Geography- Erosion + Deposition Flashcards
definition for hydraulic action
When the force of the wave erodes the coast as they crash against it
Definition of abrasion
when eroded material in waves crashes against the coastline
solution definition
When the seas load is dissolved by water
Compressed air definition
Created when a wave crashes against the joints and cracks in the coastline
erosion and coastline definition
Certain sections of Ireland coastline are more vulnerable to wave erosion, as there are composed of softer sedimentary rock type such as lime or shale
Bay definition
A large eroded area that has filled up with water, surrounded by resistant rock from the headland
The headland definition
Land made of hard rock that is more resistant to erosion which extends I went to the sea
geo definition
A gap in the headland wear a blow hole and a cave once existed
sea arch definition
A gap that forms when a cave fully eroded through a headland
Seacliff definition
A high , steep feature made of rock and soil that has been eroded back by the sea
Blowhole definition
Forms when the roof of a cave is eroded vertically
wave cut platform definition
A sloping floor of rock extending from the shore out to sea
Sea cave definition
an opening made when weaker rock is eroded at the base of seacliffs or headlands
Sea stack definition
A piece of rock that stands alone in coastal water
Stump definition
A sea stack that has been worn down by the forces of a erosion
definition of transportation
Transportation refers to the movement of eroded material by the sea
Longshore drift definition
longshore drift is the transportation of material up and down the coast in a zigzag pattern
Deposition definition
deposition refers when the sea drops or deposits its load of eroded material along the coast by the swash of waves
Three landforms of marine deposition
Beach and sand dunes
sand Spit and lagoon
Tombolo spit
Three examples of ways people use the sea
food supply
Transport
Recreation
