Coastal Systems Quiz

What are the inputs in a coastal landscape system?

• Marine and wind erosion

• Fluvial sediment from a river

• Evaporation

• Beach and nearshore sediment accumulations

What are the outputs in a coastal landscape system?

• Kinetic energy from wind and waves

• Thermal energy from the heat of the Sun

• Material from marine deposition, weathering, and mass movement

• Evaporation

What are the throughputs in a coastal landscape system?

• Marine and wind erosion

• Movement of sediment along a beach by longshore drift

• Fluvial sediment from a river

• Evaporation

What is dynamic equilibrium in a coastal landscape system?

• The system produces its own response to a disturbance to bring it back to a state of equilibrium

• The system undergoes self-regulation and changes its form to restore equilibrium

• The system transfers energy and matter from neighbouring systems

• The system is an open system

What is an example of negative feedback in a coastal landscape system?

• The effect of something will initiate a series of self-amplifying events

• Snowball effect, as a snowball starts to roll downhill it picks up more snow and gets bigger, heavier, and faster

• The system undergoes self-regulation and changes its form to restore equilibrium

• The system transfers energy and matter from neighbouring systems

What initiates a series of self-amplifying events in a coastal landscape system?

• Marine and wind erosion

• Fluvial sediment from a river

• Evaporation

• The effect of something

What is the role of fluvial sediment from a river in a coastal landscape system?

• It initiates a series of self-amplifying events

• It transfers energy and matter from neighbouring systems

• It deposits its load at the mouth when available energy decreases

• It is an input to the system

What is the role of marine and wind erosion in a coastal landscape system?

• It initiates a series of self-amplifying events

• It transfers energy and matter from neighbouring systems

• It deposits its load at the mouth when available energy decreases

• It is an output of the system

What is the role of beach and nearshore sediment accumulations in a coastal landscape system?

• It initiates a series of self-amplifying events

• It transfers energy and matter from neighbouring systems

• It deposits its load at the mouth when available energy decreases

• It is a throughput of the system
