Best Answer

The cliff face is eroded by hydraulic action, which over time forms a cave. The back and roof of the cave is then eroded until it breaks through the headland forming an arch. Further erosion on the arch causes it to collapse, thus forming the stack. More erosion on the stack will cause it to form a stump.

Geological stacks are formed through a combination of erosion and weathering processes, typically in coastal areas. They are created when softer rock erodes away faster than harder rock, leaving behind a tall vertical column of harder rock. Over time, continued erosion can cause the stack to become isolated from the mainland.
