Question

The is the main regulator of CO2 in the atmosphere, because it covers most of the Earth, and CO2 dissolves easily in it.

Answer 1

The main regulator of CO2 in the atmosphere is the **ocean**. The vast surface area of the oceans allows them to absorb a significant amount of atmospheric carbon dioxide. When CO2 is dissolved in seawater, it forms carbonic acid, which plays a key role in regulating the levels of CO2 and maintaining the Earth's carbon cycle. This interaction between the atmosphere and the oceans helps to moderate climate and control global temperatures. Additionally, the oceans support various biological processes, including photosynthesis by marine plants, which further influences atmospheric CO2 levels.
