ES0103  Earth System Processes

The interactions you've been describing are the processes of Earth system science. The current "balance" among these complex interactions makes it possible for life to flourish here. Because the spheres are all part of the same interconnected system, changes in any sphere ultimately affect the other spheres as well.
