Desert areas experience high daily range of temperature because

Desert areas experience high daily range of temperature mainly because the sky is cloudless. Clouds play an important role in regulating temperature because they reflect some of the incoming solar radiation back into space and trap some of the outgoing heat radiation from the earth's surface. In the absence of clouds, the earth's surface receives a lot of solar radiation during the day, which causes the temperature to rise. At night, the earth's surface loses heat radiation rapidly, which causes the temperature to drop. Therefore, in desert areas where there are no clouds to regulate the temperature, there is a high daily range of temperature, with very hot days and very cold nights.
