Question 4 • AZ-Earth and Space Science A (SC301)

How are Van Allen belts formed?

Answer
A
High-energy particles from the Sun get trapped in Earth’s magnetic field.
B
Metals in Earth’s core sink and rise, producing a circular movement of the metals.
C
Particles in solar wind travel along lines of Earth’s magnetic field and collide with gas atoms.
D
Material from the surface of the Sun erupts and forms a loop due to the Sun’s magnetic field.

Explanation

The Van Allen belts form when energetic charged particles, mainly from the solar wind, become trapped by Earth’s magnetic field. The field holds these particles in regions around Earth, forming radiation belts. Choice A, “High-energy particles from the Sun get trapped in Earth’s magnetic field,” describes this process.
