A geological feature formed when waves erode through a headland leaving a freestanding rock column is called a __________.

Explanation:
Waves eroding a headland carve out cracks and widen openings until a hole breaks through, forming a sea arch. If that arch collapses, what remains is a freestanding column of rock rising from the water—the sea stack. A beach is just deposited sediment along the shore, and a cove is a recessed inlet carved into the coast; an arch is the opening through the headland itself. The description given points to a sea stack.
