Best Answer

A tombolo is a sandbar that connects the mainland to an island, forming a permanent or temporary isthmus, and the island can be known as a "tied island". Tombolos form from sand or sediment pushed along a shoreline.

It's because it just does. When longshore currents encounter a bay or bend in the coast with a shallow sheletered water , the materials carried will be deposited in the direction of the longshore drift, which is repeated zigzag movement of sediments in one direction along the coast. Over time, the accumulation of materials will result in a long, narrow ridge of sand with one end attached to the mainland and the other extending seawards to form a spit. When a spit joins nearby offshore island, it forms a tombolo.
