- morphology
- discordant coast
- boulder clay - rest of cliff
- chalk - flamborogh head
- Geology
- boulder clay - porous and permeable
- deposition from melting glaciers
- Holderness Coast
- Coastal landforms
- headland - flamborough head
- bay - mappleton/ hornsea
- spit - spurn head
- Coastal erosion
- sub-arieal
- freeze-thaw
- wetting and drying - boulder clay (expand when wet and contract when dry causing them to break)
- chemical weathering - ineffective as only works on chalk (flaborough head)
- sub-arieal
- fastest eroding coastline in EU

- sub-arieal
- mass movment
- slumping (boulder clay) - sub-arieal produces cracks.
- rain percolates cliff making it heavier and lubricated
- weakened cliff cant hold extra weight and slides
- slumped material collects at cliff base, removed by sea, cliff libe retreates

- low pressure weather systems pass over North Sea - strong winds,waves,high tides
- exposed to winds and waves from NE
- small fetch 500-800km high energy
- exposed to winds and waves from NE
- sea floor - deep
- waves reach cliffs without being weakened by friction of shallow beaches
