Question

Quizplus · Accepted Answer

This statement is true. Most of the Earth's water vapor is found in the lower atmosphere, specifically in the first 10 kilometers of the atmosphere. This is because the lower atmosphere is closer to the Earth's surface and contains more water vapor due to evaporation, transpiration, and other processes. As the altitude increases, the air becomes colder and drier, which reduces the amount of water vapor in the air.
