Web the region of the protoplanetary disk closest to the sun was very hot early in the history of the solar system, and it is not feasible that oceans of water condensed with the earth. Another idea is that ocean water came from deep inside the earth. Photosynthesis caused the amount of carbon dioxide to. Water vapour condensed to form the oceans. The lighter rock rose and.

A new study may explain how earth got its oceans. Web when the surface of earth had cooled to below 100 °c (212 °f), the hot water vapour in the atmosphere would have condensed to form the early oceans. It was brought to the surface. That’s in part because the planet was too hot for water to. Contributions from asteroids other events were occurring on. Web the first oceans could have formed as early as 4.2 to 4.4 billion years ago! Web after the earth's surface had cooled to a temperature below the boiling point of water, rain began to fall—and continued to fall for centuries. Web ocean formationafter earth began to form about 4.6 billion years ago, it gradually separated into layers of lighter and heavier rock.
