Sea stacks are geological formations that occur when erosion from waves and weathering gradually wears away the softer rock surrounding a more resistant rock formation, leaving isolated columns or pillars of rock standing in the sea. These structures typically form along Coastlines and can vary in height and shape. Sea stacks are often seen as dramatic natural landmarks and are indicators of coastal erosion processes. They can also provide unique habitats for various marine and bird species.
Sea stacks are formed when a sea arch collapses and sea arches are formed when waves (pound) erode or ware away a whole in the headland.
sea caves are turned into stacks because of the erosion and deposition of the sea waves gives rise to coastal land forms.

By erosion. Sea caves erode to become sea arches which erode to form sea stacks.
Rocks surrounded by sea are called sea stacks or coastal stacks. These are isolated pillars of rock that have been eroded by the sea over time, often standing off the coast or in the water.
The sea first forms sea caves then sea arches then sea stacks and finally it forms sea stumps which will eventually disappear.
Coastal erosion, usually due to wave action and weathering processes, causes sea stacks. As waves erode the coastline, softer rock is worn away more quickly, leaving behind more resistant rock formations like sea stacks. Over time, the repeated cycle of erosion and reduction in size of headlands or cliffs results in the formation of sea stacks along the coast.
Tall narrow columns of rocks along seacoasts are called sea stacks. These formations are created through the erosion of coastal cliffs and the constant battering of waves over time. Sea stacks are usually made of more resistant rock material, standing as isolated pillars along the coastline.
Sea stacks are formed by erosion. They are remnants of headlands or cliffs that have been eroded over time by the sea, leaving behind isolated rock formations. These formations are typically more resistant to erosion than the surrounding rock, resulting in their distinctive shape.
Waves pounding the shoreline can make cracks. The cracks then gradually get larger and turn into a small cave. When the cave wears through the headland, an arch forms. Further erosion causes the arch to collapse, leaving the pillar of hard rock standing away from the coast-the stack. Eventually, erosion will cause the stack to collapse, leaving a stump.
Sea stacks form over a long period of time—thousands or even millions of years.
