Scientists: The Earth was dry when it was formed

Now researchers at the California Institute of Technology offer a third theory about the arrival of the water.

from one Stady The Earth’s inner magma shows that the planet was very dry in the early stages. This indicates that water did not appear on Earth until a later stage.

The researchers concluded that a significant supply of materials necessary for the origin of life, such as water, occurred only during the last 15 percent of the time it took for Earth to form.

Magma reveals its origin

According to American research, the Earth was formed from hot, dry materials.

Although we cannot go deep into the Earth, we can examine magma that has reached the Earth’s surface from different depths in the form of lava.

Just as fossils contain information about Earth’s biological past, magma contains chemical data—known as “fingerprints”—that give us an indication of when Earth formed.

So the American researchers took samples of magma from different depths, and the chemical traces from the inner mantle showed a lack of so-called volatiles – substances that evaporate easily, such as water and iodine.

At the same time, the results showed that the Earth’s outer mantle contains three times as many volatile substances as the inner mantle.

Travel to Earth – and understand Manti better

The researchers hope that the findings will help solve the mystery of how other planets appeared, not just on Earth.

“We need to study this subterranean world of magma to better understand how rocky planets like Earth formed,” Tissot concludes.

Mars, Mercury, and Venus are also rocky planets, and are believed to have formed from dry material in the same way as Earth.

The researchers also hope that their study will contribute to a better understanding of the possibilities of life on other rocky planets.

“Space exploration for rocky planets is really important because a world with water is probably the best place to look for life in space,” said François Tissot, assistant professor of geochemistry at Caltech.
