Which reservoir has the largest deposit of carbon? (1 point) oceans rocks and sediment atmosphere plant biomass

Did you know that oceans are the largest reservoir of carbon on our planet? They hold about 38,000 gigatons of carbon, far more than the atmosphere, rocks, or even plant biomass! This vast carbon sink plays a crucial role in regulating our climate by absorbing carbon dioxide from the atmosphere. Another fascinating fact is about the carbon found in rocks and sediments. While they contain a significant amount of carbon—around 100,000 gigatons—this carbon is mostly locked away in geological formations and takes millions of years to cycle back into the atmosphere, making rocks a long-term carbon reservoir. Talk about a slow and steady game in the carbon cycle!
