The Critical Zone

Summary and Final Tasks


In this second lesson of the biota unit, you considered the complex interrelationship between climate and biota with the landscape and parent material that determine the flow of energy, water, and nutrients in biomes. You also learned that soil and Critical Zone processes can be distinctive to a biome or to a particular region of Earth. You looked at global-scale trends in these relationships and considered the various factors that may describe some of the disparities in these global-scale relationships. You also learned about the primary contributing factors to soil ecology and biodiversity and applied this knowledge to your study site. Finally, you learned where and how to access land cover maps.
