Which pair correctly represents a permanent gas and a variable component?
Answer and explanation
Correct answer: Oxygen and water vapour
A permanent gas has a relatively stable proportion in clean, dry air over broad regions, whereas a variable component changes considerably with place and time. Oxygen is treated as a permanent atmospheric gas, while water vapour varies with evaporation, temperature, humidity, clouds, and rainfall. Option A therefore gives the correct order. The other pairs contain two variable or suspended components and do not provide the required classification.
