proses of costal erosion
-
-
compressed air = air in the rocks gets compressed by incoming waves when the water moves out and the air expands causing the rocks to shatter over time
-
-
landforms of sea erosion
head lands and bays : the soft rock gets eroded in-between to hard rocks this is known as differential
soft rock like lime and sand stone
sea cliffs : the waves erode a notch at the base of the cliff the notch then becomes large enough that it collapses under its own weight
blow hole : is a passage that goes' through the roof of a cave to the land surface above it is formed when powerful waves compress air that breaks a hole true the roof

managing the sea Groynes they are concreat or wooden walls or fenses that are bilt out at right angls to the cost they reduse long shure drift by trapping the sand and sedament
sea walls are bilt to break the power of the incoming waves they are coorved at the top to push the waves back to sea
gabions ions they are steal wire cages that are filled with stone they slow down or prevent arotion by breaking the power of the waves

long shore drift the waves aproch the sure from the side the swash pushes the water up the beach by the incoming waves then the back wash that drages the matereal down further from the sea and the proses rapeats itself in a zig zag pattern
depositon of the sea this occors when the power of the waves is redused and the sea will drop its load and this is becos it uses energy
