Headland.
sea stack
By erosion. Sea caves erode to become sea arches which erode to form sea stacks.
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.
the sea erodes the rock facing out to sea with corrasion etc this form a cave in the rock this gets bigger until it goes all the way through the rock to the other side - this causes an arch after a while the rock above the arch loses support and the rock left over standing in the sea is a stack when this falls over and gets eroded more, it forms a stump
sea stack
Headland,Sea Cave, Sea Arch, Sea stack,and wave-cut cliff. EXAMPLE WITH SEA ARCH AND SEA STACK: A sea arch is formed when two caves on opposite sides of a headland join. The sea arch collapses when the waves & weathered sediment (rock particles),hit it continuously in which a sea stack is formed. the sea arch is then .eroded and deposited in a new place.
A sea arch is an opening that was made naturally by the ocean by the sea water eroding the rock. Sea arches can also be formed by wind, or by the land. Or they can also be combination of all three. A sea arch is an arch that is made from an eroded cliff face. The water makes the sea arch after many years.
A sea stack by far. This is because if you imagine a cliff face constantly being eroded away by the waves, the first sign of erosion to appear will be a crack in the rock which will soon open up more and become a cave. Eventually, the waves will keep eroding away the wall until it comes out the other side and becomes an arch. The roof will then collapse due to more erosion and leave a high stack of rock stranded in the ocean. This is the sea stack.

You have to click the two arch buttons on the bottom left touch screen to dig.
earthquake
An arch in a cliff is formed through the erosion of softer rock layers by natural forces like wind, water, and ice. As these forces wear away the softer rock, a bridge-like structure of harder rock remains, creating the arch shape. Over time, the arch may collapse due to further erosion or structural weaknesses.
