- a headland contains small cracks in the clifface
- hydraulic action causes the crack to enlarge and become more suseptible to other types of erosion such as abraision
- this constant erosion will go on for a long time until it forns a cave
- the headland will have caves on both sides and they will erode inwards toward each other until they breack through forming an arch
- erosion will continue to happen of the base of the arch causing continuous rock falls until the sides can't support the roof and it will collapse forming a stack
- the base of the stack will continue to be eroded until it can't support it's own weight and collapses forming a stump away from the headland
