In Greenhouse gases, which option helps you identify where the gas or pollutant comes from: Define greenhouse gases as gases that absorb infrared radiation emitted from the Earth's surface?

The correct option is . For this source question, that option is correct because it matches Define greenhouse gases as gases that absorb infrared radiation emitted from the Earth's surface in Greenhouse gases.

is the correct answer for this AQA GCSE Chemistry atmosphere question. Look for the source named in the specification, not a general environmental statement. The learning objective is: Define greenhouse gases as gases that absorb infrared radiation emitted from the Earth's surface. In Carbon dioxide and methane as greenhouse gases, this means the explanation must use the subtopic Greenhouse gases and avoid drifting into a different gas, pollutant, climate, or early-atmosphere idea.
