검증된 단계별 안내1
Understand the concept of greenhouse gases: Greenhouse gases are those that can absorb and emit infrared radiation, leading to the greenhouse effect, which warms the Earth's atmosphere.
Identify common greenhouse gases: Some well-known greenhouse gases include carbon dioxide (CO2), methane (CH4), and water vapor (H2O). These gases are effective at trapping heat in the atmosphere.
Consider the properties of nitrogen (N2): Nitrogen makes up about 78% of the Earth's atmosphere but is not a greenhouse gas because it does not absorb infrared radiation effectively.
Compare the given options: Methane (CH4), water vapor (H2O), and carbon dioxide (CO2) are all known greenhouse gases, while nitrogen (N2) is not.
Conclude which option is not a greenhouse gas: Based on the properties and roles of these gases, nitrogen (N2) is the one that does not contribute to the greenhouse effect.
