Which gas is primarily responsible for the green color in auroras?
-
Nitrogen
-
Oxygen
-
Helium
-
Carbon dioxide
That's Correct!
It's Wrong!
The correct answer is "oxygen". The green color in auroras is primarily caused by excited oxygen atoms in the Earth's atmosphere. When charged particles from the solar wind collide with these atoms, they release energy in the form of light, resulting in the characteristic green hue that is often observed during this phenomenon.
