The geochemical cycle

The geochemical cycle describes how elements and minerals move through the Earth's crust, surface, and atmosphere over time. These cycles involve processes like weathering, where rocks break down; erosion, which transports materials; and volcanic activity, which redistributes elements from deep inside the Earth. Elements such as carbon, nitrogen, and phosphorus are essential for life, and they circulate through the environment by cycling between rocks, water, soil, and living organisms. This continuous movement helps maintain a balance, supporting ecosystems and influencing the planet’s climate and geology.
