Most of the planet's daylight is radiated by oxygen from the atmosphere.

Summary

When we see the difference of daylight on planet earth and on the moon, we ask ourselves why is there lighter on earth? If the earth and the moon are almost the same distance from the sun, so they should have similar daylight. According to this research the answer is that the moon and the earth receive the same amount of radiation from the sun per m2, but the greater amount of white light we see on earth is due to ultraviolet light that is radiated as white light by oxygen from the atmosphere. On the moon as there is no oxygen, because it has no atmosphere, the white light we see is received directly from the Sun,

Introduction,

The planet is experiencing increases in temperatures, and in order to know the causes of this phenomenon, we should better understand the daylight where the planet's highest temperatures occur. This paper explains that most of the white light does not come from the sun, as it is believed, but from the oxygen present in the atmospheres of the planets, which by absorbing the ultraviolet light of the sun and it radiates as white light within the planets. Although the earth's atmosphere is composed mainly of nitrogen at 78%, and oxygen is only 21%, we cannot attribute white light to nitrogen, because this gas is invisible to ultraviolet light. In contrast, oxygen absorbs much of the sun's ultraviolet rays, as seen in laboratory experiments.

Definitions

Daylight is the combination of all direct and indirect sunlight during the daytime. This includes direct sunlight, diffuse sky radiation, and (often) both of these reflected by Earth and terrestrial objects, like landforms and buildings. Sunlight scattered or reflected by astronomical objects is generally not considered daylight. Therefore, daylight excludes moonlight, despite it being reflected indirect sunlight. (1)

The composition of the Earth's atmosphere.

The atmosphere of the planet is made up of 78% of nitrogen which is an inert gas that usually does not react with other substances. 21% oxygen, which is a highly reactive gas. 9% argon, and 01 percent of other gases.

Almost the whole of the air (95%) has less than 30 km high, being more than 75% in the troposphere. The air form in the troposphere a mixture of gases homogeneous to the point that their behavior is equivalent to that which would have if it were composed of a single gas.

• Nitrogen: constitutes 78% of the volume of air. It is composed of molecules that have two nitrogen atoms, so that your formula is n2. It is an inert gas, i.e. that usually does not react with other substances.

• Oxygen: represents the 21% of the volume of air. It is formed by molecules of two atoms of oxygen and its formula is O2. It is a gas very reactive and most of the living beings need to live.

• Argon: contributes in 0.9% of the volume of air. It is a noble gas that does not react with any substance.

• Carbon dioxide: it is composed of molecules of a carbon atom and two oxygen atoms, so that your formula is CO2. Represents the 0.03 per cent of the volume of air (2)

Oxygen

Is a chemical element of atomic number 8 and represented by the symbol O, under normal pressure and temperature conditions, oxygen is a colorless and odorless gas with O2 molecular formula, in which two oxygen atoms are linked to the electronics of Triple-State configuration. This link has a two-link order and is generally simplified in the descriptions as a double link or as a combination of a two-electron link and two three-electron links. (3)

Development

We know that oxygen is a gas that makes up 21% of the atmosphere, which is highly reactive, and which largely absorbs ultraviolet radiation from the sun, and we know that the reaction of this process is that the atmosphere re-radiates white light, but heat is also caused, by increasing the kinetic energy of the molecules they contain in the atmosphere by increasing the speed. This process that originates between the oxygen of the atmosphere and the ultraviolet of the sun, is overlooked, because the climate of the planet is explained by a greenhouse effect caused by the co2 and infrared emitted by the earth.

Conclusion;

We can conclude that when the sun's ultraviolet radiation is absorbed by the oxygen in the earth's atmospheres, it in turn radiates it in the form of white light, the same would be true in the atmospheres of the planets of the solar system that have some oxygen. On the moon as there is no oxygen, because it has no atmosphere, the white light we see, this is received directly from the sun.

The process of ionization of oxygen in the atmosphere of the planets also causes heat. So we can conclude that in the lower part of the earth's atmosphere, known as the troposphere, where 75% of all oxygen is found, the white light and heat should be greater than in any other layer of the atmosphere.
