The Slow Biogeochemical Cycle

The slow biogeochemical cycle involves the gradual movement of elements like carbon, nitrogen, and phosphorus through Earth's land, water, and atmosphere over extended periods—sometimes thousands to millions of years. These cycles include processes like rock weathering, mineral formation, and the burial of organic matter, which release or store nutrients and gases slowly. This long-term cycling helps regulate Earth's climate, maintain soil fertility, and support ecosystems. Unlike rapid biological processes, these slow cycles set the foundation for sustainable life by controlling the availability of vital elements over geological timescales.
