When the disc-shaped material revolving around the sun formed the earth, hydrogen entered the place that would become the core of the earth.
After reading Jules Verne’s science fiction novel “Journey to the Center of the Earth”, do you also want to go to the center of the Earth? Don’t worry, learn to swim first. A new study found that the center of the earth may contain most of the water on the earth, much more than the ocean on the surface.
More than 4.5 billion years ago, the earth was formed by the aggregation of hydrogen, dust, and other materials orbiting the newborn sun. During the formation of the earth, its hydrogen, a component of water, may have entered the forming core of the earth. Or, these gases may stay in the layer that eventually cools into a rocky mantle.
Recent studies have shown that the earth may have obtained a large amount of water from the hydrogen-rich solar nebula in the early stages of its evolution, and a large amount of water in the earth may have split into the core. Current estimates of the budget and distribution of the Earth’s water are largely uncertain, most of which are due to lack of information about the depths of the earth. The researchers tried to simulate what happened by analyzing the behavior of hydrogen under high pressure and high temperature, similar to the hydrogen found on the boundary between the mantle and the core.
The author estimated the temperature and pressure of the boundary and how hydrogen would react under these conditions. They found that under the core-mantle differentiation and the core-mantle boundary conditions, the ferrophilicity of water decreases with increasing temperature; however, under the conditions of core formation, water is always strong for reduction and oxidation conditions. Divide into molten iron. The empirical counting method of calculating the distribution of hydrogen in the equilibrium ferrosilicate melt has also verified the ferrophilicity of water.
The researchers concluded that the core of the earth may play the role of a large reservoir, containing most of the water on the earth. More than three-quarters of the hydrogen in the early Earth may have entered the core. These findings explain to some extent the low density of the earth’s core revealed by measuring seismic velocity.
