The overwhelming abundance of hydrogen in the outer atmospheres of Uranus and Neptune resembles that in Jupiter, Saturn and the Sun. Unlike Jupiter and Saturn, however, Uranus and Neptune cannot consist mostly of the lightest element hydrogen, or they would have a lower mean mass density then observed.
In what ways are Jupiter and Saturn different from Uranus and Neptune?
Jupiter and Saturn are composed primarily of hydrogen and helium (but hydrogen dominates), but Uranus and Neptune consist in large part of compounds of carbon, nitrogen, and oxygen.
How is the atmosphere of Uranus different from that of Saturn?
Uranus’ atmosphere is predominantly made up of hydrogen and helium. Unlike Jupiter and Saturn, these light gases dominate only the outer edges of the planet, but are not a significant contributor to the rocky interior. … Traces of hydrocarbons are also present in the air around Uranus.
Why do Uranus and Neptune have lots of methane clouds and Jupiter and Saturn do not?
Why do Uranus and Neptune have blue methane clouds but Jupiter and Saturn do not? Methane does not condense into ice in the warmer atmospheric temperatures of Jupiter and Saturn. … Different layers represent clouds made of gases that condense at different temperatures.
How are Uranus and Neptune different from Jupiter and Saturn quizlet?
Uranus and Neptune are much smaller and contain smaller proportions of hydrogen and helium. … Jupiter and Saturn have lower densities than Uranus and Neptune since they have higher percentages of hydrogen and helium. Jovian Planet Interiors. All four Jovian planets have approximately the same size cores.
In what ways are Uranus and Neptune similar to and different from Jupiter and Saturn Why are they so different?
Uranus and Neptune are not unlike the cores of Jupiter and Saturn, which similarly contain 10 to 20 Earth masses of melted ice and molten rock. But Uranus and Neptune are almost all core, without the deep envelope of hydrogen and helium that make up most of the mass of Jupiter and Saturn.
How are Jupiter and Uranus different?
Well, Jupiter is the fifth planet away from the sun and Uranus is the seventh planet away from the sun. … On the other hand, Uranus is just the third largest planet in the solar system. Also, Jupiter has 63 moons and Uranus only has 27 moons. Jupiter is also slightly warmer than Uranus.
What is the difference between Saturn and Jupiter?
The first difference is the planets’ densities. Saturn is significantly less dense than Jupiter. … The hydrogen, helium, and a bit of heavier elements in Saturn take up almost the same space as Jupiter, but Saturn’s mass is half of Jupiter’s. The reason is Jupiter’s strong gravity and its compression.
What is the atmosphere of Saturn?
Atmosphere and Weather: One of the four gas giants, Saturn’s atmosphere is much like that of Jupiter’s. Hydrogen makes up nearly all of the atmosphere, with lesser amounts of helium and much lesser quantities of methane and ammonia.
What is Jupiter’s atmosphere?
Atmosphere and Weather: Jupiter’s extremely dense and relatively dry atmosphere is composed of a mixture of hydrogen, helium and much smaller amounts of methane and ammonia. The same mixture of elements which made Jupiter also made the Sun.
How are Saturn and Neptune different?
Saturn and Neptune are gas giants, both largely comprised of hydrogen and helium. … Saturn is the sixth planet from the sun, and Neptune is the eighth.
Does Jupiter and Saturn have methane?
Methane (CH4) is abundant on the giant planets—Jupiter, Saturn, Uranus and Neptune—where it was the product of chemical processing of primordial solar nebula material. On Earth, though, methane is special.
Why dont Saturn and Jupiter have methane clouds?
Since Saturn’s atmosphere is colder than Jupiter’s at any particular altitude, the various cloud layers occur deeper within Saturn’s atmosphere. Methane can condense in the very cold upper troposphere of Uranus and of Neptune, but not in the warmer troposphere of Jupiter or Saturn.
Which planet has bands and zones similar to Jupiter?
The beauty of Saturn, the Lord of the Rings, has fascinated everyone who has ever seen it through even a small telescope. Like Jupiter, Saturn is a gas giant, which means it’s mostly made of gases like hydrogen and helium, and it doesn’t have a solid surface in the way that rocky planets like Earth do.
What is the significance of the colors of Uranus and Neptune?
The blue-green, turquoise color of Uranus and the blue, indigo color of Neptune come from methane in their clouds. Uranus and Neptune have a similar size, mass, and bulk composition and they are both much smaller, less massive, and denser than the other two giant planets, Jupiter and Saturn.
Which gas is responsible for the blue-green or bluish hue of Uranus and Neptune quizlet?
Neptune and Uranus owe their blue-green color to the preponderance of methane gas in their atmospheres. The colors of Jupiter and Saturn, on the other hand, are due to impurities in the ice crystals, which may include sulfur, phosphorus, and organic materials.
