Difference between Surfaces and Aerofoil

SURFACES vs AEROFOIL: NOUN

Plural form of surface.
A device that provides reactive force when in motion relative to the surrounding air; can lift or control a plane in flight
Information that has become public
The outermost level of the land or sea
The extended two-dimensional outer boundary of a three-dimensional object
A superficial aspect as opposed to the real nature of something
The outer boundary of an artifact or a material layer constituting or resembling such a boundary

A wing of an aircraft.
A structure shaped to produce lift when moving in air.
A plane or arched surface for sustaining bodies by its movement through the air; a spread wing, as of a bird.
A device that provides reactive force when in motion relative to the surrounding air; can lift or control a plane in flight
