B)The relative humidity would always be high.
C)The saturation vapour pressure would be low.
D)The evaporation rate would be low.

Question

Quizplus · Accepted Answer

Hot, dry air has a very low water vapor content, so the specific humidity would also be very low above the desert during the daytime.

Answer: C
 Saturation vapor pressure is the maximum vapor pressure that can be reached at a given temperature. In hot, dry air, the temperature is high, which means the saturation vapor pressure is also high.

Answer: D 
 The evaporation rate would be high above the desert during the daytime because of the high temperature, low humidity, and strong solar radiation.
