A piece of land that juts into water and is usually smaller or narrower than a peninsula is called a spit.

Here are some key characteristics of a spit:

* Formed by longshore drift: Spits are created when prevailing winds and waves cause sediment to be transported along the coastline, eventually accumulating at a point where the coastline changes direction.

* Narrow and elongated: They are typically long and narrow, extending out into the water.

* Often curved: The end of a spit often curves back towards the mainland, forming a hook-shaped feature.

* May have a lagoon behind it: The spit can sometimes enclose a lagoon or a bay.

Examples of famous spits include:

* Dungeness Spit in Washington State, USA

* Spurn Point in England

* Chesil Beach in England
