A rough surface is one that has an uneven texture, making it feel bumpy or coarse to the touch. This type of surface can be found in various materials, such as wood, stone, or metal. Rough surfaces can affect how objects interact with them, influencing grip, friction, and wear. In nature, many surfaces are rough, like the bark of a tree or the rocky ground. These textures can provide benefits, such as better traction for walking or climbing. In construction, rough surfaces are often used intentionally to enhance safety and stability in structures and pathways.
