A spit or sandspit is a deposition bar or beach landform off coasts or lake shores. For example, The Ram Setu or Adam bridge was Tombolo until 1500 CE. Spits are formed where the prevailing wind blows at an angle to the coastline, resulting in longshore drift. The beach sediments that are moving by lateral transport on the lee side of the island will accumulate there, conforming to the shape of the wave pattern. This is an accumulation of sand, shingles, and pebbles at the coast. Eventually, when enough sediment has built up, the beach shoreline, known as a spit, will connect with an island and form a tombolo.[3].
