Two possible sources of Earth's oceans are volcanic outgassing and comet impacts. Volcanic outgassing refers to the release of water vapor and other gases from the Earth's interior during volcanic activity, which eventually condensed to form oceans. Additionally, comets and icy bodies from the outer solar system could have collided with Earth, delivering substantial amounts of water in the form of ice.
