What is one major reason for high daytime evaporation in desert regions?
Answer and explanation
Correct answer: High temperature and low humidity
During the day, desert temperatures are very high, giving water molecules more energy to escape as vapour. The air is also low in humidity, so it can accept more water vapour; therefore, evaporation is rapid. Low temperature and high humidity would have the opposite effect and reduce evaporation. Exam tip: evaporation increases with higher temperature and lower relative humidity.
