A coastal landform formed by deposition that connects the coast to an island is called a what?

• A. Traction
• B. Surface stores
• C. Throughflow
• D. Tombolo

Answer: (D)

A tombolo is a coastal landform formed by deposition that connects the coast to an island. It develops when sediment carried by longshore drift is deposited in the sheltered area beyond the coastline, building a spit that grows across the water to join with an island. This bridging feature results from deposition, not hydrological processes, which is why terms like traction (the rolling movement of sediments), surface stores, and throughflow (water movement within soil) don’t describe a landform linking land to an island.
