Question
Which one of the following statements is TRUE for Greenhouse Gas (GHG) in the atmosphere?
Correct answer
(D) GHG allows the incoming short wavelength solar radiation to pass through to the earth surface, and absorbs the long wavelength radiation coming from the earth surface
Solution
Greenhouse gases (GHGs) like , , and water vapor are relatively transparent to incoming short-wavelength solar radiation, allowing it to reach and warm the Earth's surface. However, they are effective at absorbing long-wavelength (infrared) thermal radiation emitted back from the Earth's surface, trapping heat in the atmosphere.
