Answer: Tombolo
Explanation:A tombolo is formed when wave action and longshore drift cause sand and sediment to accumulate and form a sand spit that connects an island to the mainland or another island. Tombolos are typically narrow and can be curved or straight, depending on the direction of the longshore drift and the shape of the coastline. Examples of tombolos can be found in various locations around the world, including the Tombolo della Giannella in Italy and the Murray Spit in the United States.
