Aurora-like luminous events are mainly related to which upper region?
Answer and explanation
Correct answer: Ionised region of the thermosphere
Auroras occur when energetic charged particles from the Sun interact with gases in the upper atmosphere, especially the ionised region commonly associated with the ionosphere and thermosphere. This interaction produces visible light. Clouds and rainfall belong mainly to the troposphere, and the ozone layer is not the main source of auroras. Hence, option A is correct.
