WebMay 16, 2024 · Critical zone science provides a novel and unifying framework to consider those coupled interactions that control biogeochemical cycles and fluxes of energy and matter that are critical to sustaining a habitable planet. Biogeochemical processes are at the heart of energy and matter fluxes through ecosystems and watersheds. WebThe “Critical Zone” is the thin layer between the upper surface of unweathered rock and the upper boundary of the vegetation. It is a giant reactor in which rivers and wind continuously move sediment eroded from soils. Yet soils have mantled most of this surface persistently in times before human land use.
