When two sea caves on opposite sides of a headland unite, they form an arch. Over time, continued erosion can cause the arch to collapse, leaving behind a stack. Subsequent erosion can erode the stack to form a sea stack.
Sea cliffs: Steep rock faces along the coastline that are eroded by the constant force of waves. Sea caves: Hollowed-out spaces in coastal cliffs where waves have worn away softer rock layers. Wave-cut platforms: Flat, rocky areas at seashore level that are created by the gradual erosion of cliffs. Arch: A natural rock formation where a sea cave has eroded completely through a headland, leaving a bridge-like structure. Stack: A tall, isolated pillar of rock that is left standing as the surrounding cliff is eroded by waves.
Sea cliffs: High vertical cliffs formed by the erosion caused by waves hitting the coastline. Sea caves: Caves formed by wave action eroding the rock along the coastline. Headlands: High points of land that jut out into the sea, formed by differential erosion from wave action. Sea stacks: Isolated columns or pillars of rock that are left standing in the sea after the collapse of a headland. Wave-cut platforms: Flat areas at the base of sea cliffs formed by wave erosion and deposition of eroded material.
A person who studies caves is called a speleologist or a caver. They study the physical structure, formation, and geological features of caves, as well as the life forms that inhabit them.
Sedimentary rock forms from the layering of eroded rock material, which accumulates and undergoes compaction and cementation over time. Examples of sedimentary rocks include sandstone, shale, and limestone.
A mold forms when the original parts of an organism in a sedimentary rock are weathered and eroded. This mold is a hollowed-out impression of the organism's shape that is left behind after the actual remains have been removed.

The acid in the water forms it
The formation of stacks begins when the sea attacks small cracks in a headland, which causes them to open. The cracks gradually become larger and turn into small caves. Eventually an arch forms and collapses, leaving a pillar of rock (or stack) standing away from the coast.

Caves usually and mostly forms in sedimentary rocks. Example, Limestone.
The sea first forms sea caves then sea arches then sea stacks and finally it forms sea stumps which will eventually disappear.
