The days are scorching hot, the nights presents a stark contrast. So, why are desert nights cold?
The reason behind this is a combination of two factors: Sand and humidity.
According to the information,sand lacks the ability to retainheat effectively. When the sun'sheat and light reach the desert,sand grains absorb andsubsequently release this heatinto the air.
During the daytime, the sand grains continuously absorb and release heat, maintaining the hot environment.
However, during nighttime, the sand grains rapidly release their stored heat in the air. And with no sun to replenish the heat, the desert nights grow colder.
