Geochemical cycling

Geochemical cycling refers to the natural recycling of elements and compounds through the Earth's systems, including the atmosphere, biosphere, hydrosphere, and geosphere. Elements like carbon, nitrogen, and phosphorus move between land, water, and air, driven by processes such as evaporation, plant uptake, and decomposition. These cycles are essential for maintaining the balance of ecosystems, supporting life, and regulating climate. Understanding these cycles helps us appreciate how different components of the environment interact and the impact of human activities on natural processes.
