Why nights are cooler in deserts

This is the major cause that deserts can be hot during the day but cold during the night. The deficiency of plants and water bodies allows sun rays to be engrossed into the desert surface. Then the surface returns this heat to the environment causing high atmospheric temperatures.

Deserts can get actually warm throughout the day, but cold downward quickly to be cold at night. Deserts are cold by night as the cloudless skies allow the daytime temperatures to escape quickly after nightfall. When the atmosphere is extremely cold it will not have much humidity. Hot and dry deserts have a mean yearly warmth of 20 to 25 degrees Celsius, and the tremendous temperatures can range from 43 to Thus, areas in the polar region that have very cold air will not receive considerable rainfall.

Because of the heat and the deficient in of precipitation, there are no huge shade trees to shade animals or plants. Most plants are stubby in height, such as ground-hugging shrubs, and there are very few large mammals because they are often not competent in storing enough water. That's because temperatures in the Sahara can plummet once the sun sets, from an average high of degrees Fahrenheit 38 degrees Celsius during the day to an average low of 25 degrees Fahrenheit minus 4 degrees Celsius during the night, according to NASA.

So, why does this dramatic temperature shift happen in arid deserts like the Sahara? And how do native animals and plants deal with such wild extremes? Related: Could the Sahara ever be green again? The planet we live on is a remarkable place. But have you ever wondered how or why these things occur? How the Earth was made? How we predict the weather? How fossils form?

What causes earthquakes or which animals glow in the dark? Unlike a thermos, sand doesn't retain heat very well. When heat and light from the sun hit a sandy desert, sand grains in the desert's top layer absorb and also release heat back into the air, according to a report from NASA's Jet Propulsion Laboratory in Pasadena, California.

During the day, sand's radiation of the sun's energy superheats the air and causes temperatures to soar. But, at night most of the heat in the sand quickly radiates into the air and there is no sunlight to reheat it, leaving the sand and its surroundings colder than before. However, this phenomenon alone doesn't account for such a drastic drop in temperature.

Which of the following is a type of farming that involves both the growing of crops as well as raising of livestock? Login into Examveda with Login with Facebook. Nights are cooler in the deserts than in the plains because Sand radiates heat more quickly than the earth B.

The sky remains clear most of the time C. Sand absorbs heat more quickly than the earth D. None of the above reasons Answer: Option A Solution By Examveda Team Nights are cooler in the deserts than in the plains because Sand radiates heat more quickly than the earth. Because deserts have such little water vapor in the air, it makes it harder to trap heat or cold in a desert.
