Question

Which is not a green house gas?
1-Carbon dio oxide
2-oxygen
3-methane
4-ozone

Answer 1

Answer:

2) oxygen

Explanation:

Oxygen and nitrogen are not greenhouse gases, because they are transparent to infrared light. These molecules are invisible because when you stretch one, it doesn't change the electric field. These are symmetric molecules, made of two identical atoms whose electric fields just cancel each other out.
