Coastal Landforms
- Bays - soft rock erodes quicker causing an inlet on the coast
- Headland - hard rock erodes slowly so it's left
- Wave Cut Platform - constant tide erodes the headland away leaving an indent
- Sea attacks base = wave cut notch
- Cliff collapses = wave cut platform
- Cliff retreats
- Cave, arch, stack, stump
- Destructive waves hit the headland causing the rocks to erode away, forming a cave
- Other processes happen and cause the cave to widen over time, forming an arch
- Waves hit the arch and small pieces of the rocks hit it causing cracks to form
- Gravity acts on the arch and it falls away, forming a stack
- Overtime, the stack erodes away leaving a stump
- Beaches - Made of eroded material that has been transported and deposited
- Spits
- Sediment is carried by longshore drift
- Where there's a change in shape, deposition happens, forming the spit
- Bars - a spit that's grown across the bay, joining to two headlands
