Set of interrelated components working together towards some kind of process.
System where there are both inputs and outputs.
The addition of matter and/or energy into a system.
Parts of a system.
A part of the system where energy/mass is stored or transformed.
A form of linkage between one store/component and another that involves movement of energy or mass.
The removal of matter and/or energy from a system.
Lack of change in a system as inputs and outputs remain in balance.
Involves a coupled system that collectively acts to accelerate or decelerate an initial change.
The part of the beach lying between the foreshore and coastline.
The part of the beach which is wet due to the varying tide and wave run-up under normal conditions.
The area between the low water mark and the point where the waves cease to have any influence on the land around them.
The area beyond the point where waves cease to impact the seabed and in which activity is limited to the deposition of sediments.
The zone of wave action on the beach, which moves as water levels vary, extending from the limit of run-down to the limit of run-up.
The region of breaking waves.
The wearing away of the Earth's surface by the mechanical action of processes of glaciers, wind, rivers, marine, waves and wind.
Refers to the distance of open water over which a wind blows uninterrupted by major land obstacles.
The movement of material downhill under gravity, but may also be assisted by rainfall.
The breakdown of rock on or near the earth's surface creating regolith that remains in situ until it is moved by latter erosional processes.
Winds that blow from a single direction over a specific areas of the Earth.
Where material carried by moving water or wind hits exposed rock surfaces, thus wearing them away.
The difference between the elevations of a crest and a neighbouring trough.
The horizontal distance between two crests or troughs.
The number or crests or troughs passing a stationary point per second.
The rush of water up the beach after a wave breaks.
Longshore current/ littoral drift
Where waves approach the shore at an angle and swash and backwash then transport material along the coast in the direction of the prevailing wind and waves.
Strong flow of water running from a beach back to the open ocean, sea or lake.
Process in which deep, cold water rises towards the surface - typically rich in nutrients.
When waves approach a coastline that is not a regular shape, they are refracted and become increasingly parallel to the coastline. Concentrates wave energy on the headland, causing greater erosion.
