A ledge is a narrow, flat surface that extends from a vertical surface, such as a wall or cliff. It can be found in various natural settings, like mountains or canyons, and is often formed through erosion or geological processes. Ledges can provide habitats for plants and animals, as well as vantage points for observing the surrounding landscape. In architecture, a ledge may refer to a shelf or projection on a building, often used for decorative purposes or to support other structures. Ledges can also be found in indoor settings, such as window sills or shelves, where they serve practical functions for holding items or enhancing aesthetics.
