What is considered the largest carbon reservoir? (2 points) Rocks and sediment Terrestrial biosphere Fossil fuels

Rocks and sediment are actually the largest carbon reservoir on Earth, containing about 99% of the carbon stored in the planet. This enormous store includes limestone, coal, and other geological formations that have trapped carbon over millions of years, playing a crucial role in the long-term carbon cycle. Fossil fuels, such as coal, oil, and natural gas, are also significant carbon reservoirs, as they store carbon that has been trapped during the decomposition of ancient organic matter. When extracted and burned, these fuels release carbon dioxide into the atmosphere, which dramatically impacts climate change and global warming. Understanding both reservoirs helps us recognize the importance of sustainable energy practices.
