Scientists at NSF's network of nine Critical Zone Observatories (CZOs) are addressing questions about the thin veneer of Earth's surface that extends from the top of the tree canopy to the base of weathered bedrock. The zone is critical because it's where fresh water flows, soil is formed and life flourishes. The critical zone provides most of the ecosystem services on which society depends.
