System
Any collection of things that interact with one another.
Subsystem
A system contained in a larger system that supports and interacts with the larger system. Matter (energy) flows into and out of to other parts of the larger system.
Open System
Exchanges both energy and matter with the surrounding environment.
Closed System
Exchanges only energy with the surrounding environment.
Input
The amount of material enetering a system.
Output
The amount of material leaving a system.
Cycle
A system that moves matter and energy from one reservoir (subsystem) to another without leaving the system as the levels of matter and energy remain unchanged.
Boundaries
A physical limit.
Flux
Tells how fast, or the rate that matter enters or leaves a system.
Evapotranspiration
The general process of evaporation and transpiration.
Evaporation
Occurs when water in the liquid phase passes into the gas phase.
Transpiration
Water loss by plants.
Geochemical Cycle
The shortage and movement of a particular chemical. Explains how matter moves beteen reservoirs on Earth.
Reservoir
Any environment in which matter is stored.
Residence Time
The average length of time that matter in a system remains in a given reservoir. Mass(volume)/total flux in (or out).
Characteristics of Systems
Made from individual parts to work as one. Connected to one or more other systems. If a part of the system is missing or damaged, the system won't work.
Importance of inputs and outputs
Moves matter between different reservoirs.
