Nights are cooler in the deserts than in the plains because? Answer: Sand radiates heat more quickly than the earth

Deserts have loose, dry sand which radiates heat rapidly at night, causing temperatures to drop sharply. In contrast, plains with more vegetation and moisture retain heat longer. Clear skies in deserts also contribute, but the primary reason is rapid heat loss from sand.
