|
Jupiter
|
largest, most mass, Great Red Spot
|
|
|
Saturn
|
The most prominent feature is its system of rings. Very active atmosphere, with winds roaring at up to 1500 kilometers per hour. Large cyclonic "storms".
|
|
|
Uranus
|
It rotates "on its side." Lies parallel with the plane of its orbit. Has the appearance of rolling. Has a ring system. Has at least nine distant ring belts.
|
|
|
Neptune
|
Has a dynamic atmosphere. The windiest places in the solar system. Has an Earth-size blemish called the Great Dark that is assumed to be a large rotating storm.
|
|
|
Pluto
|
Lies on the fringe of the solar system. 10,000 times too dim to be visible to the unaided eye. Takes it 248 Earth- years to orbit the sun because of its great distance and slow orbital speed. Its orbit is highly eccentric, causing it to occasionally travel inside the orbit of Neptune. in 1978 the moon Chavon was discovered orbiting it.
|
|
|
What is Jupiter's mass
|
2 1/2 times greater than the mass of all of the other planets and moons combined.
|
|
|
Is it true or false that Jupiter's surface is thought to be a giant ocean of liquid water
|
true
|
|
|
Which one of Jupiter's moons, is one of only three volcanically active bodies in the solar system
|
Lo
|
|
|
What are Jupiter's rings made up of?
|
The rings are composed of fine dark particle similar in size to smoke particles. The particles are thought to be fragments blasted by meteorite impacts from the surfaces of Metis and Adrastea two small moons of Jupiter.
|
|
|
What is Saturn's prominent feature
|
ring system
|
|
|
What is the feature of some of Saturn's rings?
|
The rings are densely packed.
|
|
|
What is the feature of Saturn's outer ring
|
They composed of widely dispersed particles.
|
|
|
It is true or false the Saturn has large cyclonic "storms" similar to Jupiter's Great Red Spot
|
true
|
|
|
Which planets have a ring system?
|
all four Jovian planets
|
|
|
What unusual feature does Saturn's moon Titan share with Neptune's moon Triton?
|
They are both the only moons in the solar system known to have substantial atmospheres.
|
|
|
What is unique about Uranus's axis of rotation
|
The axis lies nearly parallel with the plane of its orbit.
|
|
|
Is it true or false the Uranus's rings were discovered when Uranus passed in front of a distant star and blocked its view
|
true
|
|
|
Uranus's moon Miranda has a greater variety of what than any solar system body yet examined
|
landforms
|
|
|
is it true or false that Neptune has winds exceeding 1000 km per hour
|
true
|
|
|
What is the substance that most likely makes up Neptune;s upper cloud layer
|
frozen methane
|
|
|
What does the retrograde motion of Neptune's moon Triton indicate about its origin
|
That Triton formed independently of Neptune and was gradationally captured.
|
|
|
Pluto's orbit is highly what, causing it to sometimes travel inside the orbit of Neptune
|
eccentric
|
|
|
What is Pluto's structure
|
A dirty iceball of frozen gases with lesser amounts of rocky substances. A growing number of astronomers assert that Pluto's small size and locations within a swarm of similar icy objects mean that should be reclassified as a minor planet.
