question 34
planetary rings
have looked exactly the same since they formed along with their parent planet.
are only found around saturn
are most likely continually supplied by impacts into small moons
are all completely solid throughout, just like a dvd

Explanation:

Planetary rings are not static. They are thought to be continuously replenished by impacts on small moons that break them apart and add material to the rings. Planetary rings are not exclusive to Saturn (Jupiter, Uranus, and Neptune also have them), they have changed over time since their formation, and they are not solid but composed of particles.

Answer:

C. are most likely continually supplied by impacts into small moons
