Lesson Details
Key learning points
- Different wave types (constructive and destructive) affect the coast.
- The coast is shaped by processes of erosion (hydraulic power, abrasion and attrition).
- The coast is shaped by transportation (longshore drift) of sediment.
- The coast is shaped by deposition.
Common misconception
Swash is when a wave moves down the beach to the sea and backwash is when a wave moves up the beach from the sea.
The swash is the movement of the wave from the sea to the beach which brings sediment with it. Whereas the backwash is the movement of the wave from the beach to sea.
Keywords
Waves - ripples in the sea caused by wind blowing over the surface of the water
Erosion - the action of water wearing away rocks
Destructive waves - high, steep waves, typically formed by local storms, that remove sediment from beaches
Constructive waves - low waves, typically formed by distant storms, that deposit sediment onto beaches
