A system consists of  inputs  (entering the system),  flows  or transfers (movement through the system), stores  (storage within the system) and  outputs  (leaving the system).

Our focus:  How does precipitation make its way to streams, rivers and lakes?  What happen  to the precipitation that finds its way to these water bodies?

Scene 10

It is  part of  the hydrological cycle which operates on the land. A system consists of  inputs  (entering the system),  flows  or transfers (movement through the system),  stores  (storage within the system) and  outputs  (leaving the system).
