Which coastal landform, characterized by a narrow strip of sand or shingle connecting an island to the mainland, is prominently observed along certain sections of the Kerala coastline?

💡 Solution & Explanation

A tombolo is a coastal depositional landform where an island becomes permanently connected to the mainland by a narrow spit of sand or gravel formed through wave refraction and longshore drift. Coastal landforms such as spits remain detached at one end, while barrier islands run parallel to the shore without connecting to the mainland.
