Saturn's magnetosphere contains many fewer charged particles than does Jupiter's magnetosphere. Which one of the following is NOT part of the reason for this difference?

Question

Quizplus · Accepted Answer

The number of charged particles in a magnetosphere is largely determined by the strength of the magnetic field and the presence of sources such as active moons or solar wind. While Saturn's magnetic field is weaker than Jupiter's (choice A), this alone does not explain the significant difference in charged particle content. Saturn's rings do indeed absorb charged particles (choice C), and this is one factor contributing to the lower particle count. Additionally, Jupiter has several geologically active moons which act as sources for charged particles, while Saturn does not (choice D). However, Saturn's slower rotation rate (choice B) does not have a significant effect on the number of charged particles in its magnetosphere.
