Question

Why is there such a large difference in daytime and nighttime temperatures in deserts?

Answer 1

Generic answer :

The temperature in the desert can change drastically from day to night because the air is so dry that heat escapes rapidly at night.

Extra fact :

You could also say that another factor is because of the lack of clouds, there is no barrier between the sky and the earth, leading to direct sunlight and very cold weather ( at different times ).

Answer 2

The primary reason for the large difference in daytime and nighttime temperatures in deserts is due to the low humidity and lack of clouds in the atmosphere. During the day, the sun's radiation is absorbed by the ground and air, leading to high temperatures. At night, the air and ground cool quickly because there is no humidity to trap the heat. This leads to a large temperature difference between day and night in deserts.
