How does magma come about? Is it permanently extinguished?

This is more troublesome in detail, I can't say clearly, simply put, the magma comes from the earth's core, and the earth's core has been moving (or it is better to burn), so the magma will never be extinguished, just like the sun, the earth's core is very hot, some heat will not reach the surface, but there are very close to the surface, there are hot springs, but just like people, people will be angry, and the magma in the core must also have a place to vent (you hold your breath for a long time and don't scatter???) So it will erupt out of the volcano.

The magma will be extinguished after it erupts, and the ** of the magma.

Jiang Fashi argued in the article "A New Theory of the Earth":

Magma is divided into primary magma and regenerated magma.

Primary magma is formed from molten material trapped by the Earth's core. The Earth's core traps molten material and some other materials to form a huge thick molten layer. The composition of these substances is uneven. The primary magma solidified to form the most primitive earth's crust.

The various intrusive rocks we see, such as ultramafic rocks, mafic rocks, neutral rocks, acidic rocks and alkaline rocks, as well as various types of magma erupted by volcanoes, are all regenerated magma, but the depth of the channel, the material composition and the degree of differentiation are different.

Regenerated magma includes magma mutated from primary magma and relava magma.

The Earth's liquid layer is made up of regenerated magma formed by mutation of primary magma – formed by changes in temperature, composition, and state of matter.

The energy source for the evolution of the planet has always been an unsolved problem. There is no exact answer to the question of plate movements and other well-known Earth movements and phenomena, such as the formation and maintenance of the Earth's magnetic field, Chandler's shaking and other uneven movements of the Earth's rotation, volcanic activity, stratification and thermal movement in the Earth's interior, the release of geothermal flows, and so on. However, in the formation of the Earth and a series of evolutionary processes, the generation, migration, transformation and digestion of energy played a decisive role.

It can be said that finding the energy of the Earth's evolution** is equivalent to solving the main problem of earth science. The theory holds that the energy source for the evolution of the Earth is the solar neutrino.

Neutrino is a small neutral particle (1930) predicted by the Austrian physicist Pauli (1930). and it was estimated that neutrinos float on the nucleus with a cross-section of about 10 minus 43 centimeters of nucleons (1934). Kewen and Ryan proved the existence of neutrinos by the collision of antineutrinos and protons emitted by nuclear reactors (1956), and the reaction cross-sections of the neutrinos detected by the experiment are basically consistent with the estimation of and .

Based on this, physicists believe that the vast majority of neutrinos can easily pass through the Earth, as well as any other planets and stars.

Thermonuclear reactions in the Sun's interior are constantly producing a large number of neutrinos that radiate around. Standard theory predicts the release of two neutrinos during the transformation from four protons (p) to a helium nucleus. From this, it can be estimated that when solar neutrinos reach the Earth's surface, they are about 66 billion per square centimeter per second.

The energy of solar neutrinos that reach Earth in a year is: 1790 trillion gigajoules. This energy is 167 times more energy than the Earth consumes each year in the form of volcanoes, **, and surface heat flows.

Therefore, as long as a few tenths of a percent of neutrinos are absorbed by the Earth, it is enough to provide energy for the various evolutions of the Earth.

It is impossible for the Earth to produce nuclear fusion and become the Sun, because the core of the Earth is iron, and the iron atoms are the most stable.

If it were Jupiter, it would be possible.

Magma flows from the interior of the earth's crust and originates in the mantle and deep into the earth's crust; The part of the magma that erupts out of the surface can be cooled, and the part that does not eject but enters the interior of the rock layer also cools to form intrusive rock. Second, the part that originates in the asthenosphere does not cool.

Explanation 1: When a volcano is active, not only steam, stones, crystalline debris and molten lumps are ejected from the crater, but also hot and viscous molten material overflows from the crater. The former is called volatile and pyroclastic material, while the latter is called lava flow.

At present, we call this molten material that is produced deep in the upper mantle and crust and contains volatile substances and is mainly silicate.

Explanation 2: Refers to molten or partially molten rocks underground. When magma erupts from the earth's surface, it is called lava. The magma that erupts from the surface becomes the ejecta rock; Intrusions into the earth's crust are called intrusive rocks.

When water meets magma, it turns into steam. The water liquid absorbs heat and then turns into steam. In this way, the heat of the magma will be continuously absorbed by the token, and the magma will slowly cool.

Hot melt resulting from the partial melting of material deep in the earth's crust or upper mantle. The composition is complex, mainly silicate, containing a certain amount of volatile components, and there are two ways to quench milk block magma. The square tampering method is as follows:

1 .The first way is to block the lava with blocks. As long as the source is blocked, the magma will not flow out again.

2.The second method is to pour water on the magma, which then condenses into black crystal.

Oxygen is required for fire to burn, and the heat emitted by oxygen during combustion is not enough for water to evaporate. Magma is a special substance that does not require oxygen to burn itself, with a minimum of 500 degrees and a maximum of 1200 degrees, and seawater can only cool its surface.

Because the principle of water extinguishing fire is to block the oxygen that can be burned, but magma eruptions are due to the high-pressure movement of the earth's crust and do not need oxygen in the air. Magma is formed by the movement of the earth's crust that causes the liquid gases stored at high temperatures and pressures under the earth's crust to erupt.

Magma is a hot, viscous silicate melt that naturally forms in the interior of the earth and contains certain volatile components. When water encounters magma at high temperatures, it will directly volatilize into water vapor. Moreover, magma is completely different from ordinary open flames, which are caused by oxidation, while magma is a fluid substance with high temperature properties, and it does not need the help of oxygen to burn itself, and the eruption of volcanoes is related to the movement of crustal plates, so it cannot be stopped.

I think the temperature of the magma is very high, and the water will evaporate before it touches the magma. Magma is formed because of the thermal insulation of the earth's crust and the heat generated by internal movement friction that melts the rocks, and it has a high temperature.

Water can extinguish fire, but it can't extinguish magma because the magma material contains not only flames, but also other liquid substances.
