Length of East Yorkshire coastline
From where to where?
60km from Saltburn to Flamborough Head
2 of 35
Fetch
1500km
3 of 35
Discordant or concordant?
Discordant coastline (therefore prominent headlands and bays can form
4 of 35
Direction of Strata bedding
Primarily horizontally bedded strata
5 of 35
Sediment sources
Offshore (brought onshore during the Flandrian Transgression)
Terrestrial (from the cliffs)
Fluvial (limited amount from the River Esk at Whitby due to human activity)
6 of 35
What makes the cliffs have a gentle slope?
Glacial tilt which covers most of the coastline and is less resistant rock, therefore weathered easily
7 of 35
Direction of movement of sediment by long-shore drift
Based on current rates of erosion, possibly within the last 6000 years

Example of a shore platform on the East Yorkshire coastline
Robin Hood's Bay
13 of 35
Cliffs on the East Yorkshire coastline
Flamborough is made of chalk (high resistivity) so cliffs are 20-30m high at an angle of 40˚
At Robin Hood's Bay and Saltburn, cliffs are taller but stepped due to varying geology
14 of 35
Why are there very few beaches on the East Yorkshire coastline?
Low fluvial sediment
Slow rates of erosion
Removal of sediment due to high energy waves
15 of 35
Why are there no spits?
High tidal range (approx 4m)
No estuaries or calm areas

Differing geology to form Flamborough Head
Flamborough = chalk
Bays either side = clay
18 of 35
Differing geology to form Robin Hood's Bay
Robin Hood's Bay = weak shale
Ness Point/Ravenscar = sandstone

Name of spit between Petit and Grande Rhone
When and how it formed
Beauduc Spit
Formed at the start of the 18th century, when a large flood moved sediment down to the mouth
25 of 35
Length of the delta
90km
26 of 35
Shape
Lobate delta
(braided delta)
27 of 35
Dominant energy
Wave energy is dominant over fluvial
