Coastal Systems Flashcards
1
Q
Flow/Transfer
A
Form of linkage between one store
2
Q
Closed systems
A
Have transfers of energy both into and beyond the system boundary. Not the transfer of matter
3
Q
Open systems
A
Where matter and energy can be transferred from the boundary into surrounding environment
4
Q
Positive feedback
A
The effects of an action are amplified or multiplied by a subsequent knock-on or secondary effect
5
Q
Negative feedback
A
The effects of an action are nullified by its subsequent knock-on effect
