5 points At a wavelength of about 14.3 microns, the atmosphere is almost totally opaque to infrared radiation because of strong absorption by C02. Viewed from a satellite in this wavelength, the radiation would be: Zero because all the energy from below is absorbed by C02 in the air Weak because the only molecules that can emit to space are very high up in the atmosphere where temperatures are very cold Strong because the sun is a strong emitter at this wavelength Impossible to measure because there are no instruments that can see that wavelength 5 points Gas molecules can absorb and emit infrared radiation by combinations of changes to their: Altitude Composition Vibrational and rotational states Concentration 5 points Almost all of the molecules in the atmosphere are: Asymmetrical, so they are good at absorbing infrared radiation Symmetrical and triatomic, so they aren't very good at absorbing radiation Chemically inert, so they are very long-lasting Diatomic and symmetrical, so they can't absorb radiation very well
