Does Saturn radiate heat?
The interior may reach temperatures of up to 21,000 F (11,700 C). Because the distance to Saturn from the sun averages 886 million miles (1.4 billion kilometers), most of the planet's heat comes from its core. Saturn radiates more than twice as much heat into space as it receives from the sun.
How does the composition of Saturn’s atmosphere compare to that of Jupiter which is the same as that of the Sun?
How does the composition of Saturn's atmosphere compare to that of Jupiter, which is the same as that of the Sun? Saturn's atmosphere contains less helium than does that of either Jupiter or the Sun.
Why is Saturn more oblate than Jupiter?
Even though Saturn rotates slightly slower than Jupiter, it is more oblate because its rotational acceleration cancels a larger fraction of the planet's gravity at the equator.
How does Saturn’s atmosphere differ in structure from that of Jupiter’s and why?
The total thickness of the three cloud layers in Saturn's atmosphere is roughly 200 km, compared with about 80 km on Jupiter, and each layer is itself somewhat thicker than its counterpart on Jupiter. The reason for this difference is Saturn's weaker gravity.
Why is Jupiter’s atmosphere more dynamic than Saturn?
Jupiter gets, on average, about 3.4 times the solar radiation per square meter than Saturn gets. To add to that, it might have more extensive atmospheric mixing going on than Saturn and more organic compounds in its upper atmosphere, which, combined with UV rays, could well play a role in Jupiter's darker lines too.
Why is Saturn the most oblate planet?
Even though Saturn rotates slightly slower than Jupiter, it is more oblate because its rotational acceleration cancels a larger fraction of the planet's gravity at the equator.
Which planet radiates more energy than it receives from the Sun?
Saturn's Radiation Output: As with Jupiter, Saturn radiates more energy than it absorbs from the Sun. In fact, it emits 2.3 times more energy than it receives.
Why is Saturn less dense than Jupiter?
Adding mass to a jovian planet compresses the underlying gas layers. Jupiter is denser than Saturn because it 3 times more massive. Gravity makes it denser.
Why does Saturn have less helium than Jupiter?
Saturn has a smaller metallic hydrogen mantle because its lower overall mass means lower internal pressures. Saturn has less surface Helium than Jupiter (~1/4), probably due to "rainout" in the deep interior.
Why is Jupiter so much more dense than Saturn?
Adding mass to a jovian planet compresses the underlying gas layers. Jupiter is denser than Saturn because it 3 times more massive. Gravity makes it denser. Jovian planets are not quite spherical because of their rapid rotation.
