Solution(By Examveda Team)

Nights are cooler in the deserts than in the plains because Sand radiates heat more quickly than the earth. Because deserts have such little water vapor in the air, it makes it harder to trap heat or cold in a desert. At night, the sun no longer heats the desert and the heat from the day doesn't stay trapped. Because of this, some deserts can get cold at night, dropping to below 40F, which is definitely coat weather.
