Answer: CO 2 , CH 4 , N 2 O, and water vapor.
- A Oxygen (O<sub>2</sub>) and nitrogen (N<sub>2</sub>)
- B CO<sub>2</sub>, CH<sub>4</sub>, N<sub>2</sub>O, and water vapor
- C Carbon dioxide (CO<sub>2</sub>) mainly
- D Oxygen (O<sub>2</sub>) gas mainly
Correct answer: B. CO<sub>2</sub>, CH<sub>4</sub>, N<sub>2</sub>O, and water vapor
Explanation: Greenhouse gases (CO<sub>2</sub>, methane, N<sub>2</sub>O, H<sub>2</sub>O vapor) trap heat in the atmosphere, causing the greenhouse effect.
