Why is water vapour low in dry desert air?
Answer and explanation
Correct answer: Because moisture and evaporating water sources are limited
The controlling concept is the availability of moisture in the lower atmosphere. Deserts generally receive little rainfall and contain few rivers, lakes, or other accessible water sources, so there is less water available for evaporation. Dry air also tends to have low relative humidity. Therefore option A is correct; nitrogen is still present, ozone is not the cause, and argon does not produce rainfall.
