Why does the amount of water vapour generally decrease with height?
Answer and explanation
Correct answer: Because its main sources are Earth's surface and water bodies
Most atmospheric water vapour enters the air through evaporation from oceans, lakes, soil, and other surfaces, along with transpiration from plants. These sources are concentrated near Earth’s surface. As moist air rises, it cools, condensation and precipitation remove water, and less vapour remains at greater heights. Therefore option B is correct; the other choices identify impossible sources or processes.
