Surfaces

Surfaces are the outermost layers or boundaries of objects, defining their shape and containment. They can be flat, curved, smooth, or textured, and play a key role in how objects interact with their environment—such as reflecting light, resisting wear, or enabling movement. In science and engineering, understanding surfaces helps in designing materials, studying textures, and analyzing how objects connect or separate. Essentially, a surface is the interface between an object and the outside world or another material, influencing both appearance and functionality.
