A sea stack forms under which condition?
Answer and explanation
Correct answer: When a sea arch roof collapses leaving an isolated rock pillar
A sea stack is an isolated pillar of resistant rock standing near a coast. Waves first enlarge weaknesses in a headland to form a sea cave, then the cave may develop into an arch. When the arch roof collapses, the detached pillar remains as a stack. A delta and barchan are depositional features, while cave calcite is a karst deposit, so option D is correct.
