Coastal System

3. carries sediment back down the beach at right angles to the shoreline
4. sand dunes, salt marshes and mangroves
8. area lying between the high water mark and low water mark. Inter-tidal or surf zone
9. wave action, tidal movement, erosion, weathering, transportation, deposition
11. area between low water mark and the point where waves cease to have any influence on the land beneath them (breaker zone)
12. distant over sea that wind blows to generate waves

1. sediment washed out to sea or deposited further along the coast
2. the area beyond the point where waves cease to impact upon the sea bed and in which activity is limited to deposition of sediments
3. area between the high water mark and landward limit of marine activity usually above the influence of waves
5. range/difference between high tide and low tide level
6. lateral transfer of sediment along a stretch of coastline in a series of 'zig zags'
7. river sediment, sediment from cliffs that have been eroded or suffered landslides, and sediment that has been transported by waves from offshore
10. carries sediment up the beach, parallel to the prevailing wind
