What happens where the land meets the sea?
Erosion Processes
Hydraulic action
When the force of waves hit the cliff causing the beds to erode.
Attrition
When the material carried by the waves bump into each other and are broken into smaller pieces.
Abrasion
When the beds are worn down by the waves load.
Corrosion
When the acid in the water slowly dissolves the bed and joints.
Deposition Landforms
salt marsh
beaches
lagoons
spurn head
tombolo
caves
spit
stacks/stumps
bays
Wave types
Constructive wave
Waves when the swash is stronger than the backwash
Destructive wave
Waves when the backwash is stronger than the swash
Coastal Management
Hold the line
Hard Engineering
Hard engineering is a type of coastal management strategy that prevents erosion and flooding by absorbing the energy of waves.
Soft Enginnering
Soft engineering is a method of reducing coastal erosion and river floods by utilising the natural environment.
Do nothing
Weathering
Chemical
When a chemical reaction in a rock causes it to dissolve.
Biological
When rocks disintegrate due to animals
Physical
The breaking of rocks into smaller pieces
Geology
The investigation of the Earth's structure, evolution, and dynamics, as well as its natural mineral and energy resources
Transportation
Saltation
When dissolved minerals are carried by the sea
Suspension
When fine materials such as clay & sediment is carried by the sea
Traction
When large boulders & pebbles are rolled along the sea-bed
Saltation
When tiny stones, pebbles & dirt bounces along the seabed.
