Which Jovian planets have rings?
All Jovian planets have rings:
- Jupiter: faint, dusty rings.
- Saturn: bright, spectacular rings.
- Uranus: dark, thin rings.
- Neptune: dark, thin rings & ring arcs.
How does Jupiter generates its internal heat?
Internal Heat 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 is Jupiter denser than Saturn group of answer choices?
Why is Jupiter denser than Saturn? The extra mass of Jupiter compresses its interior to a greater extent than that of Saturn. Jupiter’s greater mass compresses it more, thus increasing its density.
Which of the following best describes the internal layering of Jupiter from the center outward?

| Which of the following best describes the internal layering of Jupiter, from the center outward? | Core of rock, metal, and hydrogen compounds; thick layer of metallic hydrogen; layer of liquid hydrogen; layer of gaseous hydrogen; cloud layer |
What gives Jovian planets distinctive colors?
The presence of this methane is what gives Uranus and Neptune their hazy blue color, where Jupiter is orange-white in appearance due to the intermingling of hydrogen (which gives off a red appearance), while the upwelling of phosphorus, sulfur, and hydrocarbons yield spotted patches areas and ammonia crystals create …
What is the major component of Io’s volcanic flows?
Although most of the lava on Io is made of basalt, a few lava flows consisting of sulfur and sulfur dioxide have been seen. In addition, eruption temperatures as high as 1,600 K (1,300 °C; 2,400 °F) were detected, which can be explained by the eruption of high-temperature ultramafic silicate lavas.
What is the Cassini Division in Saturn’s rings quizlet?
What is the Cassini division of Saturn’s rings? composed of a large number of individual particles that orbit their planet in accord with Kepler’s third law. known to exist for all of the jovian planets.
Why are Saturns rings so thin?
Why are Saturn’s rings so thin? It has to do with the ring particles colliding with each other. Ring particles that are high above or below the rings are in a highly “inclined” (tilted) orbit, and have more energy than ring particles that are closer to the ring plane.
Which of the Jovian planets have rings quizlet?
The most likely source is impacts with jovian moons. Jovian planets all have rings because they possess many small moons close in. Impacts on these moons are random. Saturn’s incredible rings may be an “accident” of our time.
What is the Cassini Division in Saturn’s rings?
In 1675, Giovanni Domenico Cassini determined that Saturn’s ring was composed of multiple smaller rings with gaps between them; the largest of these gaps was later named the Cassini Division. This division is a 4,800-km-wide region between the A ring and B Ring.
What keeps Saturn’s rings in orbit?
Answer: Saturn’s rings are made up of millions of pieces of rock and dust. The gravity of Saturn holds it all in place but there are some moons that go around Saturn (just like our Moon), called shepherd moons that help to keep the rings in place.
