INDIAN GEOGRAPHY

Detailed explanation-1: -A tombolo is a sandy isthmus. A tombolo, from the Italian tombolo, meaning ‘pillow’ or ‘cushion’, and sometimes translated as ayre, is a deposition landform in which an island is attached to the mainland by a narrow piece of land such as a spit or bar. Once attached, the island is then known as a tied island.

Detailed explanation-2: -A tombolo is formed when a spit connects the mainland coast to an island. A spit is a feature that is formed through deposition of material at coastlines. The process of longshore drift occurs and this moves material along the coastline.

The rocky island is connected to the mainland by a large sandbar, which forms part of Chesterman Beach, a popular destination among locals. An island attached to the mainland by a tombolo is known as a tied island.
