Concepts and processes Flashcards
1
Q
System
A
Interconnecting network of Inputs, outputs, stores, flows and boundaries
2
Q
Input
A
Matter or energy added
e.g. precipitation
3
Q
Output
A
Where matter or energy leaves
e.g. evapotranspiration
4
Q
Stores
A
Matter and/or energy builds up
e.g. cryosphere
5
Q
Flows
A
Movement of energy and mass
e.g. between stores
6
Q
Open systems
A
allows the movement of inputs and outputs of both mass and energy across the boundary
7
Q
Closed system
A
Movement of energy across the boundary but not of mass
8
Q
Isolated
A
No movement of energy or mass across the boundaries
9
Q
Feedback
A
Positive - chain of events that amplify the impacts of original event
Negative - chain of events that nullifies the impacts of the original event
