How is water vapour in the troposphere compared with that in the higher atmospheric layers?
Answer and explanation
Correct answer: More
The troposphere contains the greatest share of atmospheric water vapour because it is closest to Earth’s surface, where evaporation adds moisture to the air. As this moist air rises, it cools and may form clouds, precipitation, and other weather phenomena. Therefore, option A is correct. The other choices are incorrect because water vapour is not completely absent, restricted to the poles, or limited to nighttime.
