Erosion Processes
Hydraulic the wearingforce rocks
There are-wheremain typesofofandtothey hitrock by air into
erosion fragments
Attrition - -Action-mineralsof rocks as broken againstthe
Abrasion- the breakdownforce of waterrockin the Coast.
Scouring occurs the
Solution four where rock waves dissolved
Wave Pounding -sheerof waterdue arecompressing each

hitting rocks
cracks
other in the rock, in the the base of it repeats until the
being hurled against cliffswater. andcliffs
fragments swirl around at
salt and chemicals cracks expand
rock is eroded
Erosion Landforms
Formation of Wave-cut Platform

All the erosion processes apply to forming a
Wave cut platform.
Examples of wave cut platform
