Q

What material are the headland and bays at Robin Hood’s Bay?

A

Weak shales
Resistant sandstone

17
Q

What material is Flamborough Head?

A

Chalk with deep bays of clay either side

18
Q

What creates shore platforms?

A

High energy waves causing erosion, cliff retreat and rocky shore platforms

19
Q

What is the slope angle of the Robin Hood’s Bay platform?

A

1 degree

20
Q

How many geos are there?

A

50+ N or NE facing

21
Q

What landforms are there originating from the headlands? (4)

A

Blowholes
Caves and arches
Stacks
Inlets/depressions

22
Q

Where are the best developed beaches along the coastline?

A

Low energy environments of Scarborough and Filey Bay

23
Q

Why do beaches not form successfully? (4)

A

Sand and shingle accumulate very slowly
Low fluvial inputs
Slow erosion of resistant rock
High energy waves move sediment before it can accumulate

24
Q

What sort of features does the coast lack because of the absence of sediment accumulation?

A

Spits and other drift aligned features

25
Q

What is the tidal range?

A

High 4m
