geochemical pathways

Geochemical pathways describe how elements and compounds move and transform within Earth's systems. They involve processes like weathering, where rocks break down; transport, where materials are carried by water, wind, or ice; and mineral formation, where substances crystallize out of solutions. These pathways control the distribution, concentration, and cycling of elements such as carbon, iron, and nitrogen in soils, rocks, oceans, and the atmosphere. Understanding geochemical pathways helps us grasp phenomena like nutrient cycling, mineral deposits, and environmental changes, revealing the complex interactions that sustain life and shape our planet.
