The current Earth's atmosphere is 78% nitrogen N2, 21% oxygen O2, about 1% argon Ar and 0.03% CO2. Generally, oxygen is said to have been made by plants, especially by phytoplankton. Iron bacteria, cyanobacteria acted gigantically in the sea of Earth 3.5 billion years ago, and produced oxygen and iron ore floor. Iron ore floor made by cyanobacteria is called striped iron ore and is widely distributed throughout the world.

However, in the photosynthesis of plants, in the presence of sunlight, oxygen and starch are made from carbon dioxide and water. In the absence of sunlight, it absorbs oxygen and releases carbon dioxide. Also, the remains of plants consume oxygen when they break down. It is impossible for plants to increase atmospheric oxygen by photosynthesis. Even if it is cyanobacteria, if it occurs in large quantities, it will consume oxygen when its remains erode.

So what made the current oxygen? Nitrogen is also a few element in the solar system. The origin of nitrogen has not been elucidated yet.

By the way, in Earth's interior, I explained that olivine changes phase, making carbon dioxide and water. "Olivine inside Earth releases a large amount of electrons" On the other hand, about 100 muons are falling on the ground surface per 1 m ^ 2 per second from High Energy Cosmic Ray . Muon bounce electrons when it hits atmospheric carbon dioxide and reside between oxygen atoms and carbon atoms instead of electrons. Since muon has a size about 200 times larger than the diameter of the electron, oxygen nucleus and carbon nucleus fuse together. Muon fusion. There are 6 protons and neutrons for carbon and 8 for oxygen. When both are combined, 14 protons and 14 neutrons are obtained. Nitrogen has atomic number 7.

Nitrogen and oxygen are formed at a ratio of 2: 1. In this state, nitrogen 66%, oxygen 33%, but because oxygen has high reactivity, it may be that oxide is made and it decreases from the atmosphere. It should be soluble in seawater.

Also, 14 protons and 14 neutrons can produce oxygen and carbon isotopes. These two isotopes are used to estimate dating and temperature variation in archeology. If transmutation by muon is confirmed, it has to be reviewed. Because the evidence that the ice age occurred is fluctuating. The muon has high permeability, so it reaches the ground as well. Due to muon fusion, it is possible that heavy elements are made inside Earth.

CO2 concentration and muon

Electrical Earth science predicts that carbon dioxide is transmutated to nitrogen and oxygen by muon fusion. For example, the seasonal change in carbon dioxide concentration is observed in detail, in the northern hemisphere the concentration is lowest in August and peaks in February of winter. It is explained that this change is caused by human consumption of fossil fuels.

There was data that observed mu particles for 5 years. According to this, mu particle decreases the most in February and peaks in August.

In other words,CO2 concentration becomes the largest in February when the mu particle decreases, and CO2 concentration decreases in August when muon increases. There is a great correlation.

Earth approaches the sun most in January and leaves in July. There is about 5 million km difference. When approaching the sun, the influence of the solar magnetic field increases, so cosmic rays derived from the galaxy decrease. Muon  made by collision with the atmosphere are also reduced. Muon fusion also decreases.

CO2 not only burns fossil fuels, but also from oceans, forests and soils. It is the volcano that gives off the most amount of CO2. There is no sudden change in the degree that human beings burned oil somewhat. Muon nuclear fusion influenced the concentration of CO2.
