In deserts days are very hot and night are very cold why?
(long Question) ​

Sands are very good absorbers of radiation and at the same time sands are very good radiators. At day time sands absorb heat from the sun and become very heated. Since they are very hot, so they radiate a large amount of heat.

At night, sands radiating heat cool quickly. As a result, at night, people feel extremely cold.

Desert is hot throughout the day because of lack of water and desert are cold throughout the night because sand cannot hold heat, so for the period of night when the sun is not shining the sand loses all its heat and compose desert cold. So during the night when the sun is not unblemished, the sand loses all its heat, making the desert night cold. Sand is the main cause why deserts are hot during the day and cold throughout the night.

Explanation:

Deserts are hot during the daytime because of the sand –

Because sand cannot hold heat, it needs a stable source of energy to stay warm (The Sun). In the deserts, the sun rays reach the surface of the earth at almost right angles during summertime. The heat that radiates from the sun and heats up the land begins to heat up the air and then escapes into the environment due to the lack of clouds and moisture. The heat is consequently resolute over small areas of ground which gives immense heat. Daytime temperatures are high due to no cloud or humility to help block the sun rays. 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 are hot for two reasons:

Because of the deficient in of water, deserts cannot maintain many plants. This plant life in photosynthesis cools the earth around it.

Sand cannot hold heat. The sun on a desert shines just as bright as it shines everyplace else, but sand just acts as a reflection of the sun.

carbon is found in all living things. carbon atoms move constantly through

living organisms, the oceans, the atmosphere, and the earth’s crust in what is

known as the carbon cycle. the directions taken by carbon atoms through this

cycle are very complicated and can take millions of years to make a full circle.

all animals, from humans to the dinosaurs are part of the carbon cycle. when

animals eat food, they get carbon in the form of carbohydrates and proteins.

in animals, oxygen combines with food in the cells to produce energy for daily

activity and then gives off carbon. the carbon combines with oxygen to form

carbon dioxide (co2) and is released back into the atmosphere as a waste

product when animals breathe and exhale.

from 145-65 million years ago, earth was much

hotter than today and covered with dense,

tropical swamp forests. the trees and other

plants were immense and

provided an endless supply of

food for the giant animals that

roamed the land. somewhere in

the air above one of these

forests, a lone carbon atom has joined

up with two oxygen atoms to form a molecule of co2.

the co2 molecule was sucked into the tiny holes (stomata) on the leaf of a

fern plant and joined with sunlight, chlorophyll and water to make food and

energy in the plant’s cells through photosynthesis. the oxygen (o2) from the

co2 molecule was sent back into the atmosphere; the carbon atom (c) was

detached and used to make a molecule of sugar.

if that carbon atom had been eaten instead, a totally

different situation would have developed. let’s say

that a giant plant-eating dinosaur (herbivore) ate the

fern for breakfast, and swallowed the carbon in the

fern in the form of carbohydrates and proteins. in

the process of respiration, oxygen combined with

the carbohydrates and proteins in the dinosaur’s cells

to provide energy for its daily activity.
