Document Summary
Systems: the planet"s env consists of complex network of interlinked systems ex: ecological webs, interaction of living species with surrounding landscapes, biogeochemical cycles, network of relationships among parts that interact and influence one another. There are parts in that system that influence and interact with each other. Earth systems are usually: cyclic; goes through a cycle, hierarchical, w. o human interference systems balance (but with regional/local disparities in time and space) Box and arrow diagrams are used to understand and predict system change. If flux rate (arrows) into the pool exceeds the flux out the pool grows. If more water goes into the water than coming out of the ocean, then your box (the pool of storage) will shrink. If u have less water than your box and more if coming then your box will grow. Flux in + flux out =steady state. We now have an element of predictability.
