Coastal systems and Landscapes (Processes) Flashcards
To be able to recite all definitions correctly
What is the definition of an Input?
Material or energy moving into the system from the outside.
What is the definition of an output?
Material or energy moving from the system to the outside.
What is the definition of energy?
Power or a driving force.
What is the definition of stores/components?
The individual elements or part of a system.
What is the definition of flows/transfers?
The links or relationships between the components.
What is the definition of positive feedback?
Where a flow/transfer leads to an increase or growth
What is the definition of negative feedback?
Where a flow/transfer leads to a decrease or decline
What is the definition of dynamic equilibrium?
This represents a state of balance within a constantly changing system.
Give a coastal example of input.
Precipitation, wind
Give a coastal example of an output.
Ocean currents, rip tides, sediment transfer, evaporation
Give a coastal example of energy
Energy associated with flowing water( wind energy transferred to wave energy
Give a coastal example of a store/component
Beach, sand dunes, nearshore drifts
Give a coastal example of a flow/transfer
Wind-blown sand, mass movement processes, longshore drift.
The coast is an open system with links to what other natural systems?
Atmospheric systems
oceanic systems
ecosystems
