sea level change landforms Flashcards
emergent coastlines
sea level fall causes landforms to emerge
raised beaches (emergent)
e.g. Isle of Arran, Scotland
sea level drops, beach sediment becomes vegetated and becomes soil
shows wave cut notches, arches, stacks on land
submergent coastlines
sea level rise causes sea to submerge existing coastline, low-lying land masses are flooded
rias (submergent)
v-shaped, rise in sea level submerges river valley
gentle long- and cross-profile, flatten out as reach the sea
e.g. fowey estuary in cornwall
Dalmatian coasts (submergent)
e.g. Dalmatian coastline in Croatia
valleys flowing parallel to sea causing islands parallel to coastline
fjords (submergent)
u-shaped valley
rise in sea level submerges a glacial valley
very steep sides, very deep valleys
e.g. sogne fjord, norway
