Why does the desert become cold at night? 1
When going to large deserts in the world such as the Sahara in North Africa, people will often bring a lot of jackets and sunscreen to avoid sunburn.
In arid deserts like the Sahara Desert or the Atacama Desert in Chile, the humidity, the amount of water vapor in the air, is practically zero.
Air with high humidity also requires more energy to heat up, which means it also takes more time for that energy to dissipate and help the surrounding environment cool down.
Or to put it another way, at night there is no heat from the sun to warm up these large sandy beaches, so the temperature will drop very quickly.
When the atmosphere is extremely cold, it means these sandy beaches don’t have much moisture.
As a result, most of the plants that grow here are short and squat, such as shrubs close to the ground, and there are very few large mammals because they are often unable to store enough water.
Despite erratic temperature changes in desert areas, many species of animals and plants still adapt and grow well.
Reptiles are known to be the most abundant and diverse group of animals in the desert, adapting well to extreme temperature changes.
However, large warm-blooded or endothermic mammals such as camels have large body sizes, making it difficult to find places to hide from the sun and reduce their body temperature.
Meanwhile, plants are more vulnerable in desert environments because they cannot move.
