Aurora can be considered a direct indication of which process?
Answer and explanation
Correct answer: Interaction of charged solar particles with upper-atmospheric gases
Aurora is produced when charged particles carried by the solar wind are guided by Earth’s magnetic field toward polar upper-atmosphere regions. Collisions with oxygen and nitrogen excite those atoms and molecules; when they return to lower energy states, they emit coloured light. Option A correctly states the process. The other choices describe water-related weather or clouds, which are not the mechanism of auroral displays.
