In Greenhouse gases, which option helps you separate two similar atmosphere ideas: Define greenhouse gases as gases that absorb infrared radiation emitted from the Earth's surface?

The correct option is Increased energy retained in the atmosphere. For this comparison 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.

Increased energy retained in the atmosphere is the correct answer for this AQA GCSE Chemistry atmosphere question. Avoid answers that mix greenhouse gases, pollutants, or early-atmosphere changes. 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.
