Why are gases like nitrogen (N₂) and oxygen (O₂) not greenhouse gases, despite being gases that exist in the atmosphere? (1 point)O They occur naturally, so they cannot contribute to global warming.O They are tightly bound, so they cannot vibrate and release radiation.O They are made of only one element, so they do not have the components necessary to be a greenhouse gas.O They exist in such large quantities that Earth is already used to them and is not affected by their activity.
