Document Summary
Planet has a variety of complex interlinked systems. Interaction of beings with surroundings and natural world. Parts interact with each other and through that interaction they influence each other. (cid:1) (cid:1) (cid:1) Systems are defined as or graphed as boxes and arrows. Boxes for the hydrologic cycle show the pools or storage for which water is stored. Water is in the atmosphere, oceans and groundwater or reservoir. (cid:1) Fluxes are the movement of elements and the rate of movement between systems. (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) There may be regional discrepancies but globally they will have to balance out for eg drought somewhere means increase in water else where. (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) Box and arrow diagrams are used to predict and show changes. Flux rate into a pool > flux rate out = pool will grow. More going in than coming out means that the pool will grow.
