Question

Which of the following is caused by the interaction of charged particles, magnetic lines of force, and the atmosphere in polar regions? Group of answer choices 1. Van Allen belts 2. dipole 3. aurorae 4. troposphere

Answer 1

Option (3)

Step-by-step explanation:

Aurora refers to those northern and southern light observed in both the poles of earth. At the poles, when sunlight comprised of numerous charged particles are emitted from the sun are incident on the atmosphere of the earth, it reacts with the earth's magnetic field and results in the rapid movement of electrons within the atoms, from a region of lower energy state to a higher state. After sometimes when these electrons are back into the lower-energy state then photons are released in the form of beautiful lights which are known as aurora.

These lights are known as aurora borealis when observed in the north pole, and aurora australis when observed in the south pole.

Thus, the correct answer is option (3).
