Question

the main regulator of CO2 in the atmosphere, because it covers most of the Earth, and CO2 dissolves easily in it. Millions of years ago, huge deposits of carbon were stored, which were formed from dead plants and other organisms.

The main regulator of CO2 in the atmosphere is the ocean, as it covers approximately 71% of the Earth's surface and can absorb large amounts of carbon dioxide. When CO2 enters the ocean, it dissolves in seawater, where it can participate in various chemical reactions, forming carbonates and bicarbonates, which play a vital role in the ocean's carbon cycle.

Additionally, millions of years ago, significant deposits of carbon were formed from the remains of dead plants and other organic matter. These deposits eventually transformed into fossil fuels, such as coal, oil, and natural gas, through geologic processes. The combustion of these fossil fuels releases stored carbon back into the atmosphere as CO2, contributing to the greenhouse effect and climate change. Thus, the relationship between the ocean and atmospheric CO2 is critical for understanding global carbon cycles and the potential impacts of human activities on climate.
