Why are auroras produced only near the northern and southern magnetic poles of a planet?
A) Those are the locations where the atmosphere is thinner, letting particles penetrate.
B) The poles are pointing toward the Sun, so they receive more solar wind particles.
C) The oxygen atoms responsible for auroral emission only exist near the poles.
D) Charged particles are forced to flow along Earth's magnetic field lines, which come out of Earth's poles.
E) Auroras require large amounts of reflective ice or snow in order to be visible.

Question

Quizplus · Accepted Answer

Charged particles from the solar wind are guided by Earth's magnetic field lines, which converge at the magnetic poles, causing auroras to occur predominantly in these regions.
