Resistant rock coastlines vs coastl plain landscapes Flashcards
What parts of Britain are resistant rock coastlines found in?
Western and Northern Britain
What type of environment are resistant rock coastlines found in?
High energy environments
High energy environments tend to be…
-Stretches of Atlantic falling coasts where the waves are powerful for most of the year
-Where rates of erosion exceed rates of deposition
What landforms occur on resistant rock coastlines?
Headlands, cliffs and shoreline platforms
What are coastal plain landscapes?
Coasts of younger, weaker sedimentary rocks (chalk, clay and sandstone)
Example of coastal plain?
The wash area which has a range of habitats from tidal creeks, mud flats, salt marshes and lagoons
Where are coastal plains found?
Much of Eastern England coast consists of low-lying sandy beaches such as the one in Bambrugh, Norfolk
What are the factors affecting erosion rates?
-High energy waves
-Absence of a beach
-Rising sea levels
-Coastal management
What are usually found in low energy coastlines?
Sandy and estuarine coasts
At low energy environments…
The rate of deposition exceeds the rate of erosion
Low energy environments in the Uk tend to be…
Stretches of the coast where the waves are less powerful or where the coast is sheltered from large waves (Lincolnshire and Norfolk)
