The Earth has three parts of water and one part of earth – even so, scientists have still not been able to agree totally on a theory of the creation of this water.
A new article by Arizona State University Researchers say that water on Earth is made up of materials and gases brought in by asteroids and the remaining gases of the Sun's formation.
This study can tell us a lot about the formation of planets and their support potential.
Most of the Earth is covered with water but we still do not know the origin of the water.
Asteroid water and comet ice are not the only sources of water available
The researchers noted that since comets contain a lot of ice, it could have supplied water. Asteroids, which are not so rich in water and yet still abundant, could also be a source.
Asteroids being the water source of the Earth at the very beginning of its formation, the concept is not new. Previous studies have shown that water sources created could have survived very early during all the hot reworking of the blue planet.
This is actually the simplest explanation because the chemical signatures found in the same as those found in water on asteroids .
However, the hydrogen found in the water of the Earth is not exactly the same kind of hydrogen that found in other parts of the Earth – in especially near its source. This suggests that asteroids were probably not the only source.
"But there is another way of thinking about the sources of water in the solar system," said Peter Buseck, a professor at Arizona State University.
"Because water is hydrogen plus oxygen, and oxygen is abundant, any source of hydrogen could have served as an origin for the water of the Earth" , added Buseck.
The Earth has undergone many rapid changes at the time of its formation.
So where
The study questions the widely accepted ideas about hydrogen in the Earth's water by suggesting that the element came partly from clouds Of dust and gas subsisting after the formation of the Sun – called solar nebula.
If the abundant amounts of hydrogen in the nebula could combine with the rocky materials of the Earth during its formation, this could be the ultimate origin of the global ocean of the Earth, have said the researchers.
This argument is corroborated by a recent study The gas of the nebula could have coexisted with growing planets, which would give hydrogen the chance to integrate into the deepest parts of the planet.
"The solar nebula received the least attention among the existing theories, although it was predominant," Jun Wu, a research professor in the academic economy, said, " Hydrogen tank in our initial solar system. "
How can this new study help us better understand the birth of planets?
Current theories about the formation of Sun and planets. try to explain the origin of all the water of the Earth with a single source, the study also takes into account many factors that could have caused such a significant change.

The formation of habitable planets is not a time-consuming process as previously planned.
Astronomers have discovered more than 3,800 planets orbiting other stars and many appear to be rocky bodies not very different from ours.
The Research Team attempts to collect more data samples in the Earth's mantle to support the new Study and also advance with laboratory experiments to understand the processes in more detail such as they could have occurred under the atmospheric conditions existing at the beginning of the Earth.
