source form earth water The subject of longstanding debate in the scientific community, as one of the most pressing questions in scientists’ ongoing effort to understand how life originated, Lawrence Livermore National Laboratory scientists believe. (LLNL) That they have the answer to the source of the water on the planet, thanks to the study of moon rocks.
According to the website,RT“It is because the Earth-Moon system was formed together from the impact of two large bodies very early in the history Our solar systemTheir history is closely intertwined.
Also, given that the Moon lacks plate tectonics and weathering conditions (the process of breaking down and decomposing rocks, soils, and minerals), processes that tend to erase or obscure evidence on Earth, the Moon is actually a great place to look for clues to Earth’s water history..
Although approximately 70% of the Earth’s surface is covered by water, our planet is generally a relatively dry place compared to many other bodies in the solar system, and the Moon is drier.
The traditional theory was that the lack of volatile species (such as water) on Earth, especially the moon, was due to a violent effect that caused the exhaustion of the volatile elements (the evaporating elements)..
But by looking at the isotopic composition of the lunar rocks, the team found that the objects involved in the impact that shaped the Earth-Moon system had very low levels of volatile elements before the collision, not because of it..
Specifically, the team used the relative amount of the volatile and radioactive isotope rubidium 87 . (87Rb)which was calculated from its sister counterpart strontium 87 (87Sr)to determine the weight of rubidium in the Earth-Moon system when it was formed.
The team found that because 87Srwhich is representative of the moon’s fluctuating long-term budget, was so low that the colliding bodies had to be dry at first, and not much might be added since then..
The scientists, led by cosmologist Greg Brenica, concluded: “Earth was born with the water we have, or we hit something that was primarily water.” (H2O) Pure, with nothing else in it. This action removes meteorites or asteroids as potential sources of water on Earth and strongly points towards rebirth with this (blessing) water.“.
In addition to significantly narrowing the potential source of Earth’s water, this work also reveals that the large objects that collide must have come from the inner solar system, and the event might not have occurred before 4.45 billion years, greatly reducing the time of the formation of the Moon..
According to Lars Burg, the study’s lead author: “There were only a few types of material that might combine to form the Earth and the Moon, and it wasn’t strange, it’s likely that both were just large bodies that formed roughly in the same region that happened to smash into each other more than a year later. A little 100 million years following the formation of the solar system..but we are fortunate that they did exactly that “.
