What are Saturn's rings primarily made of?

Saturn's rings are primarily composed of ice particles, along with a smaller amount of rocky debris. The dominant presence of ice is a significant factor in the rings' brightness and their overall appearance. Many of these ice particles range in size from tiny grains to larger chunks, which can be several meters across. This composition allows for the reflection of sunlight, making the rings one of the most striking features of the planet.

The presence of rocky debris within the rings adds to their complexity but is far less significant compared to the vast quantity of ice. The combination of these materials contributes to the dynamic nature of the rings, which can undergo changes due to gravitational interactions, collisions between particles, and the influence of Saturn's moons. Overall, the correct answer captures the primary composition of Saturn's rings, emphasizing the importance of both ice and rocky components in their structure.
