For a significant period, scientific consensus said that Earth’s water was not indigenous to its segment of the protoplanetary disk. The prevailing theory suggested that water and other substances must have been transported to Earth from the Solar System’s outer reaches at a later developmental stage. Contemporary studies, however, point towards the presence of hydrogen within Earth as a contributing factor in the genesis of its oceans. It’s worth noting that these hypotheses are consistent. Compelling evidence also supports the notion that Earth’s water inventory was augmented through celestial collisions with icy planetesimals, whose composition resembles asteroids at the outer periphery of the asteroid belt.
The origin of water on Earth is believed to be from a combination of sources. One theory suggests that water was brought to our planet by comets and asteroids during the early stages of its formation. Another theory proposes that water was formed through chemical reactions in the Earth’s interior and released through volcanic activity. Additionally, water vapor was likely present in the atmosphere, which condensed and fell as rain, eventually forming oceans. The exact contribution of each source is still a topic of scientific investigation.
