Flashcards in 2B.2 Deck (12)
How are haff coasts formed?
parallel - concordant
low energy - deposition by onshore winds
long sediment ridges + sand
These build up creating lagoons (haffs)
EG SOUTH COAST BALTIC SEA
How are dalmatian coasts formed?
Tectonic activity folds limestone layers forming anticlines and synclines that are parallel
Sea level increase due to ice age
Raised anticlines are up.
How are coves formed?
h.a and abrasion
EG Purbeck and Portland
bands of rock on Concordant coastline
How are headlands formed?
include - PERPENDICULAR, SWANAGE BAY, DIFFERENTIAL EROSION, wave refraction
Example of a concordant and discordant coast?
The Isle Of Purbeck on the southern coast has concordant on the eastern coast it is discordant.
What is geological structure?
how the rock is formed
What are the 3 sizes?
What is a concordant coastline?
rock parallel to coastlines eg coves
What is a discordant coastline?
rock perpendicular to coastline eg more headlands and bays
What is coastal morphology?
study of the origin and evolution of coastal features
What does unconsolidated mean?
loosely arranged easy to take apart
