PROCESSES THAT GIVE RISE TO COASTAL LANDFORMS
Wave characteristics:
- Fetch-length of time and distance over which wave was been blowing
- swash- friction with sea-bed in shallower water causes waves to break and run up the beach until they lose energy
- backwash- swash water runs back down beach due to gravity.
Marine:
- longshore drift- once rocks and sand are detached from the cliff, waves can move them over coastline. Larger heavier materials will be deposited as waves lose energy.
- wave deposition- waves carry materials up beach, lose energy, and drop them.
Sub Ariel:
- weathering- rocks break down due to freeze-thaw, salt crystals, acid rain and vegetation roots.
- mass movement
LANDFORMS:
erosional:
- headlands-
- formed by continual erosion of…
