What is the difference between a sea stack and a sea stump?
Over many more generations, this arch also falls away, separating one part of the rock from the original cliff. This is your sea stack. Over time, this too gets broken down, causing the stack to collapse, leaving what’s known as a sea stump.

What are sea stumps?
Sea Stump. A sea stump is formed when a tall sea stack is eroded and worn down until it juts just above the surface of the sea.
Why are sea stacks important?
Stacks can provide important nesting locations for seabirds, and many are popular for rock climbing.
How are stacks and stumps formed?
Stacks and stumps form when waves erode a weakness in a headland using abrasion or attrition. The crack widens until a cave is formed. Waves continue to erode the back of the cave until eventually it pushes all the way through the headland forming an arch.
What is a stump and how is it formed?
A stump is formed through a series of erosional processes. This are corrasion (the effects of material suspended in the water being thrown against the headland), and hydraulic action (the effect of the build-up of pressure, as waves compress air in to cracks).
Are sea stacks rare?
Sea stacks are common along many of the world’s coastlines, and some have even become quite famous. Like other features found along shorelines, sea stacks are also in a constant state of flux, with new stacks emerging all the time while old ones disappear.
What is a stump geography?
Stumps. A stump is the eroded remains of a sea stack, often looking like a lump of rock sticking up from its surroundings. It is the last stage in the process that starts with a weakness in a cliff that develops into a cave, then an arch, a stack, and finally, a stump.
How is a stump made?
When the arch collapses, it leaves the headland on one side and a stack (a tall column of rock) on the other. The stack will be attacked at the base in the same way that a wave-cut notch is formed. This weakens the structure and it will eventually collapse to form a stump.
How are stumps created?
What is a sea stack in geography?
Isolated outcrops of rock standing in the ocean are called sea stacks, and they are remnants of rocky headlands that were eroded by wave action. You can see them along the Oregon coast at Myers Creek, Bandon, and Gold Beach.
