When the atmosphere has too much carbon dioxide in it the oceans absorb some if it to achieve a new balance which is an example of what?

When the atmosphere has excess carbon dioxide, the oceans absorb it in a process known as carbon sequestration. This is an example of a natural feedback mechanism, where the Earth's systems work to achieve a new equilibrium. However, this absorption can lead to ocean acidification, which negatively impacts marine life and ecosystems.
