Why is humidity generally low in desert regions?
Answer and explanation
Correct answer: Water sources for evaporation are very limited
Desert regions have very limited rivers, lakes, and other surface-water sources. Consequently, less water vapour enters the atmosphere through evaporation, so humidity is generally low. Regular moist sea winds or heavy rainfall would increase humidity, not reduce it. Exam tip: link humidity mainly with the amount of water vapour supplied by evaporation.
