Read the wording for your board, then hide it and explain Absorption and re-emission of infrared radiation in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Gases that absorb outgoing infrared radiation emitted by the warmed Earth gain vibrational energy and re-emit radiation in all directions, so some returns towards the surface and the atmosphere retains more energy.
