Lack of humidity in the air. The air contains much fewer water molecules that block out solar radiation than many non desert environments. Desert surfaces get more than twice the level of solar radiation than average surfaces because of that lack of moisture in the air.
Basically, without water in the air there is little to retain the heat energy from the sun after it has set.
Also, lack of clouds. Clouds block solar rays. Without them you receive more solar rays and all the things that come along with them (heat, etc.)

∙ 10y agoThe desert rarely has cloud cover and high humidity which act as a blanket and prevent heat from radiating into space. Therefore, the hot desert quickly loses the heat by radiation once the sun sets.

∙ 9y agoMost people tend to think of deserts as being like the Sahara Desert - baking hot sand as far as the eye can see. But, though piping hot during the day, when darkness descends, all that heat begins to rise, and with no cloud cover, there is nothing to prevent the heat from escaping out in to space. The result is a very cold desert night.

∙ 8y agoDeserts are not necessarily cold at night. However, they are much cooler than during the day. The reasons for this are that deserts have little humidity and little cloud cover to hold the heat at night. When the sun sets the solar energy absorbed by the desert during the day quickly radiates back into space.

Does desert temperatures usually show large changes between day and night?
true
What is the temperature degrees Fahrenheit at night in the desert?
Temperatures can range from -129 degrees in Antarctica to the 80s or 90s in the Mojave Desert at night in the summer.
What is the low temperature in a desert?
Temperatures vary greatly between night and day in many desert regions. Typically, humidity blocks the sun's radiation. Since deserts have little to no humidity, about twice the radiation is absorbed. At night, a greater amount of heat is lost due lack of humidity. This can bring temperatures well below freezing, especially during the winter months.
What is the variance of temperature between day and night in the desert?
That would depend upon which desert and your specific location in that desert.
What is the weather like in Somalia?
Hot, dry, dusty days in summer with high night temperatures; normally sandstorms and strong wind at the change of seasons.The Sahara is a hot desert. Because there is low rainfall and little cloud cover, a lot of heat is lost at night, so there can be a high diurnal range, with very hot days and cool/cold nights. Day temperatures can exceed 55 degrees Celsius; yet can drop below freezing at night. However, night temperatures can be very hot too.
Does desert temperatures usually show large changes between day and night?
true
Is it hot or cold and there any difference between the temperature of day and night?
Yes it is hot and cold in the desert. During the day, the desert heats up, which gives them their extreme temperatures. but at night, the desert is very cold.
What temperatures can the Kalahari Desert get down to at night?
Between May and October there is normally no rainfall. Blue sky for weeks is usual, quit warm temperatures between 18 to 22 degrees during daytime, but during the night temperatures can easily drop down to minus 7 degrees.
What is the temperature degrees Fahrenheit at night in the desert?
Temperatures can range from -129 degrees in Antarctica to the 80s or 90s in the Mojave Desert at night in the summer.
What is the day and night temperatures?
Each desert has its own statistics so you need to specify a particular desert.
Which climate is characterized by hot dry days with cooler night temperatures?
Desert
Temperatures in the desert vary greatly between the day and night The constant heating and cooling causes the rocks to crack?
yes, the process is called exfoliation
How does tourism affect the desert?
The desert is often drier than other parts of the world and the temperatures vary greatly between night and day. Deserts are considered to be inhabitable for people who have adapted to normal conditions.
What kind of weather do veiled chameleons get in the desert?
In the daytime hours, the temperatures are well above 100. but at night it is actually frezing temperatures
What desert is the coldest at night?
Antarctica is the coldest desert on earth.
Why does a desert have extreme temperature?
It is not necessarily high. The Gobi Desert is quite cold. Even the American southwest desert gets pretty chilly at night. And - believe it or not - part of Antarctica is a desert. It is the amount of precipitation that makes it a desert, not the temperature.
Do deserts have large changes in temperature on a daily basis?
Yes, due to the of the lack of humidity and cloud cover the difference between day and night temperatures in the desert can be quite extreme.
