Aurora formation is most related to which combined condition?
Answer and explanation
Correct answer: Charged solar particles and upper atmospheric gases
Option B is correct. During aurora formation, charged particles carried by the solar wind are guided by Earth’s magnetic field toward the polar upper atmosphere. They collide with oxygen and nitrogen atoms or molecules, exciting them; when these particles return to lower energy states, they emit characteristic coloured light. Rain clouds, surface dust, and monsoon moisture do not provide this mechanism.
