What is the shared role of water vapour and carbon dioxide in the greenhouse effect?
Answer and explanation
Correct answer: Both contribute to absorption of longwave radiation
The governing concept is the greenhouse effect and Earth’s energy balance. The surface emits infrared, or longwave, radiation after receiving solar energy. Water vapour and carbon dioxide absorb portions of this outgoing radiation and re-emit energy in different directions, including back toward the surface, thereby influencing temperature. They do not merely form dust, drive tides, or alter Earth’s internal structure, so A is correct.
