Final answer:
The Van Allen belts are created by Earth's magnetosphere, which traps charged particles from the solar wind.
Step-by-step explanation:
The Van Allen belts are created by Earth's magnetosphere. The magnetosphere is the region of space surrounding the Earth where the Earth's magnetic field is present. It is caused by the movement of molten iron in the Earth's outer core. The magnetosphere traps charged particles from the solar wind, creating the two doughnut-shaped Van Allen belts around the Earth.
