How does water vapour distribution vary because its source is mainly Earth’s surface?
Answer and explanation
Correct answer: More in the lower atmosphere and less at height
Most atmospheric water vapour enters the air through evaporation and plant transpiration near Earth’s surface. As moist air rises, it cools, condenses and loses water through clouds and precipitation; mixing is also limited at great heights. Consequently, water vapour is generally much more abundant in the lower atmosphere and decreases upward. Option A is correct.
