The critical zone is the life-sustaining part of the Earth's System, extending from the tops of the trees down to the bedrock below. It encompasses the zone where rock, soil, water, air, and living organisms interact and is critical for supporting life on Earth. The stratosphere and troposphere are both parts of the atmosphere, which is a component of the Earth System, but not specifically the life-sustaining part.
