Hello, everyone, I am a fat duck.

We have known since childhood that fire and water are incompatible, but in the vast world of the deep sea, there is actually a scene of "Flame Mountain". In the mid-Atlantic ridge, there is a high-temperature hydrothermal vent, which allows us to see the scene of fire and water blending.

In 2005, Professor Andrea, a geochemist from Jacob University in Bremen, Germany, and her research team discovered a high-temperature hydrothermal vent in the mid-Atlantic ridge. The lowest temperature of the water around this spout is 407℃, and the highest temperature is as high as 464℃, which is the highest temperature water found by human beings on the earth so far.

Supercritical water refers to water when the air pressure and temperature reach a certain value, and the density of water expanded at high temperature is exactly the same as that of water vapor compressed at high pressure. At this time, there is no difference between liquid and gas in water, they are completely fused together and become a new high-pressure and high-temperature fluid. Supercritical water, mixed with oil and other substances, has extensive fusion ability. These characteristics enable supercritical water to produce strange functions.

It turns out that the hydrothermal solution discovered by scientists is deep in the seabed, and the pressure on the seabed is extremely high. When seawater expands and separates in the earth's crust and seeps into the ground to meet hot high-temperature magma, in this high-pressure and high-temperature state, the density of high-temperature expanded water is exactly the same as that of high-pressure compressed water vapor. At the same time, the temperature in the deep sea is extremely low, generally only about 2℃, but some seabed is affected by geothermal heat, and the temperature may be as high as 300, which will meet the requirement of forming "supercritical water". Therefore, supercritical water can be formed on the seabed in some areas.

Hydrogen peroxide and sulfur at the bottom of the sea meet with supercritical water, and there will be a golden wind and jade dew. In the wonderful nature of supercritical water, crimson flame and deep seawater reflect each other, forming the scene of "Flame Mountain" on the seabed.
