Aurora is mainly associated with which upper atmospheric layer?
Answer and explanation
Correct answer: Thermosphere
The governing concept is the interaction between solar particles and gases in the upper atmosphere. Auroras occur mainly in the ionospheric region, which overlaps the upper mesosphere and especially the thermosphere; in school-level layer questions, the thermosphere is the expected answer. Thus option A is correct. The troposphere contains ordinary weather, the stratosphere contains ozone, and the mesosphere is not the principal textbook association for auroras.
