The transfer of energy from radiation to matter when the radiation interacts with it.
Revise: The greenhouse effectAbsorption transfers energy from the radiation to the matter, so the matter gains energy and may become warmer.
Describe a sequence: incoming short-wave radiation → absorption by the Earth’s surface → emission of long-wave infrared radiation → absorption and re-emission by greenhouse gases.
Describe the process as a sequence: incoming solar radiation → absorption by the surface → infrared emission → absorption and emission by greenhouse gases.
