Answer: Longwave infared radiation
Step-by-step explanation:
Greenhouse gases in the atmosphere, such as water vapor(H2O) and carbon dioxide(CO2), absorb most of the Earth's emitted longwave infrared radiation, which heats the lower atmosphere. Once in the Earth's atmosphere, clouds and the surface absorb the solar energy. The ground heats up and re-emits energy as longwave radiation in the form of infrared rays. Earth emits longwave radiation because Earth is cooler than the sun and has less energy available to give off.
Hope that helps :)
