Which planet may have helium rain in its interior, and what does this rain do? Saturn, where it generates heat as it falls downward. Models suggest that this helium rain may explain Saturn’s internal heating.

Why do Uranus and Neptune have blue methane clouds but 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.

Which Jovian planet has the most extreme seasonal changes and why group of answer choices?

The Jovian planet that has the most extreme seasonal changes is Uranus. The main cause of extreme seasonal changes is that first Uranus? s axial tilt…

Which of the following best explains why some of the jovian moons have been more geologically active than the Moon or Mercury?

Which of the following best explains why many jovian moons have been more geologically active than the Moon or Mercury? Jovian moons are made mostly of ice that can melt or deform at lower temperatures than can the rock and metal that make up the Moon and Mercury.

Which of the following best explains why we see horizontal stripes in images of Jupiter and Saturn?

Which of the following best why we see horizontal “stripes” in photographs of Jupiter and Saturn? The light stripes are regions of high clouds, and the dark stripes are regions where we can see down to deeper, darker clouds.

Why do astronomers believe Triton may have been a planet that was captured by Neptune quizlet?

Why do astronomers believe Triton may have been a planet that was captured by Neptune? It orbits Neptune in the opposite direction of Neptune’s rotation. Why does Titan have such a nitrogen-rich atmosphere?

Why do astronomers believe Triton may have been a dwarf planet that was captured by Neptune?

Nitrogen. Why do astronomers believe Triton may have been a dwarf planet that was captured by Neptune? It orbits Neptune in the opposite direction of Neptune’s rotation. What do asteroids and comets have in common?

Which of the Jovian planets have rings?

• Jupiter: faint, dusty rings.
• Saturn: bright, spectacular rings.
• Uranus: dark, thin rings.
• Neptune: dark, thin rings & ring arcs.

How do the interiors of the other Jovian planets compare to that of Jupiter?

How do the interiors of the other Jovian planets compare to that of Jupiter? Saturn is the most similar to Jupiter; the layers only differ because of its lower mass and weaker gravity. The less mass makes the outer lying layers’ weight less on Saturn. … Jupiter is still slowly contracting.

Why is Jupiter denser than Saturn Why is Jupiter denser than Saturn?

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.

Which jovian planet has the most extreme seasonal changes and why quizlet?

Which jovian planet should have the most extreme seasonal changes? Uranus. Its large axis tilt gives it seasons that each last about ¼ of its 84-year orbit.

Do Jovian planets have seasons?

Which planet has least extreme seasonal variations?

F at night to 800 degrees F during the day for parts of the surface. And yet near Mercury’s poles there is almost no change in temperature, because, in spite of its very long duration between sunrises (176 Earth days), the tilt of its axis is zero, meaning that there are no seasonal variations on Mercury.

What types of clouds are visible on Uranus and Neptune?

Methane gas absorbs red light, and methane clouds reflect blue light, giving Uranus and Neptune their distinctive blue colors.

On which planet does helium rain fall?

Using one of the world’s most powerful lasers, physicists have found experimental evidence for Saturn’s helium “rain,” a phenomenon in which a mixture of liquid hydrogen and helium separates like oil and water, sending droplets of helium deep in the planet’s atmosphere.

What causes the rings of Saturn?

Rings. Saturn’s rings are thought to be pieces of comets, asteroids, or shattered moons that broke up before they reached the planet, torn apart by Saturn’s powerful gravity. They are made of billions of small chunks of ice and rock coated with other materials such as dust.

What planet does Triton orbit?

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. Scientists think Triton is a Kuiper Belt Object captured by Neptune’s gravity millions of years ago.

How big is Triton vs Neptune?

Also, with a diameter 5.5% that of Neptune, it is the largest moon of a gas giant relative to its planet in terms of diameter, although Titan is bigger relative to Saturn in terms of mass.

What planet is Uranus?

Uranus is the seventh planet from the Sun, and has the third-largest diameter in our solar system. It was the first planet found with the aid of a telescope, Uranus was discovered in 1781 by astronomer William Herschel, although he originally thought it was either a comet or a star.

Why do astronomers believe Triton may have been a planet?

Why do astronomers believe Triton may have been a planet that was captured by Neptune? It orbits Neptune in the opposite direction of Neptune’s rotation. … Any particle in the ring with an orbital tilt would collide with other ring particles, flattening its orbit.

How do astronomers think Jupiter generates its interior heat?

How do astronomers think Jupiter generates its internal heat? … Jupiter’s greater mass compresses it more, thus increasing its density.

Is the planet Jupiter magnetic?

Jupiter is surrounded by an enormous magnetic field called the magnetosphere, which has a million times the volume of Earth’s magnetosphere. Charged particles are trapped in the magnetosphere and form intense radiation belts.

How do the Jovian planets differ in their interiors?

How do the jovian planet interiors differ? All have cores of about the same mass, but differ in the amount of surrounding hydrogen and helium. … Accretion took longer further from the Sun, so the more distant planets formed their cores later and captured less gas from the solar nebula than the closer jovian planets.

What are the interiors of Jovian planets like?

Interiors. The cores of all four jovian planets are made of some combination of rock, metal and hydrogen compounds. Jupiter and Saturn have similar interiors, with layers extending outward of metallic hydrogen, liquid hydrogen, gaseous hydrogen, and topped with a layer of visible clouds.

Which of the Jovian planets has no internal energy source?

While we are certain Saturn is not still contracting, it seems clear that Neptune is still contracting. Uranus is the only jovian planet not emitting excess internal energy.

Why do only gas planets have rings?

Some particles of gas and dust that the planets are made of were too far away from the core of the planet and could not be squashed together by gravity. They remained behind to form the ring system. … The other thing that all rings systems share is that they are all made of small particles of ice and rock.

Why is Jupiter a Jovian planet?

Definition: The term Jovian is derived from Jupiter, the largest of the Outer Planets and the first to be observed using a telescope – by Galileo Galilei in 1610. … A planet designated as Jovian is hence a gas giant, composed primarily of hydrogen and helium gas with varying degrees of heavier elements.

Does Uranus have rings?

Uranus has two sets of rings. The inner system of nine rings consists mostly of narrow, dark grey rings. There are two outer rings: the innermost one is reddish like dusty rings elsewhere in the solar system, and the outer ring is blue like Saturn’s E ring.

Is Neptune denser than Saturn?

Uranus and Neptune are denser than Saturn because they have less H/He, proportionately. But that explanation doesn’t work for Jupiter…. Adding mass to a jovian planet compresses the underlying gas layers. Jupiter is denser than Saturn because it 3 times more massive.

Why Saturn is less dense than Jupiter?

The density of Saturn and Jupiter 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.

Why is Jupiter so much heavier than Saturn?

Jupiters mass is greater than Saturns. Therefore, its gravity is higher and a higher surface gravity compresses the atmosphere to 75 km in thickness. On Saturn, the low mass means less surface gravity and the atmosphere is thicker at 300 km from top to bottom.
