The Moon Is Essential For The Existence Of Water On Earth

Since the early days of humanity, the moon was a source of fascination and mystery. A new study claims that the collision between the Earth and a dwarf planet, an event which took place almost 4.4 billion years ago, resulted in the accumulation of a large amount of carbonaceous material which can explain the presence of water across our planet.

The discovery suggests that without the moon water wouldn’t have appeared on Earth. In the absence of this essential element, it is likely that life wouldn’t have existed.

Our planet is quite different in comparison to the other ones found in the solar system since it is the only one with a vast reserve of water and a moon that can stabilize its axis. Both traits are vital for the development of life. The new study shows how the water found its way towards Earth as the moon formed.

The moon is needed for the existence of water on Earth

The researchers are also walking on a new theory which infers that a large amount of the molybdenum found in the mantle of the Earth comes from protoplanets called Theia, which clashed with our planet 4,4 billion years ago, leading to the formation of the moon. The chemical structure of the molybdenum suggests that Theia may have come from the outer solar system.

It is well-known that Earth formed in the so-called dry section of the solar system, which made the existence of water on the planet a mystery from many researchers. Previous studies suggested that water may have been brought to earth by carbonaceous meteorites, which carry a large amount of liquid.

To solve the enigma, the team decided to survey the molybdenum isotopes, which allowed them to differentiate between non-carbonaceous and carbonaceous material, offering an important glimpse into the past. It is now believed that the impact with Theia provided the material needed for the appearance of all the water which can be found on Earth. The study was published in a scientific journal.
