Which of the following describes a 'Tombolo' in coastal geomorphology?
A. A steep cliff formed by wave erosion along a headland
B. A depositional landform where an island is attached to the mainland by a narrow spit or bar of sand✓ Correct Answer
C. An accumulation of sand formed across the mouth of a bay, sealing it off from the open sea
D. A submerged wave-cut platform extending seaward from the base of a coastal cliff
💡 Solution & Explanation
A tombolo is formed when wave refraction and diffraction deposit sediment in the sheltered zone behind an island, building a spit or bar known as a tombolo that connects it to the mainland. Alternate choices describe wave-cut platforms, headland cliffs, or bar-sealed bays rather than island-to-mainland connections.
