Verified step by step guidance

Understand the concept of greenhouse gases: Greenhouse gases are compounds in the atmosphere that trap heat, contributing to the greenhouse effect. Common examples include carbon dioxide (CO2), methane (CH4), and water vapor (H2O).

Identify the properties of each gas listed: Methane (CH4), carbon dioxide (CO2), and water vapor (H2O) are known to absorb infrared radiation and contribute to the greenhouse effect.

Consider the role of nitrogen (N2) in the atmosphere: Nitrogen makes up a significant portion of Earth's atmosphere but does not absorb infrared radiation effectively, thus not contributing to the greenhouse effect.

Compare the gases: Methane (CH4), carbon dioxide (CO2), and water vapor (H2O) are greenhouse gases, while nitrogen (N2) is not.

Conclude which gas is not a greenhouse gas: Based on the properties and roles of these gases, nitrogen (N2) does not contribute to the greenhouse effect and is not considered a greenhouse gas.
