Earth’s geochemical cycles

Earth’s geochemical cycles are natural processes that move vital elements like carbon, water, nitrogen, and minerals through the planet's land, water, and atmosphere. These cycles distribute essential substances, support life, and shape the environment. For example, water cycles through evaporation and rain, nutrients cycle between soil and living organisms, and carbon moves between the atmosphere and oceans. These interconnected processes ensure the stability and sustainability of Earth's ecosystems, maintaining a balance that allows life to thrive over geological time scales.
