Why is aurora mainly seen in the upper atmosphere?
Answer and explanation
Correct answer: Charged solar particles collide with gases in the upper atmosphere
Aurora is produced when charged particles from the solar wind are guided by Earth’s magnetic field toward polar regions and collide with oxygen and nitrogen high in the atmosphere. The excited gases emit coloured light as they return to lower energy states. Therefore option A gives the correct cause. Sea waves, rain, and dense exospheric clouds do not produce auroras.
