Yields twice daily, exposed at low tide and submerged at high tide. Thus, they most commonly occur across artificial bay and river entrances due to the loss of kinetic energy in the current after wave refraction.

A landform that is a long, narrow, sinuous ridge composed largely of sand and gravel deposited when meltwater deposited sediment in a glacial tunnel Again we return to water as an agent of transport. Even though the percentage is low, the volume is large, so melting the glaciers away will raise sea level and flood the coastlines of the world. If the supply is not interrupted, and the spit is not breached by the sea (or, if across an estuary, the river), the spit may become a bar, with both ends joined to land, and form a lagoon behind the bar.
