Process of Science: Why is it important to understand the Sun in order to understand the Earth's radiation belts and space weather?
What will be an ideal response?
Solar activity causes the responses in the near-Earth space environment that produce changes in the radiation belts, so an understanding of how the Sun changes is directly relevant to space weather.
