Earth critical zone and eco-geochemistry
Earth's critical zone is the “heterogeneous, near surface environment in which complex interactions involving rock, soil, water, air, and living organisms regulate the natural habitat and determine the availability of life-sustaining resources” (National Research Council, 2001). The Critical Zone, surface and near-surface environment, sustains nearly all terrestrial life. WebCritical zones and watersheds are “human habitats”, important for sustaining basic human needs such as water, food, and energy as well as providing crucial …
