costal landscape system

What is a system

A process with inputs and outputs

Why and what type of system is the coast

Coast is an open system with energy and sediment being beensferred in and out

Types on inputs (energy)

Energy and sediment

Inputs (energy)

• Solar/ sun - thermal energy

• Wind - kinetic energy

• Waves - kinetic energy

• Tides - gravitational energy

• Ocean currents - kinetic energy

• Slope/relief Positions of material an slope

Inputs (sediments)

• Weathering

• Mass movement

• material from offshore/marine deposition (materials dropping of from end of river

• fluvial (River depostion)

• Geology

• Artificial sources

What do input in geography mean?

Inputs are how things enter the system

Stores in costal system

Erosional and deposition

Stores (erosional landforms)

• Headlands

• cliffs

• wave cut platform

• came, arch, stack, stumps

• geos and blowholes

• estuaries

• Outputs (costal)

• Sediment removed (transported) by marine erosion - kinetic energy

• sediment removed by aeolian (wind erosion) - kinetic energy

• Evaporation - thermal energy

What is equilibrium (geography coast)

Where inputs and outputs are equal to eachother

-landscape don’t change

What is Meta-stable equilibrium

Where a system change dramatically between one state and another after the influence of a trigger (accident)
