When rock above a cave collapses, it forms a sinkhole. Sinkholes are depressions in the ground that are often caused by the erosion of underground caves or channels.
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.

The arch is made up of either sedimentary rock or metamorphic rock. Most likely sedimentary because the layers in the arch are distinct, solid bands of color, whereas a metamorphic rocks have swirly bands of color from the emense pressure the rock went through. Another reason the rock might be sedimentary is because the arch opening would not be as large if the rock was metamorphic rock, which can whithstand more erosion than sedimentary rock.
