Key facts?
A spit is a small, narrow, elongated landform that projects out into a body of water, usually from a beach or coastline. Spits are formed by the deposition of sediment, typically sand and gravel, carried by longshore drift or tidal currents, often developing at the mouth of a river or estuary where the change in current direction causes the deposition of material. Spits are typically curved or hook-shaped, with one end attached to the land and the other end free, ranging in size from a few meters to several kilometers in length, and are usually low-lying and narrow, with a relatively flat or gently sloping surface.
