The neon isotopes of glass rocks in the ocean floor can help to understand the formation of the Earth 4.5 billion years ago.
According to the speed at which the primitive form of our planet comes from the solar nebula, scientists say that the concentration of different gases on the Earth will be different.
A new study that breaks down the neon in the depths of the ocean shows that the Earth was born quickly from clouds of dust and gas around the sun, with water and gases trapped in the center.
The study proposes three pioneering ideas on land formation from different trajectories and temporal processes.
While the first idea suggests that the process has unfolded quickly, over a period of two to five million years, another idea indicates that the Earth is made up of dust particles that shine the sun and rise. condense into mini asteroids before they appear.
The third idea is that the formation of the Earth was a slow process that relied on cosmic meteorites rich in water to deliver gases.
"We are trying to understand where and how neon was acquired in the Earth's mantle, which tells us how fast the planet is and under what circumstances," said researcher Curtis Williams of the University of California at Davis .
New discovery on how to start life on Earth
Williams explains how neon can settle in water, carbon dioxide and nitrogen when looking for its origin.
Neon, unlike other biochemicals, is inactive, which means that it does not change as a result of chemical and biological processes.
"Neon keeps the memory of its origin even after 4 ½ billion," says Sujay Mokobadale, a professor at the University of California at Davis.
In this study, the team measured isotopes of neutrons, which remained stuck in the mantle during the formation of the Earth.
