Geological carbon cycle

The geological carbon cycle refers to the long-term movement of carbon through Earth's systems over millions of years. Carbon exists in rocks, soil, oceans, and the atmosphere. It moves through processes like volcanic eruptions, which release carbon dioxide (CO2), and weathering of rocks, which can store carbon. Plants absorb CO2 for photosynthesis and, when they die, some carbon is stored in sediments. This cycle regulates the Earth's climate and supports life. Understanding it helps us analyze past climate changes and predict future ones, especially in the context of current climate challenges.
