Water can extinguish fire, but why can t it extinguish magma?

Because of magma. The temperature is too high, and the water becomes water vapor as soon as it is poured on it.

It's not extinguished. For example, there are many volcanoes on the ocean floor, and there are many active volcanoes among them.

Because volcanoes are mostly found in areas where the earth's crust is thin and unstable, and the ocean is not only thin in the crust, but also has great ups and downs, sometimes sinking in areas thousands or tens of thousands of meters deep, forming ocean trenches; There are also special uplifts, which form submarine seamounts. Volcanoes love this kind of place, and when it finds an opportunity to erupt, no amount of water can stop it.

The sea water does not extinguish the volcano because the temperature of the volcano is high and the volcano is hot magma.

A hot melt produced by the partial melting of volcanic magma, deep crust or upper mantle material. The composition is complex to silicate.

It is mainly composed of a certain number of volatile components and has a certain viscosity.

In different layers of the earth, magma with different compositions and physical and chemical properties can be formed, such as ultramafic and mafic magma formed in the deeper part of the ground, and the temperature is higher, about 1000 1200; The acidic and neutral magma formation site is relatively shallow, and the temperature is relatively low, about 700 1000 . Soviet scholar Levinson.

Lesinger. It is believed that there are two types of magma – granite magma and basalt magma. Rittman divides into:

primary magma; secondary magma or remelted magma; Same as lava magma; Mixed magma. Magma has a high temperature and pressure inside the earth's crust, and under the influence of tectonic movements or other internal forces, it can invade the weak part of the earth's crust or eject out of the earth's surface, and form various igneous rocks through condensation and consolidation.

In short, magma is rock that melts at high temperatures.

When water meets magma, it volatilizes directly into water vapor at high temperatures.

Because the temperature of fire and magma is not the same, water can extinguish the fire because the temperature of the fire is low.

Because the temperature of the magma is so high, it can evaporate the water in an instant.

The temperature of the magma is too high, and it needs a lot of water.

Because the amount of water is not enough to extinguish the amount of magma.

Magma erupts from a volcano and is a fluid substance with high-temperature properties.

Because there is not enough water to extinguish the magma.

Because magma is also considered liquid, and there are a lot of them.

There are so many fires together, and the temperature is so high, it definitely can't be extinguished.

Because the temperature of magma is much higher than that of fire.

Water can extinguish fires, why can't seawater extinguish mountain magma, only cool down?

It stands to reason that yes, it's just a matter of how much.

Water cannot extinguish lava.

Magma is a hot, viscous silicate melt that naturally forms in the interior of the earth and contains certain volatile components. But water can really extinguish fire, but it can't extinguish magma, it can only achieve a cooling effect.

For example, when an undersea volcano erupts, the "fire" that erupts is relatively special, and this "fire" is also a process of releasing energy during the eruption.

However, its peculiarity lies in the fact that the energy it releases does not come from chemical energy, but from the thermal energy contained in the depths of the earth, and it does not need oxygen to **, so it does not need water to isolate its oxygen**.

Introduction to Magma Activity:

During the eruption of lava flows, a large amount of volatiles will be lost due to the sudden drop in pressure, so it is not really magma, but only the material closest to magma. Magma can move to different depths of the earth's crust with crustal activity to condense and crystallize, or it can spill to the surface to condense and consolidate.

The whole process from the generation of magma to the condensation and consolidation of magma into rock is called magmatic activity or magmatic action, and the magmatic activity that erupts from the surface is called volcanic activity or volcanism. Magma turns into lava when it comes into contact with air.

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.

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.
