Why is the effect of atmospheric CO2 considered to depend more on its radiative properties than on its amount?
Answer and explanation
Correct answer: Because it can absorb terrestrial longwave radiation
The governing concept is the greenhouse effect. Earth’s surface emits energy mainly as longwave infrared radiation, and CO2 absorbs selected wavelengths of this radiation before re-emitting energy in different directions. Consequently, even a trace concentration can influence the energy balance and surface temperature. Option C is correct because it identifies the relevant radiative property. Sound absorption, sea-salt formation and zero air pressure are unrelated to CO2’s climatic role.
