Besides the origin of life, what atmospheric change was linked with ocean formation?

Correct answer: Some gases dissolved in water and changed atmospheric proportions

The formation of oceans altered the relationship between the atmosphere, the surface and chemical processes on Earth. Once liquid water accumulated, soluble gases such as carbon dioxide could dissolve in it and take part in chemical reactions. This reduced or changed the proportions of certain gases in the atmosphere and contributed to the gradual development of a more stable atmospheric environment. Ocean formation therefore had consequences beyond providing a possible habitat for early life. The first atmosphere was not simply created by solar wind, the core did not become gaseous, and a complete ozone layer did not exist at that early stage. Hence, option A is the scientifically appropriate answer.
