D
Nitrogen (N2)
Verified step by step guidance
1
Understand the concept of a greenhouse gas: Greenhouse gases are those that can absorb and emit infrared radiation, leading to the greenhouse effect, which warms the Earth's atmosphere.
Identify the common greenhouse gases: Methane (CH4), Carbon dioxide (CO2), and Water vapor (H2O) are well-known greenhouse gases because they have the ability to trap heat in the atmosphere.
Consider the properties of Nitrogen (N2): Nitrogen makes up a large portion of the Earth's atmosphere but does not have the ability to absorb and emit infrared radiation effectively, thus it is not considered a greenhouse gas.
Compare the gases: Methane, Carbon dioxide, and Water vapor all contribute to the greenhouse effect, while Nitrogen does not.
Conclude which gas is not a greenhouse gas: Based on the properties and effects of these gases, Nitrogen (N2) is not considered a greenhouse gas.
