during the night. Give reason.)

Answer 1

It is actually sand, which turns the entire phenomenon hot. Sand cannot hold the heat. It acts like a mirror to the sun. During the daytime, it stays warm, and when the Sun is absent it loses all its heat making the nights colder. There’s nothing in the desert that can either absorb heat from the sun or hold it on the surface when the sun is set.

Answer 2

Because deserts have such little water vapor in the air, it makes it harder to trap heat or cold in a desert. And 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 extremely cold at night, dropping to temperatures below 40F.

Hope this helps!! Have a wonderful day!!
