Systems Flashcards
What are inputs?
Where matter or energy is added to the system
What are outputs?
Where matter or energy leaves the system
What are stores?
Where matter or energy builds up in a system
What are boundaries?
Limits to the system
What are open systems?
When systems receive inputs and transfer outputs of energy or matter with other systems
What are closed systems?
When energy inputs equal outputs
What is dynamic equilibrium?
in a system when inputs equal outputs despite changing conditions
What is positive feedback?
Occurs when a chain of events amplifies the impacts of the original event
What is negative feedback?
Refers to a chain of events nullifies the impacts of the original event, leading to dynamic equilibrium
What are carbon and water cycles on a local scale?
Open systems
What are carbon and water cycles on a global scale?
Closed systems
