Origin and development of landforms of coastal deposition
Terms in this set (12)
An elongated narrow ridge of land that has one end joined to the mainland and projects out onto the sea or across an estuary.
A spit that joins an island to the mainland.
A spit that develops across a bay where there is no strong flow of water so the sediment is able to reach the other side.
An elongated bank of deposited sand or shingle lying parallel to the coastline and is not submerged by incoming tides; the bank is high enough to allow sand dunes to develop.
Simple spit features
Are either straight or recurved -Do not have minor spits or recurved ridges along their landward edge.
Compound spit features
May have similar features to simple spits -Have a number of recurved ridges or minor spits along their landward side.
An accumulation of sand shaped into mounds by the wind.
A ridge of beach material that remains semi-submerged accumulates seaward of the breaker zone.
The point where the land meets the sea and represents the accumulation of sediment deposited between low spring tides and the highest point reaches by storm waves.
Longshore drift moves sediment across the coastline which then forms a spit when the sediment is deposited. Overtime a hook can develop if the wind directions changes, waves cannot get passed a spit which creates a sheltered area where silt can accumulate and form a mudflat.
A beach ridge that is built up by constructive waves.
Semi-circular shaped depressions which form when the waves break directly onto the beach and swash and backwash are strong. They usually occur at the junction of the shingle and sandy beaches.
