CASE STUDY-Saltburn to flambrough head Flashcards
1
Q
main influences on coastline
A
geology and glaciation
2
Q
SALTBURN and SCARBROUGH
A
- upland=400m above sea level (highest cliffs in England)
- rocks=sandstone, shale, ironstone and limestone
- difference in rock hardness is responsible for coastal scenery (headlands and bays)
3
Q
Energy system
A
- dominant waves from N/NE=fetch=>1500km long
- north facing coast=highest energy input
- longshore drift transports sediment along coast
4
Q
Cliff profiles of region
A
- horizontally bedded sedimentary rocks=cliffs along stretch
- cliffs have vertical face
- most cliffs overlaid by thick layer of glaciation till
- Flambrough=mechanically strong and horizontal chalk bed produces vertical face (20-30m high)
5
Q
robin hoods bay coastal plan forms
A
-anchored by more resistant sandstone=headlands
6
Q
filey bay coastal plan forms
A
-flanked by more resistant rock e.g. limestone + chalk
7
Q
flambrough head coastal plan forms
A
-clay rocks crop out N and S-deep bays formed
8
Q
why does area not have spit landforms?
A
- absence of shallow embankments of broad estuaries to act as sediment sinks
- high tidal range (4m)
