Depositional Landforms Flashcards
Formation of spits
LSD carries material west to east
Where the coastline changes to north to south, there is a build up of sand and shingle. Material builds eastwards to form a spit. Refraction carries material to sheltered water to form a curve in the spit
Formation of tombolo
A spit that joins onto an island to the mainland
Formation of bars
If a spit develops across a bay and there’s no strong flow of water from the landward side, a bar is formed
Formation of beaches
Formed by the accumulation of sand and shingle deposited between high and low tides
Offshore bar
A ridge of material, semi submerged seawards of the refer zone
Barrier beach
A bank of material parallel to the coast, not submerged by tides
Headlands and Bays
Areas with discordant rock, destructive waves attack lines of weakness and are more prone to the forces of erosion NOT FINISHED
