Why are deserts hot during the day and cold during the night?
Transcript of Why are deserts hot during the day and cold during the night?
Deserts are hot for two reasons:
1. Because of the lack of water, deserts cannot support much vegetation. This vegetation in photosynthesis cools the earth around it.
2. Sand cannot hold heat. The sun on a desert shines just as bright as it shines anywhere else, but sand just acts as a mirror of the sun. Deserts are cold during the night because of the sand.
Because sand cannot hold heat, it needs a constant source of energy to stay warm (The Sun). so during the night when the sun is not shining the sand loses all its heat, making the desert night cold. Sand is the biggest reason why deserts are hot during the day and cold during the night.
So blame this stuff
