Critical Zone Game

Learn the components of the Earth's Critical Zone!

The Earth's Critical Zone is: the living, breathing, constantly evolving boundary layer where rock, soil, water, air, and living organisms interact. These complex interactions regulate the natural habitat and determine the availability of life-sustaining resources, including our food production and water quality.
