9. The ring system is wide, in diameter about equal to the distance between the ________ and

the ________.

10. Shadows of features at “equinox” showed that the rings are not completely flat, they are

__________ dimensional.

11. Saturn’s surface looks rather calm and bland when in fact it is actually roiling and seething.

The apparently peaceful appearance is due to a haze of high level ________________ in the

atmosphere.

at close to _____ miles per hour, near the speed of sound in the planet’s atmosphere, and

faster than the winds on Jupiter. __________ as much heat comes out of Saturn’s interior

than it receives from the Sun which leads to its dynamic atmosphere.

13. From summer to winter seasons on Saturn, the rings alternately block ___________ on the

18. Cassini sampled the geyser plumes and found they contained methane, nitrogen, ammonia,

and organic molecules, which collectively could be called an organic ____________ soup.

20. The Huygens probe landed on the surface of icy cold Titan in a region with cobbled stones, a

stream _____ where liquid once flowed, liquid methane.
