Question

How the water formed on earth? Prove it with proof? I will mark the answer i like as brain list answer

Answer 1

The origin of water on Earth, or the reason that there is clearly more liquid water on Earththan on the other rocky planets of the Solar System, is not completely understood. There exist numerous more or less mutually compatible hypotheses as to how water may have accumulated on Earth's surface over the past 4.5 billion years in sufficient quantity to form oceans.

Possible sourcesEdit

Internal sourcesEdit

Gradual "dehydration melting"—leakage of water stored in hydrate minerals of Earth's rocks—could have formed a portion of its water.[2][3][4] Water may also have come from volcanism: water vapor in the atmosphere that originated in volcanic eruptions may have condensed to form rain, slowly filling Earth's oceanic basins.[5][not in citation given]
