Final answer:
Greenhouse gases like carbon dioxide (CO₂), methane (CH₄), and ozone (O₃) absorb and re-radiate infrared energy, thus contributing to global warming. Options a, b and d.
Step-by-step explanation:
The greenhouse gases that contribute to global warming include carbon dioxide (CO₂), methane (CH₄), and ozone (O₃). These gases are known for their ability to absorb and re-radiate infrared energy, which is crucial to the greenhouse effect. Nitrogen (N₂) is not considered a significant greenhouse gas because it does not effectively absorb thermal infrared radiation.
Activities such as agricultural production, the burning of fossil fuels, and large-scale deforestation have increased the concentration of greenhouse gases in the atmosphere, intensifying the greenhouse effect and contributing to climate change.
As for the 35th question mentioned, the gas that is not a significant contributor to global warming is oxygen (O₂), while carbon dioxide, methane, and nitric oxide (correctly referred to as nitrous oxide in this context) are known contributors. Options a, b and d.
