See pg. 5 Earth Systems Concepts Systems analysis- method for understanding operational behavior in many disciplines Systems Theory System- ordered, interrelated set of things & thr attributes, linked by flows of energy/matter, as distinct fr surrounding envt outside the sys; elements w/in it may be arranged in a series/interwoven...
