holderness coast Flashcards
What’s the Holderness coast made of, and how does that affect erosion?
Mostly soft clay, eroding easily; harder chalk at Flamborough Head resists erosion.
What causes erosion there?
Powerful North Sea waves, especially during storms.
What’s a major natural process affecting the coast?
Coastal erosion and cliff slumping
How does sediment move along the coast?
Waves carry eroded material south, depositing it at places like Spurn Head.
How have humans tried to manage the coast?
Using sea defenses like rip-rap and groynes
What’s a downside of these defenses?
They can stop sediment movement, increasing erosion elsewhere.
: How quickly is the coastline disappearing in some places?
About 2 meters per year.
How has human activity changed the landscape?
Loss of land and settlements to the sea.
How do natural and human actions interact?
Sea defenses slow erosion in one spot, but can speed it up in another.
