See all on Wikipediahttps://en.wikipedia.org/wiki/FinA fin is a thin component or appendage attached to a larger body or structure. Fins typically function as foils that produce lift or thrust, or provide the ability to steer or stabilize motion while traveling in water, air, or other fluids. Fins are also used to increase surface areas for heat transfer purposes,

A fin is a geological formation that is a narrow, residual wall of hard sedimentary rock that remains standing after surrounding rock has been eroded away along parallel joints or fractures. Fins are formed when a narrow butte or plateau develops many vertical, parallel cracks. There are two main modes of following erosion.The first is when water flows along joints and fractures …

See also: Fin. Some finned elements. In the study of heat transfer, fins are surfaces that extend from an object to increase the rate of heat transfer to or from the environment by increasing convection. The amount of conduction, convection, or radiation of an object determines the amount of heat it transfers.

The word was first used for the limbs of fish, but it is now also used to mean other animal limbs and human-made devices. The fins of fish are called: Dorsal fin on the back. These fins keep the fish from rolling over.
