B.Greenhouse gases like water vapor and carbon dioxide trap heat in the atmosphere, thereby radiating heat energy back to the surface.


C.Greenhouse gases like water vapor and carbon dioxide trap heat in the atmosphere, thereby radiating heat energy back into space.


D.Greenhouse gases like water vapor and carbon dioxide trap heat in the atmosphere, thereby radiating heat energy back into space.
