Flamborough Head Flashcards
what is the main rock composition of Flamborough Head
sandstones, shales and limestones but also chalk
what is the fetch of Flamborough Head
large -> 1500km
what is the erosion rate of weak clay at Flamborough Head
0.8m / year
what is the erosion rate of resistant sandstones and limestones at Flamborough Head
0.1m / year
where is an example of a bay at Flamborough Head
Filey Bay
where is an example of a shore platform at Flamborough Head
Robin Hoods Bay
where is an example of stacks and geos at Flamborough Head
Green Stacks Pinnacle
what’s an example of a geo at Flamborough Head
Huntsman Leap
what height do waves peak at along the Flamborough Head coastline
4m
what direction does LSD move at Flamborough Head
North to South
what are different examples of inter-relations at Flamborough Head
- headland and bay - Filey Brigg and Filey Bay
- rivers and landforms - River Esk and Robbin Hoods Bay
- sediment supply from North to South through LSD - from Saltburn to Filey Bay and Selwicks Bay
- wave cut platform and cliffs - Robbin Hoods Bay - when long enough it can stop erosion - flat (around 3 degrees) but more effective at low tide than high
where is the coastline concordant at the high energy case study
Saltburn
how does the landscape system change over time at Flamborough Head in the short term
- cliff collapse but caused by long term erosion
seasonal
- increased precipitation = increased river sediment in winter
- beach profile grows in summer = wider and higher
- more storms = wind and wave energy increase in winter
how has the landscape system change over time at Flamborough Head in the long term
- offshore sediment brought up over 9000 years ( Flandrian Transgression)
- wave cut platforms - eroded over millennia
- sediment from Jurassic Period
- end of glacial maximum ( 15,000 years ago) - till deposited on coastline
- erosion of arch - stack - stump as chalk 0.1m/y
