The greenhouse effect plays a major role in the climate of a planet. Visit the Greenhouse Effect AstroTour, and use what you learn there to choose all the statements below that are correct. Note that 273 K = 0°C = 32°F.  Choose one or more: A.The Earth has reached thermal equilibrium, emitting the same amount of energy into space as it absorbs from the Sun. B.The Earth absorbs sunlight and reemits it in the ultraviolet.  C.It would be beneficial to humanity to develop technology that would eliminate the greenhouse effect on Earth.  D.If there were no greenhouse effect, liquid water would not exist on the surface of the Earth.  E.The more carbon dioxide there is in an atmosphere, the stronger the greenhouse effect will be.
