The Critical Zone

Summary and Final Tasks


This lesson briefly touched on the complexity of life on Earth and the interactions between organisms and their environment. It is important to recognize that the Critical Zone is so named because it is this thin veneer at Earth's surface that supports life on our planet—yet life also plays a complex and vital role in shaping and sustaining the zone. In the next lesson, we will study in more detail the complexities of various biomes and ecosystems and their role in CZ function. We will also evaluate the relationship between biomes and soils, and learn how to make site-specific determinations of landscape types.
