Question

BlackTom AI · Accepted Answer

The question asks about the most important greenhouse gases in the Earth's atmosphere.
Option 1: 'nitrogen and methane' While methane is a greenhouse gas and plays a role in warming, nitrogen is a non-greenhouse gas in terms of infrared absorption and does not contribute to the greenhouse effect in the same way as CO2 or H2O. So this pairing overstates methane's impact relative to nitrogen's minimal direct greenhouse effect.
Option 2: 'nitrogen and oxygen' These two gases make up the bulk of the atmosphere but are largely transparent to infrared radiation; they do not trap heat effectively, so this combination is not correct for the most important greenhouse gases.
Option 3: 'ozone and oxygen' Ozone is a greenhouse gas in certain layers and has important photochemical roles, but oxygen itself is not a significant greenhouse gas; overall, this pair does not reflect the primary drivers of the greenhouse effect in the atmosphere.
Option 4: 'carbon dioxide and water vapor' Both carbon dioxide (CO2) and water vapor (H2O) are the principal greenhouse gases responsible for absorbing infrared radiation and contributing to the greenhouse effect; CO2 is a major anthropogenic contributor, and water vapor is a powerful natural greenhouse gas that amplifies warming through feedback mechanisms. This combination best represents the main greenhouse gases in the atmosphere.
