Critical Zone
Special | 6m 26sVideo has Closed Captions
Critical Zone scientists work to discover how the Earth's living skin is structured.
The Critical Zone supports terrestrial life on Earth. It is the region above and below the Earth surface, extending from the tops of the trees down through the subsurface to the bottom of the groundwater. It is a living, breathing, constantly evolving boundary layer where rock, soil, water, air, and living organisms interact.
Science Specials is a local public television program presented by WSKG
This project is in partnership with the Paleontological Research Institution and funded by the National Science Foundation.
