Biogeochemical Cycles
In geography and Earth science, a biogeochemical cycle or the cycling of substances is a pathway by which a chemical substance moves through biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments of Earth. Our standards focus on the carbon, water, phosphorus, and nitrogen cycles.
