Question

which statement describes how the van allen belts are formed?
when low - energy particles from the sun bounce off earths magnetic field
when high - energy particles from the sun bounce off earths magnetic field
when low - energy particles from the sun are trapped by earths magnetic field
when high - energy particles from the sun are trapped by earths magnetic field

Explanation:

The Van Allen belts are regions of charged particles trapped by Earth's magnetic field. These particles are high-energy (not low-energy) emissions from the Sun, and they are trapped (not bounced off) by the magnetic field, forming the radiation belts.

Answer:

when high-energy particles from the Sun are trapped by Earth's magnetic field
